Business Mobile Phone Services
Keep your people connected wherever work takes them
Your employees no longer work from one desk.
They work from home, visit customers, travel between offices, attend sites and respond while they are on the move.
For many of them, a mobile phone is now one of their most important business tools.
It provides access to calls, email, Microsoft Teams, company files, cloud applications, authentication codes and customer information.
That means business mobile services should be about more than choosing a handset and signing a contract.
Your mobiles need to be reliable, affordable, secure and properly managed throughout their working life.
Stratiis can help you bring business mobile contracts, devices, number management, security and support together as part of your wider technology environment.
The right devices. The right tariffs. Better control and support.
Are your business mobiles becoming difficult to manage?
Mobile services often grow without a clear plan.
A phone is ordered when someone joins. Another SIM is added for a new role. An employee leaves, but nobody checks whether the number or contract is still active.
Over time, the business can end up paying for services that no longer match how people work.
You may recognise some of these problems:
- Employees use personal mobiles for business calls
- Mobile contracts renew at different times
- Nobody has a complete list of devices and numbers
- Former employees still have access to business data
- Unused SIMs continue to be billed
- Staff regularly exceed their data allowances
- Roaming costs come as a surprise
- Lost or stolen phones are not dealt with quickly
- Mobile devices are not protected by company security policies
- New starters wait too long for a phone
- Employees choose unsuitable devices
- Devices cannot be remotely locked or wiped
- Several suppliers are involved when support is needed
- Mobile costs are difficult to understand
These issues create unnecessary cost and risk.
A managed business mobile service can give you better visibility and a clearer process for every device and user.
What are business mobile services?
Business mobile services provide the contracts, SIMs, devices and support employees need to make calls, use data and securely access company systems while away from the office.
A business mobile service may include:
- Mobile voice and data plans
- SIM-only contracts
- Smartphones and tablets
- Number porting
- Shared data allowances
- 4G and 5G services
- International roaming
- Usage monitoring
- Device setup
- Mobile security
- Mobile Device Management
- Joiner and leaver support
- Lost-device response
- Contract and billing reviews
- Device replacement
- Ongoing technical support
The right service depends on the employee’s role.
A senior manager, field engineer, customer-service employee and occasional mobile user may each need a different device and data allowance.
We help you match the service to the person rather than putting everyone on the same package.
Our business mobile services
Business mobile contracts
A business mobile contract should reflect how your employees actually use their devices.
We can help you review:
- Call usage
- Data usage
- Number of users
- Device requirements
- Coverage
- Roaming
- Contract terms
- Shared allowances
- Upgrade cycles
- Support requirements
- Expected growth
This can help avoid paying for allowances employees do not use or choosing plans that regularly result in additional charges.
We also help you understand what is included, what costs extra and how long the organisation is committed.
SIM-only plans
Not every user needs a new handset.
A SIM-only plan may be suitable when:
- The existing device is still fit for purpose
- The business already owns the handset
- A user only needs voice and data
- You want greater device flexibility
- A tablet or router needs mobile data
- A temporary employee needs connectivity
- You want to separate device and airtime costs
SIM-only arrangements can reduce monthly costs, but the business still needs a plan for device ownership, security, support and replacement.
Business smartphones and devices
The cheapest phone is not always the lowest-cost option.
A device should be selected based on:
- Employee role
- Required applications
- Camera or scanning needs
- Battery life
- Storage
- Screen size
- Durability
- Security support
- Operating-system updates
- Expected lifespan
- Accessories
- Repair and replacement options
A field-based employee may need a rugged device and strong battery life.
A manager may need dependable access to Teams, email and documents.
An occasional user may only need a simple device for calls and authentication.
We help you avoid over-specifying devices while ensuring employees have the tools needed to work effectively.
Mobile number porting
Employees and departments may already have mobile numbers that customers and suppliers know.
These numbers can often be transferred to a new business mobile service through number porting.
A successful transfer depends on accurate account information and careful timing.
Stratiis can help you:
- Identify every active number
- Confirm ownership
- Gather transfer details
- Coordinate the port
- Arrange replacement SIMs
- Plan user communication
- Test incoming and outgoing calls
- Avoid unnecessary service cancellation
Existing services should not be cancelled before the transfer is complete.
Shared data plans
Some businesses benefit from sharing a data allowance across several users.
This can reduce the risk of one employee paying for unused data while another regularly exceeds their allowance.
Shared plans may be useful where:
- Usage varies between employees
- Teams travel at different times
- Some users consume little data
- Several devices need occasional connectivity
- Costs need to be managed centrally
The total allowance still needs to be monitored.
A shared plan does not remove the need to understand unusual or excessive usage.
4G and 5G mobile connectivity
Modern mobile services can support more than telephone calls.
Employees may use 4G or 5G for:
- Microsoft Teams
- Cloud applications
- File access
- Video meetings
- Mobile hotspots
- Remote working
- Temporary office connectivity
- Backup internet
- Tablets and specialist devices
Coverage and performance vary by location, network, building and device.
We consider where your people actually work rather than recommending a network based only on national coverage claims.
International roaming
Employees travelling abroad can create unexpected costs if roaming is not planned properly.
A business mobile policy should consider:
- Countries visited
- Frequency of travel
- Call requirements
- Data usage
- Travel add-ons
- Fair-use limits
- Restricted destinations
- Local Wi-Fi risks
- Personal usage
- Reporting and approval
Employees should know what is included before travelling.
They should also understand how to protect business information while using hotels, airports and public networks.
Mobile usage monitoring
Mobile reporting can help you understand:
- Data consumption
- Call usage
- Roaming
- Out-of-bundle charges
- Unused SIMs
- Unusual activity
- High-cost users
- Services that are no longer needed
The aim is not to monitor employees unnecessarily.
It is to control cost, identify risk and ensure the business is paying for services that are still required.
Consolidated billing
Managing several mobile accounts and invoices can take time.
A more organised service can provide clearer billing across:
- Users
- Numbers
- Devices
- Data usage
- Additional charges
- Roaming
- Contract terms
- Departments
- Cost centres
This can make it easier to allocate costs and identify unexpected changes.
Mobile Device Management
A business mobile is not just a telephone.
It may hold company email, Teams messages, customer data, files, passwords and authentication applications.
Mobile Device Management, often called MDM, gives the organisation more control over how approved devices access company information.
Depending on the platform and configuration, MDM may allow you to:
- Enrol devices
- Apply security settings
- Require screen locks
- Enforce encryption
- Manage business applications
- Block unsupported devices
- Separate business and personal information
- Monitor compliance
- Remove company data
- Lock or wipe lost devices
- Restrict risky features
- Manage operating-system requirements
For organisations using Microsoft 365, Microsoft Intune may form part of the mobile-management approach.
The right design depends on whether devices are owned by the business, owned by employees or shared.
Business-owned and personal devices
There are several common ways organisations provide mobile access.
Business-owned devices
The organisation purchases and manages the device.
This can provide stronger control over:
- Security
- Applications
- Updates
- Replacement
- Support
- Data removal
- Ownership
It may also create higher device and management costs.
Bring Your Own Device
Bring Your Own Device, or BYOD, allows employees to use personal devices for work.
This may reduce equipment costs and allow employees to use a device they already know.
However, it raises important questions:
- What business data can be accessed?
- Can company information be removed without deleting personal data?
- What happens when the employee leaves?
- Who supports the device?
- Which devices are acceptable?
- What privacy should the employee expect?
- How are lost devices handled?
- Is mobile access optional or required?
BYOD should be supported by a clear policy and appropriate technical controls.
Choose Your Own Device
Some organisations allow employees to select from a small approved list of business-owned devices.
This can balance employee choice with easier security, purchasing and support.
Corporate-owned, personally enabled devices
The business owns and manages the phone but allows reasonable personal use.
The policy should explain:
- Acceptable use
- Personal costs
- Application installation
- Privacy
- Monitoring
- International use
- Device return
- Damage and replacement
Stratiis can help you consider the practical technology requirements for each approach.
Mobile security
Mobile devices can create serious security risks because they travel outside the office and may contain access to several company systems.
Common risks include:
- Lost or stolen phones
- Weak screen locks
- Unsupported operating systems
- Malicious applications
- Phishing messages
- Public Wi-Fi
- SIM-swap fraud
- Unmanaged personal devices
- Stored company files
- Shared passwords
- Former employees retaining access
- Devices without encryption
A mobile-security approach may include:
- Multi-factor authentication
- Mobile Device Management
- Device encryption
- Strong screen locks
- Automatic locking
- Approved applications
- Conditional Access
- Remote locking and wiping
- Mobile threat protection
- Regular updates
- Restricted administrator access
- Joiner and leaver controls
- User awareness training
Mobile security should form part of your wider cybersecurity strategy rather than being left to the employee.
Lost or stolen business mobiles
A lost phone is not only a hardware problem.
It may provide access to:
- Microsoft Teams
- Customer records
- Cloud applications
- Company files
- Password-reset messages
- Authentication applications
- Contact information
Employees should know exactly what to do when a device is lost or stolen.
A response process may include:
- Report the device immediately
- Suspend or replace the SIM
- Lock the device
- Remove business data
- Reset exposed credentials
- Review account activity
- Inform the appropriate manager
- Assess whether personal data was exposed
- Provide a replacement device
- Document the incident
The sooner the business is told, the faster the risk can be reduced.
A clear process is more effective than relying on employees to work out what to do during a stressful situation.
Joiners, movers and leavers
Mobile services should be included in your employee lifecycle process.
When someone joins
The organisation may need to:
- Choose a device and plan
- Allocate a number
- Configure the handset
- Enrol it in device management
- Install approved applications
- Apply security policies
- Provide accessories
- Record the asset
- Explain acceptable use
When someone changes role
Their mobile requirements may change.
You may need to review:
- Data allowance
- International use
- Applications
- Access permissions
- Device type
- Department billing
- Shared numbers
When someone leaves
You should:
- Recover the device
- Suspend or transfer the number
- Remove company access
- Wipe business data
- Remove the user from device management
- Check accessories
- Reassign or securely dispose of the device
- Review outstanding contracts
- Redirect important calls where required
A mobile number may belong to the organisation even when it has been used by one employee for several years.
The business should retain control of customer-facing numbers.
Business mobiles and Microsoft 365
Business mobile devices are often used to access Microsoft 365 services, including:
- Outlook
- Microsoft Teams
- OneDrive
- SharePoint
- Microsoft Authenticator
- Microsoft 365 applications
- Company contacts
- Calendars
This can improve productivity, but access should be controlled.
Microsoft technologies such as Entra ID, Conditional Access and Intune can help determine:
- Who can sign in
- Which devices are permitted
- Whether the device meets security requirements
- Whether multi-factor authentication is required
- Which applications can access company data
- What happens when the user leaves
Because Stratiis supports Microsoft 365, devices, cybersecurity and mobile services, we can consider the entire user experience rather than treating the SIM contract separately.
Business mobiles and Unified Communications
Mobile services can form part of a wider Unified Communications strategy.
Employees may use one device for:
- Mobile network calls
- Hosted Voice applications
- Microsoft Teams Phone
- Video meetings
- Instant messaging
- Business contacts
- Voicemail
- Customer applications
This can help mobile employees remain connected to the same communication environment as office-based staff.
For example, an employee may answer the main business number through a Hosted Voice or Teams application while still using the mobile network for personal or direct business calls.
Business mobiles and Hosted Voice
A Hosted Voice mobile application can allow employees to make and receive calls using the business telephone system.
This can provide:
- Business number presentation
- Access to company contacts
- Call transfers
- Voicemail
- Call history
- Department call groups
- Reduced use of personal numbers
The application still depends on suitable Wi-Fi or mobile data.
The mobile contract, device and Hosted Voice platform should therefore be planned together.
Mobile services for field-based teams
Field employees may rely heavily on mobiles to complete their work.
They may use them for:
- Job scheduling
- Navigation
- Photographs
- Customer signatures
- Stock systems
- Time recording
- Lone-worker applications
- Video calls
- Site communication
- Access to documents
- Reporting issues
- Multi-factor authentication
These users may need:
- More durable devices
- Protective cases
- Better battery life
- Vehicle chargers
- Larger data allowances
- Reliable regional coverage
- Replacement processes
- Remote support
- Mobile Device Management
The device should fit the working environment.
A standard consumer handset may not be suitable for construction sites, warehouses or demanding outdoor work.
Mobile services for hybrid workers
Hybrid employees may use their mobile to:
- Join Teams calls
- Check email
- Approve authentication requests
- Access calendars
- Contact customers
- Receive business calls
- Use mobile hotspots
- Access company files
This makes the mobile device part of the employee’s daily IT setup.
It should be included in:
- User onboarding
- Security policies
- Technical support
- Asset management
- Business continuity
- Employee offboarding
Mobile connectivity as internet backup
4G or 5G can sometimes provide backup connectivity for an office, temporary location or individual employee.
It may be used for:
- Router failover
- Temporary office setup
- New-site connectivity
- Home-working backup
- Emergency access
- Events
- Construction sites
- Mobile teams
The suitability depends on:
- Local signal
- Network coverage
- Building construction
- Data allowance
- Number of users
- Applications
- Hardware
- Antenna placement
A mobile backup service should be tested before it is needed.
The benefits of managed business mobile services
Better cost control
Clearer reporting can help identify unused SIMs, excessive data usage, roaming costs and unsuitable plans.
Faster employee onboarding
Devices, numbers, applications and security settings can be prepared through a consistent process.
Stronger security
Mobile devices can be managed as part of the organisation’s wider identity, device and cybersecurity environment.
Easier support
Employees have one clear route for help with the device, SIM, Microsoft applications and business access.
Improved number ownership
The organisation can maintain control of important customer-facing mobile numbers when employees leave.
More suitable devices
Employees receive phones and plans that match their roles rather than a one-size-fits-all package.
Clearer contract management
Renewal dates, commitments and usage can be reviewed rather than allowing contracts to continue unnoticed.
Better business continuity
Mobile applications and data can help employees remain connected when an office or fixed internet service is unavailable.
What are the risks of unmanaged business mobiles?
Paying for unused services
SIMs and contracts may remain active after users leave or roles change.
Losing business numbers
A number may be registered personally or transferred without the organisation’s knowledge.
Unsecured access to company data
Devices may lack encryption, screen locks, updates or remote-wipe capabilities.
Weak leaver processes
Former employees may continue to access email, Teams or cloud applications.
Unexpected roaming charges
Employees may travel without understanding allowances and restrictions.
Unsupported devices
Older phones may stop receiving operating-system or security updates.
Personal and business data becoming mixed
Without proper controls, it may be difficult to remove company data from an employee-owned device.
Slow response to lost devices
Delays in reporting and locking a phone can increase the chance of data exposure.
No visibility of mobile spending
Bills may be paid without anyone reviewing whether the services are still required.

What should you look for in a business mobile provider?
Understanding of employee roles
A provider should ask how each group of employees uses mobile technology.
They should not automatically recommend the same device and allowance for everyone.
Clear tariffs and terms
You should understand:
- Monthly cost
- Included calls
- Data allowance
- Shared data rules
- Roaming
- Out-of-bundle charges
- Contract length
- Upgrade terms
- Device ownership
- Early termination costs
- Replacement arrangements
Device-management capability
The provider should understand how phones will be configured, secured, tracked and removed from service.
Microsoft and cybersecurity knowledge
Mobile devices often provide access to important business systems.
The provider should understand identity, Microsoft 365, device management and security rather than looking only at airtime.
A clear support process
Find out who will help when:
- A phone is lost
- A SIM stops working
- A user cannot access email
- A device needs replaced
- A number needs transferred
- An employee leaves
- Roaming does not work
- A mobile application fails
Regular contract reviews

Frequently asked questions
How much do business mobile contracts cost?
The cost depends on:
- Number of users
- Device choice
- Data allowance
- Call usage
- Contract term
- Shared data
- International roaming
- Device-management requirements
- Support
- Replacement arrangements
We review your existing usage before recommending a plan.
Are business mobile contracts better than personal contracts?
Business contracts may provide:
- Central billing
- Account management
- Shared data
- Business support
- Number ownership
- Usage reporting
- Device-management options
- Easier user changes
The exact benefits depend on the provider and service.
Should we choose SIM-only or handset contracts?
SIM-only may be suitable when your current devices are still usable or the business prefers to buy hardware separately.
A handset contract may spread the device cost across the agreement.
The best option depends on device lifecycle, cash flow, flexibility and total cost.
Can we keep our existing mobile numbers?
In many cases, yes.
Numbers can normally be transferred through mobile number porting.
The current account details need to be accurate, and the existing service should remain active until the transfer is complete.
Can employees use personal phones for work?
They can, but the organisation should have a Bring Your Own Device policy and suitable security controls.
The business must also consider privacy, support, data removal and what happens when the employee leaves.
What is Mobile Device Management?
Mobile Device Management allows an organisation to apply security and management controls to approved devices.
This may include enforcing screen locks, managing applications, checking compliance and removing business data.
Can a lost business phone be remotely wiped?
Yes, when the device has been enrolled in an appropriate management platform and configured correctly.
Depending on the setup, it may be possible to remove business data without deleting personal information.
Can Stratiis manage iPhones and Android devices?
Yes.
The exact management options depend on the device, ownership model, operating system and mobile-management platform.
Do all employees need the same mobile plan?
No.
Plans should reflect role, data use, travel, applications and working location.
A field employee may require more data than an office-based user.
Can you provide mobile data for tablets and routers?
Yes.
Data-only SIMs may be suitable for tablets, routers, temporary offices, backup connections and specialist equipment.
Can business mobiles integrate with Microsoft Teams?
Yes.
Employees can use the Microsoft Teams mobile application for meetings, messages and, where configured, business telephone calls.
Can a mobile replace a desk phone?
For some users, yes.
A mobile device combined with Hosted Voice or Microsoft Teams Phone may provide the calling features they need.
Reception and high-volume call handlers may still benefit from desk phones or specialist tools.
What happens to a mobile number when an employee leaves?
Where the organisation owns the contract, the number can normally be retained, reassigned or redirected.
This is important when customers regularly contact that number.
How can we reduce mobile costs?
Common opportunities include:
- Removing unused SIMs
- Reviewing data allowances
- Moving suitable users to SIM-only
- Reducing roaming charges
- Standardising devices
- Reviewing contracts before renewal
- Reassigning existing equipment
- Monitoring out-of-bundle usage
Can Stratiis support lost or stolen mobiles?
Yes.
We can help suspend the SIM, secure the business account, remove company data where possible and arrange a replacement.
Employees should report lost devices immediately.
Give your mobile employees the right tools and support
Business mobiles should help your people work from anywhere without creating unnecessary cost or security risks.
That requires more than a handset and a monthly tariff.
You need clear ownership, suitable devices, secure access, reliable support and a process for every stage from employee onboarding to device replacement and offboarding.
Stratiis can help bring mobile contracts, devices, Microsoft services, security and communications together as one managed environment.
Let’s review your current mobile estate, identify unnecessary costs and make sure every user has the right device, tariff and protection.
