Workers changing locations
If you work from several addresses, compare indoor and outdoor coverage for each one and test reception where you actually sit. Ofcom’s coverage checker provides predictions, which can differ from your experience.
Who this guide is for
Workers sharing a mobile connection
If your laptop and other devices need to use one mobile connection, check the selected plan’s tethering terms, data allowance, device capacity and how the hotspot will be powered. Three describes tethering on its specified phone plans; check the terms for the plan you intend to use.
Single-device mobile workers
If you mainly work on one tablet or laptop, confirm that the exact device has cellular hardware and supports the SIM or eSIM setup offered by your provider. Apple’s setup guidance applies to Wi-Fi + Cellular iPads, not Wi-Fi-only models.
What to check before choosing
Compare the connection at your work locations first, then check that the device and plan suit your applications, sharing needs and voice requirements. Each row below focuses on a different first priority for consumers choosing mobile connectivity for work.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Reception at work locations | Check indoor and outdoor predictions for each postcode, identify the underlying network, and test at your working position. | I need a connection where I actually work, not just a favourable postcode-wide prediction. Around 31% of consumers put location reliability first. |
| Work-application performance | Test the applications you use, including uploads and video calls, on the shortlisted network during representative work sessions. | I need calls, meetings or uploads to work rather than simply seeing a signal indicator. Around 25% of consumers prioritise application performance. |
| Data allowance and plan terms | Check the exact plan’s allowance, tethering and device-use terms, plus any recurring charges or services not included. | I want a plan that fits regular work use and does not leave an essential service outside my allowance. Around 19% of consumers put plan suitability first. |
| Sharing capacity and power | Check how many devices need to connect together and the exact hotspot’s stated connection limit and battery runtime. | I need several work devices to stay connected through a session, and I need to plan for charging. Around 13% of consumers prioritise sharing capacity and power. |
| Device and voice compatibility | Confirm cellular hardware and SIM or eSIM support; check voice service separately if calls are essential. | I need mobile data or voice communication to work on the device I choose, rather than assuming one guarantees the other. Around 12% of consumers put device and voice compatibility first. |
Ofcom’s checker shows predicted coverage by network, while its performance guidance is not a guarantee at your desk. For a specific workload, use the requirements of the application you rely on: Zoom, for example, recommends 2.6 Mbps upload and 1.8 Mbps download for 720p group video in its Web App. Those figures apply to that Zoom mode, not every kind of remote work.
Buying pitfalls
-
Treating a coverage prediction or headline speed as proof of reliable work access
Ofcom cautions that predicted coverage can differ from real experience. A device’s rated speed also does not establish the performance available at your work location.
Use coverage maps to shortlist networks, then test your actual calls and work applications where and when you expect to use them. Keep rated specifications separate from measured connection performance.
-
Choosing a data-only arrangement when you also need calls and texts
Mobile data and ordinary voice service are not interchangeable. Three states that calls and texts may be charged outside the allowance when its business MiFi SIM is used in a device that makes calls and texts.
Check the selected plan’s voice, text and data inclusions, and confirm how you will make essential calls.
-
Comparing a business plan by its headline charge alone
Three’s business MiFi terms identify conditions such as VAT, recurring price changes and charges outside the allowance. These details apply to that provider’s plan terms, not to every mobile plan.
Read the full terms for the particular plan and compare the payment conditions and included services that matter to your use.
-
Assuming every version in a product family has the same features
Specifications can depend on the hardware revision or variant. For example, the cited TP-Link M7350 specifications apply to V9, while direct mobile data on an iPad requires a Wi-Fi + Cellular model.
Check the exact revision or cellular variant on the product listing and the device you receive before relying on a specification.
Relevant brands to consider
TP-Link
Portable mobile Wi-Fi hardware, including the M7350 V9 for sharing a 4G connection.
- TP-Link’s UK specifications for the M7350 V9 list support for up to 10 devices and up to 8 hours of working time.
- These are rated specifications for V9, not independent performance results or specifications for every M7350 revision.
NETGEAR
The UK Nighthawk M6 MR6150 is a 5G hotspot option with Wi-Fi 6.
- NETGEAR’s UK product page lists support for up to 32 concurrent devices.
- A stated device limit or advertised Wi-Fi speed does not establish mobile-network performance or how well several demanding applications will run at once.
Apple
Wi-Fi + Cellular iPads provide a direct mobile-data option, and supported iPhones can use Wi-Fi calling subject to provider and device support.
- Apple’s guidance explains mobile-data plan setup for Wi-Fi + Cellular iPads.
- Direct cellular access requires the cellular iPad variant. SIM and eSIM support depends on the model and provider; Wi-Fi calling also needs a working Wi-Fi connection.
Three
Three offers phone tethering and mobile broadband options, including data SIMs and business MiFi plans.
- Three describes hotspot use on its specified unlimited phone plans and data SIM use in tablets, laptops and MiFi routers.
- Plan inclusions and charges vary by service. Three’s business MiFi terms distinguish UK data from chargeable calls and texts, and set out payment conditions for that plan.
Vodafone
Vodafone documents Wi-Fi calling for compatible business devices and guidance for Wi-Fi calling through its 5G Hub.
- Vodafone states that calls and texts on its business Wi-Fi calling service are rated according to the relevant plan.
- Support depends on the device and service. Vodafone warns that Wi-Fi emergency calls using its 5G Hub may be interrupted if power or Wi-Fi fails.
Joybuy product options
These options cover several ways to get mobile data for work away from fixed broadband: a separate hotspot, a cellular tablet, a phone and a UK data SIM. The right route depends on the network available where you work and whether you need to share the connection or use data directly on one device.

Frequently asked questions
How do I check coverage for several work locations?
Check each postcode separately, compare indoor and outdoor predictions, and identify the network used by each provider. Ofcom explains that predicted coverage may differ from your experience, so test calls and work applications at your actual working position before relying on a connection.
How much connection speed do I need for video meetings?
Use the requirements for your actual application and meeting mode. Zoom recommends 2.6 Mbps upload and 1.8 Mbps download for 720p group video in its Web App; those figures are specific to that use and do not guarantee meeting quality or set a universal threshold for remote work.
Can Wi-Fi calling help if I do not have fixed broadband?
Only if another working internet-connected Wi-Fi network is available. Wi-Fi calling uses an existing internet connection; it does not provide an independent connection where neither mobile data nor another usable internet service is available.
How do I check whether a tablet or laptop can use mobile data?
Confirm that the exact model has cellular hardware, then check SIM or eSIM compatibility and provider activation. Apple’s mobile-data setup guidance is for Wi-Fi + Cellular iPads, while Microsoft’s eSIM guidance requires a PC with cellular connectivity.
Can a mobile broadband SIM replace a normal voice SIM?
Do not assume that it can. Three states that calls and texts may be charged outside the allowance when its business MiFi SIM is put in a device that makes calls and texts. Check the selected plan’s voice and text terms separately from its data allowance.
