Check mobile coverage at the places where you work before choosing a device: a national 5G claim cannot tell you how a connection will perform indoors. Phone or cellular-tablet tethering can serve as an occasional backup, a USB modem suits a laptop-centred setup, a dedicated hotspot shares a portable connection, and a mains-powered SIM router suits a recurring work site. The network, data plan, device compatibility and your employer’s security requirements still need to work together.
If you move between homes, client sites and temporary workspaces, check the network at each regular stop rather than relying on a nationwide coverage claim. Ofcom’s local coverage guidance distinguishes indoor from outdoor predictions, which may differ from your experience inside a building.
A backup used for calls, screen sharing and uploads needs workable upload as well as download performance. Check the connection during normal working hours and consider the plan’s data allowance, particularly if other devices will use it too.
Before using a personal phone, SIM or networking device for employer or client data, confirm the approved setup with your organisation. The Information Commissioner’s Office advises organisations to assess remote-working systems for security risks.
Start with the network at your work locations, then choose the connection method and plan that fit your devices and working routine. Ofcom’s checker provides location-specific guidance, but buildings and other surroundings can change the result you experience.
Consider it: For occasional backup when you already have a suitable device and your carrier permits hotspot use.
Check: Carrier limits, data allowance and employer approval; a Wi-Fi-only tablet cannot share a cellular connection.
Consider it: For a compact, laptop-centred connection when broad sharing is not the main need.
Check: The work computer’s port and operating-system compatibility, as well as how the exact modem shares its connection.
Consider it: When several devices need one portable mobile connection without using your everyday phone.
Check: Charging, the supported SIM and network, and the device’s stated connection limit.
Consider it: For a recurring work site that needs shared Wi-Fi, or wired and fixed-broadband backup features where the model offers them.
Check: Power, ports, SIM requirements and whether the intended network works at that site.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage where you work | Compare host networks at each regular postcode using Ofcom’s indoor and outdoor 4G and 5G guidance. Test at the intended location if reliable calls are essential. | When I move between client sites or temporary workspaces, I need service inside the places where I work; about 36% of consumers put location reliability first. |
| Calls and data use | Test upload, download and stability during your usual work hours; check the plan’s allowance and hotspot terms. | If meetings, screen sharing and uploads must continue during a broadband outage, browsing alone is not enough. Meeting and data capacity is the primary need for about 29% of consumers. |
| Devices and work site | Count simultaneous devices and check the exact model’s sharing limit, power needs and any required Ethernet or WAN/LAN port. | At a recurring workspace, I may need to connect several devices or wired equipment rather than one laptop; about 21% of consumers put shared-site capability first. |
| Workplace approval | Confirm which personal devices and SIMs are permitted, then test the required VPN and authentication setup. | For work involving managed access or client data, a quick connection is useful only if the organisation permits it. About 14% of consumers primarily need an approved, straightforward backup. |
Ofcom’s location-specific guidance distinguishes indoor and outdoor predictions; walls and surroundings can affect the connection you actually get. A 5G-capable device cannot create a usable service where the selected network does not provide one.
Check each regular work location and the network behind the proposed SIM plan. Where locations vary, check the device’s 4G support as well as its 5G support.
Advertised device rates are not measurements of your work connection. Zoom’s published group-video requirements include upload bandwidth, so a download figure alone cannot establish call suitability.
Try your actual meeting application and VPN at a likely work time, paying attention to upload, connection stability and other devices using the link.
Apple says Personal Hotspot availability and connected-device limits can vary by carrier and device model. A mobile plan’s allowance and hotspot conditions also matter when backup use becomes regular.
Read the exact plan terms and confirm that the phone or cellular tablet can share data in the way your work setup requires.
GOV.UK states that surcharge-free roaming in EU and EEA countries is no longer guaranteed for UK mobile users. A plan that works for backup at home may have different roaming allowances and tethering conditions.
Before travelling, check the plan’s covered destinations, data allowance, tethering treatment and fair-use terms.
The Nighthawk M6 MR6150 is an example of NETGEAR’s portable 5G hotspot route for sharing a connection away from a fixed work site.
The Archer NX200 illustrates a SIM-router setup for a recurring workspace or fixed-broadband fallback.
D-Link’s DWM-222W is an example of a 4G USB-adapter route for a laptop-centred connection.
An existing iPhone or Wi-Fi + Cellular iPad can be considered for occasional Personal Hotspot use.
These portable hotspot and USB-adapter options relate to changing work locations and laptop-centred backup. Check the intended mobile network, computer or SIM requirements, plan terms and workplace approval for the exact setup before choosing one.

Consider this mobile hotspot if you need to share a portable backup connection rather than tether from your everyday phone.
The product name specifies 5G NR and AX3000 Wi-Fi 6. Confirm the exact model’s network-band and SIM compatibility, then check service at your work locations.

Consider this USB-adapter route for a laptop-centred backup, provided it fits your work computer.
The product name specifies 4G LTE, AX300 Wi-Fi 6 and USB. Check the DWM-222W/R variant’s operating-system, USB-port, SIM and network compatibility rather than relying on specifications for another variant.

Consider this mobile hotspot when you want portable Wi-Fi sharing and a suitable 4G connection is available where you work.
The product name specifies 4G LTE and AX300 Wi-Fi 6; it does not specify 5G. Confirm network-band and SIM compatibility and test the connection for your work calls.
Check the network first at the postcodes where you work. Ofcom’s mobile checker gives network-specific coverage guidance, but indoor conditions can differ from its predictions. Once you have a plausible network, check the device’s exact bands and SIM or eSIM format.
The required connection depends on the meeting settings and what else is using it. Zoom lists 720p group-video requirements of 2.6 Mbps down and 1.8 Mbps up, and 1080p requirements of 3.0 Mbps down and 3.8 Mbps up. Test your actual meeting application and VPN at the intended location; a rated device speed is not a substitute for that check.
An iPhone or Wi-Fi + Cellular iPad can share its cellular connection, according to Apple, if the carrier makes Personal Hotspot available. A Wi-Fi-only iPad cannot do this. Check your plan’s terms and your employer’s device policy, then test the work laptop and VPN with the intended tethering method.
Do not assume it will: GOV.UK says surcharge-free roaming in EU and EEA countries is no longer guaranteed for UK users. Before travelling, check your operator’s terms for the destination, data allowance and hotspot use.
Confirm which personal devices, SIMs and hotspots are approved, and whether the required VPN and authentication work over your proposed connection. The Information Commissioner’s Office advises organisations to assess remote-working systems for security risks; a technically working personal hotspot is not, by itself, workplace approval.
