Check fixed-broadband availability and each mobile network’s predicted indoor coverage for the flat before choosing equipment. Fixed broadband makes sense if activation fits your move-in timetable and any installation arrangements are settled; a 4G/5G home router is an alternative for several devices when indoor signal and plan terms suit your use. For a short or lighter-use gap, consider a phone or portable hotspot, or a SIM in compatible equipment—but coverage predictions cannot guarantee service inside the flat.
If several devices need internet before fixed broadband starts, compare the provider’s activation date with predicted indoor mobile coverage at the flat. A temporary plan should last long enough for the expected gap without committing you to a term you do not need.
If building access or installation timing is uncertain, a plug-in mobile-broadband router avoids waiting for fixed-line work. It is worth considering only if the chosen network is usable indoors and the plan suits the household’s data use.
For a brief gap or access while moving around, a phone hotspot or portable hotspot may be enough. If you already own compatible cellular equipment, check whether a suitable SIM plan meets the need before buying another device.
Start with what can work at the exact flat, then match the activation time, equipment and plan to how long and how heavily you will use the connection.
| Priority | What to check | Your needs |
|---|---|---|
| Fixed availability | Use Ofcom’s broadband checker, then ask a provider about service at the exact flat and its activation date. A predicted result is not a service guarantee. | I need to know whether a fixed connection can be ready soon enough, or whether I need a temporary connection first. |
| Indoor mobile signal | Compare predicted in-home coverage by underlying network, not just outdoor 4G or 5G coverage. Ofcom notes that local conditions can make service at a property differ from its prediction; check the provider’s current network status too. | The connection has to work inside my flat, where I will actually use it. |
| Data and sharing | Compare plan allowances and usage rules with your streaming, calls and downloads. Check how the chosen device shares a connection and which devices need to use it. | Several people or devices may be online at once, so a phone plan that covers occasional use may not suit our household routine. |
| Setup and term | Ask whether fixed service needs only activation or new work and building access. For a mobile bridge, check the plan term against the expected wait for fixed broadband. | I want to get connected without taking a long mobile commitment for a short move-in gap. |
| Equipment compatibility | For a SIM or eSIM, check the device’s supported format, network compatibility, lock status and plan rules. A SIM creates shared Wi-Fi only when compatible equipment can share its connection. | If I already have a cellular device or router, I would rather check whether it can do the job before buying more equipment. |
Outdoor coverage does not establish that the signal will be usable inside the flat. Ofcom says buildings and local conditions can affect the result.
Compare predicted in-home coverage for each underlying network at the postcode, and check the chosen provider’s current network status.
A phone hotspot uses the handset’s data and battery. As O2 explains, a dedicated portable hotspot has its own SIM and battery, which avoids relying on the phone as the host.
Use the phone option for a short or light-use gap; consider dedicated equipment if several devices need a shared connection for longer.
If fixed broadband becomes active sooner than expected, the mobile and fixed service periods may overlap.
Get an address-specific activation estimate first, then compare mobile plan terms with the likely gap and any intention to keep mobile broadband as the main connection.
An overlapping contract can leave you managing two services until the mobile plan can be changed or ended under its terms.
Ofcom’s availability information is predictive, and an order may still involve installation or access to parts of the building.
Ask the provider whether it can activate existing equipment or needs new work. If work affects areas you cannot authorise, confirm the arrangements with the landlord, freeholder or managing agent before the appointment.
These providers illustrate different mobile-broadband approaches; the relevant network, device and plan still need checking for your flat.
EE offers home mobile-broadband hubs and portable Wi-Fi devices, including options it presents for renters and movers.
Three offers 4G/5G home-broadband plans using a plug-in hub rather than a fixed line.
Vodafone offers address-checked 5G home broadband as well as portable hotspots, dongles and data SIM options.
O2 provides guidance and support for portable mobile broadband and pocket hotspots.
These options cover a portable hotspot, a home mobile router and SIM plans that may suit compatible equipment. Check indoor network coverage, device compatibility and plan terms before using any of them as a connection for the flat.

A portable hotspot to consider for a short gap or access away from the flat. Check its compatibility with your chosen UK network, the applicable data plan and predicted indoor coverage before relying on it at home.
No image available
A mobile-router option for a flat that needs a shared connection while fixed broadband is delayed. Check the selected network’s indoor coverage, router compatibility and a data plan suited to household use.
No image available
A SIM-plan option if you have suitable cellular equipment. Compare the stated 100 GB UK data allowance with expected use, and confirm the SIM format, device compatibility, sharing rules and network coverage.
No image available
A SIM-plan option for compatible equipment when 40 GB of UK data fits your expected use. Check the device and SIM format, whether the plan permits your intended sharing setup, and indoor coverage at the flat.
No image available
The plan advertises unlimited UK data for use in compatible equipment. Read the conditions attached to that claim and confirm device compatibility, connection-sharing rules and indoor network coverage before choosing it for household use.
No. Ofcom’s checker distinguishes predicted indoor and outdoor coverage, but walls, buildings and local conditions can change what you experience. Compare the underlying networks at the postcode and, where practical, test the chosen connection at the flat.
Choose fixed broadband if a provider can activate it at the exact flat in time and any installation arrangements are settled. A 4G/5G home router is an alternative during a delay if the chosen network has suitable indoor coverage and its plan fits the household’s expected use and timeframe.
It may be enough for a short, light-use gap or one main device, provided the phone has usable signal and suitable data. It also uses the phone’s battery; O2 notes that a dedicated portable hotspot instead has its own SIM and battery.
Ask the provider whether it can activate existing equipment or needs new work, drilling or access to shared areas. If the work involves property you cannot authorise, confirm the required arrangements with the landlord, freeholder or managing agent before the appointment.
Only if the equipment is compatible with the SIM or eSIM, the chosen network and connection sharing. Check the device’s SIM format and lock status, the plan’s usage rules and predicted indoor coverage; a SIM alone does not create home Wi-Fi.
