Connectivity for modern life

The Data-Fi guide

A better starting point for broadband SIMs.

The right mobile broadband plan starts with your location, device and everyday use.

Check the location and the device

Mobile broadband uses a mobile network to provide a data connection. In a compatible router, it can share that connection with other devices. Start with coverage at the exact building or installation, rather than assuming the strongest phone signal elsewhere will give the same result. Walls, terrain, antenna position, the router and network conditions can all affect performance.

Check the router or tablet model, whether it is network-locked and which SIM format it accepts. An eSIM needs a compatible device and service; it is not a direct replacement for a physical SIM in every router. A phone tariff may also have different permitted-use conditions from a broadband tariff.

Estimate the data your household or team uses

List the devices and activities that will share the connection. Video calls, streaming, cloud backups, software updates and cameras can all influence the total. Existing usage records are more useful than guessing from the number of people alone. Allow for peaks as well as an average week.

Read the actual allowance and fair-use information. An unlimited label is not a guarantee of unlimited use without conditions, or of a particular download speed. Check out-of-bundle charges and any network-specific restrictions before agreeing.

Match the commitment to the job

Compare the minimum term, monthly charges, billing arrangements and cancellation information alongside the data. If the router will travel abroad, check the exact roaming destinations and allowance; UK availability does not establish overseas use. The Three plans currently offered here are UK-only, while the other networks have their own plan-specific roaming arrangements.

Explore our mobile broadband SIM options and the Vodafone, EE, O₂ and Three pages. For connected machinery rather than general internet access, consider an appropriate IoT service. Tell Data-Fi about your location and device if you would like help narrowing the options.
