Buying guide
Mobile hotspot devices: choose for backup or regular use
Choose a mobile hotspot for UK use by network compatibility, data plan, indoor signal, connected-device load, ports and power arrangements.
Start with the shape of the decision
A dedicated hotspot separates mobile connectivity from a phone, which can help with broadband backup or repeat group use. The useful choice begins with coverage and allowance at the intended location, not the largest advertised mobile-network number.
Free checks first
- Test the intended mobile network at the exact indoor location and at busy times.
- Use phone tethering temporarily to estimate data use and device load.
- Check whether an existing router accepts USB tethering or a mobile-network failover connection.
Use your own evidence
