Mobile broadband.

Work from your own contract.

A 4G/5G home hub uses mobile signal; a fibre or cable service uses a fixed connection. Compare them by address, not just headline speed.

Check signal indoors, any data policy, router placement, contract length and return rights.

Three useful checks

1. Identify the provider, plan name and date of your current agreement.
2. Check the full postcode, device compatibility, pricing and the current provider terms that apply to you.
3. Save a copy of the written answer before changing or cancelling the service.
