Test your actual locations
Use the provider’s postcode checker, then test home, work and travel. Ask whether Wi-Fi calling is supported on your plan and handset. Check local outages before changing tariff.
A troubleshooting sequence
Restart; toggle airplane mode; check the active SIM and data allowance; check the provider outage page; test another location. Take notes before contacting official support.
What to take to the provider
Have the tariff name, start date, current bill or usage screenshot and the exact question ready. You can ask our independent team to help frame those questions, but only the network can see your account or process changes.
Open a network dossier ↗For switching rules, see the Ofcom guide. For plan terms and charges, use your network’s current official documents.
