Ring or WhatsApp and ask your question out loud โ€” coverage, switching, a deal you're not sure about, a bill that stalled, a call that smelt fishy. We'll talk it through in plain English.

Calls: standard landline rate (020), usually inside your inclusive minutes. WhatsApp: free on your data. We give general guidance only โ€” we can't open or touch any network account, and we NEVER ask for passwords, one-time codes, banking or card details.
