Coverage
Check your signal before you switch.
Syncera Mobile runs on major UK networks through our network partner, Unboxed Mobile. Put in your postcode and we'll show you what to expect where you live and work.
Indicative only, based on partner network data. Outdoor coverage is usually better than indoor.
Wi-fi calling & VoLTE
Supported on most modern handsets, so you can still make calls where the signal is thin but the wi-fi isn't.
Try it without the risk
Because there's no contract, testing us is a month, not two years. Take an eSIM, keep your old SIM in the other slot, and see how it goes before you move your number.
Somewhere we're weak?
