My IPhone 5 has stopped working as of today.
It shows I am still connected to the Network with a good signal, however all calls I try to make fail, texts are showing not delivered and I cannot receive calls or texts?
How do I start problem solving this?
If the problem is not a service/SIM issue @brianmcintyre , does mobile data work (i.e. not WiFi).
I ask since a phone which has been blacklisted will not operate for calls and texts, but will for mobile data. Unscrupulous sellers have been known to, once they have sold on a used phone, declared it lost/stolen in order to claim on insuarance, resulting in the phone becoming blacklisted.
Hopefully this does not apply to you.
