I received my new SIM card. Tried leaving it on for 24 hours, even cleaned the SIM card to make sure no dust, but all I am getting is sim not recognised. When putting my Nokia phones serial number in when requesting the new SIM card, it wouldn’t even recognise the number, so had to say I didn’t know it so I could just get the SIM card.I have received a text message this morning say it will cease working in 30 days if I don’t change over, but if the phone won’t recognise it, what are you supposed to do? It’s an absolute joke. I rely on this phone for my banking and drs and chemist, what do I do now?
