I recently stopped being able to make calls or send and receive texts. When I try to, I get a message saying "cellular network is not available. Connect to a wireless network to make a call"
Back in Nov, my contract ended and I decided not to upgrade my phone, just to have the SIM only contract. I was sent a new SIM but told it was just a spare one and I didn't need to put it in my phone?!!
The phone has been working fine till a few days ago, so I'm now wondering whether there's been a delay and now my old SIM has been deactivated? Can you confirm if I should now be using the new SIM and will that mean my mobile number will change again??
