Z3 compact doesn't connect to network

[reeta]

Hi. About a week ago my z3 compact stopped making and receiving phone calls and texts while the mobile web was still working fine. I thought the problem was with the service provider and they changed the old 3g sim to a new 4g sim. Now also the Internet has stopped working and still no calls / texts go through either way. The Internet still works with the old 3g sim.

I've tried manually connecting to network (3g and 4g both) but no luck. Naturally the phone's been rebooted a couple of times.

Anyone had the same problem?

Thanks.

What if you get a brand new NANO SIM card?

I have two brand new nano SIMs, neither of these connect

Contact your local carrier/network and double check the APN settings.

APN settings are as they should be @uliwooly

This is what I would do, I would contact my network and verify that they have activated the new SIM card. The old SIM card should not work at all.

The new one has been activated and the other new sim I have is a pre topped and should work instantly

I've now done this. Earlier when I had the SIM in phone it did not show my own number, now after two reboots the phone shows my own phone number but still won't get service.
