14th July, my phone went dead with no service at all.

What is your phone, can it actually receive a 3 signal? Is there 3
coverage where you are? Do a network scan and see what is out there.
Is it Android? Try Network Signal Info from Kaibits Software, that'll
give you all the gory details.

Forget all that. Just found on the TPO site that if you are without
service since the 14th you need a new SIM. There is an online form to
complete. IIRC it's in the Help section and related to Network
Status.
