I have a Ntt Docomo Panasonic P-04C and i have Tmobile carrier and i install Hypersim card to it but it cannot find the Tmobile network. I put network search but it only finds At&t network which is strange because i don have that carrier. I don understand why its doing this. Do i need to do the CPR on the phone because i had previously used a 3g phone. Please any help!
