Okay so I bought this unlocked slvr l7 phone from ebay. Once I got it I took my mother's nextel sim card to test it out and I could swear that it worked. Though after I started using t-mobiles prepaid sim cards it stopped funtioning. I can't get it to connect to a network with my mothers sim card. I have started reading some post, and to what I understand, nextel uses a different type of technology and not gsm. So It could not have been possible for it to have worked with my phone. But I remember that it did. What can I do? Could anyone kindly assist me with this problem?
The SLVR is a GSM model. It is not compatible with the iDEN network. It may have said something like "Emergency calls Only" or something like that. -Jay
Well yes that's what it reads right now. Though like I said I could swear that it worked with my mother's nextel sim card, because I made a call to my home. I don't know maybe my memory is wrong Anyways thank you for your reply, I 've asked this question in two other forums and did'nt get any replies. So thank you again.
To back up what Jay said, the fact that AT&T, T-Mobile, and Nextel use SIM cards is the only similarity between them. Nextel uses a completely different network technology completely incompatible with AT&T and T-Mobile.
