I've got some Cingular (and one ATT) phones I managed to repair.
However I would like to test them making a couple of phone calls. The problem is I don't have a Cingular account.
With Sprint CMDA phones you still can call cust svc even if you don't have an account w/them. Same with Verizon.
I am kind of new to GSM phones, so I may be mistaken, but even with a blank GSM card inserted I can't call anybody. The only exception is an emergency number (cellphone says that) which I am not sure if it's going to ring at a 911 number.
The cellphones I have are locked as far as I know.
Could I perhaps sign up with one of those prepaid accounts that CNG offers, so I could use the GSM I would activate with the phones I already have?
Have they to be unlocked even if I want to use a prepaid service GSM card with them (even a Cingular one?
Any other links I can find more info on this subject?
Thanks a lot,
