pin code not recognized by unlocked treo
Posted on 2008-10-14
I have a refurbished Treo 680, unlocked by AT&T. I can put in another ATT's sim card in there just fine. However, when I insert a sim from a different provider and enter the PIN code it tells me that the pin entered is not correct, even though it is not true. Although it tells me I only have 3 tries to enter PIN, I can do it as many times as I want and nothing happens. The sim does not get locked. The same sim card works fine in another Cingular-unlocked phone.
Any suggestions as to what I can do? The ATTY people did not help much. Told me they can not work with other provider's sim cards.
