can a cingular gophone sim card work in any att/cingular cell phone?

[twilightobsessive]

i doubt it. go phone sim cards are especially for the type of phone it is. and the blackjack and blackberry curve are smartphones, the formatting is completely different.

i have a cingular gophone simcard and may use it in a blackberry curve or a samsung blackjack from att
will it work?
ive used it in a blackberry pearl and a lg shine
so maybe..
im just making sure

You have to Unlock Blackberry and SAMSUNG phone Unlocked from network lock.Otherwise you cannot use the Cingular sim card...Your Blackberry Pearl and Lg shine are Unlocked Phone i think...So get the Unlock code from the ite for Blackberry Phone and Samsung Phone at Mobile-unlocker.com/blackberry/rs2wp8/ and unlock it.Then use any GSM Network Sim card.
