Blackberry Z10 on Straight Talk Prepaid

Quick look at Z10 running ST’s At&t network

I have my Blackberry Z10 running on Straight talk's Prepaid service (ST BYOP AT&T Sim Card) .Calling, Text, and DATA work. Can't Send/Receive MMS yet.

When the Z10 launched, the BB10 OS did not allow you to modify the APN settings. When AT&T released their 10.0.10.116 update for the Z10, it allowed the APN settings to be modified under the Diagnostic Screen Or Engineering screen. Below you can find the Thread from the Crackberry forums where I found how to access said diagnostic screen and settings.

AS OF JAN 2013. Straight talk no longer sells Sim Cards that work on the AT&T Network, Only sim cards that make use of the T-Mobile network. Ebay maybe you source for the AT&T variant. This method should work for the Current Sim Cards Straight talk is selling, which use the Tmobile network.Instead of "att.mvno" it should be "wap.tracfone"
