Sprint 9930 stuck on GSM, doesn't shows EDGE

I just bought 2 BlackBerries 9930 from Sprint USA, i got them to used them on Mexico. they where unlocked out of the box. Since i just put my SIM on them and they connected perfectly to Telcel Network. After a while of using them they went to GSM and wont change to edge or EDGE.

Has anyone bumped to this issue? Any solutions.

I know the compatibility for their network Sprint/Telcel. Will only connect to EDGE.

I already check the Mobile Network.
Data Services: On
While Roaming: On

Mobile Network: Telcel
Network Selection: GSM/UMTS
Network Mode: Already tried 2G, 3G and 2G/3G

Still only shows GSM on both phones.

Please help. I spent a lot of $ on this phones. And they are giving me a really pain in the %$#.

Thanks!

Try doing Options > Device > Advanced System Settings > Host Routing Table > Menu > Register Now.

Also try updating the PRL in the mobile network options.
