I just tried a Globe Tattoo, brand new. Installed the software, all went fine.
It showed in the status bar bottom left 3G Globe, with 98% signal.
Clicked "Connect", and its stuck for 30 seconds at "Authenticating", then error.
Switched it to GSM, and all works instantly.
Back to 3G, all is bad again.
Tried another sim, same story. But, both sims work in the cellphone via 3G...
Any suggestion?
