I have a GSM Palm Pre and im using it on Orange Network with Pre-Paid SIM Card that i charged with credit when i need to.
to Check my credit i type *155# then hit Dial. this works.
but requests Like *777# (to access self services) and Call Back requests didnt works on Palm Pre!
Dose anybody have a patch to correct this or makes what called USSD requests on Palm Pre(GSM)?
