8830 and GSM SOS

[damienpek]

hi sorry i know bb8830 is old, but i recently bought it off ebay, unlocked and once from Sprint (US).

i have checked with mepd
ID 8965.........1001
Personalization:
SIM: Disabled
Network: Disabled
Network subset: Disabled
Service Provider: Disabled
Corporate: Disabled
(this means its unlocked rite?)

i m using SINGTEL carrier in Singapore and running on GSM 900/1800 frequencies, but my SIM card in my BB always show a red SOS instead of signal strength. when i choose "GSM", "MANUAL" under Manage connections/ Mobile Network Options, i can find 3 different service providers in Singapore but when i choose SINGTEL, it will become a SOS sign again.

Can someone please advise?

Perhaps the carrier does not support the GSM frequencies? Or it is not properly set up and activated by the carrier?

the carrier definitely carries GSM frequencies. and i have checked n its in accordance to the european frequencies.

does anyone know whether where i can find any instructions for settings i have to key in?

thanks alot
