just got a verizon BB 8830 (without contract) from ebay, which i am very new to this phone.
I was told that this phone can used any GSM card while overseas.
So while in asia, I was trying to use it by inserting a local GSM card. but the screen indicate 'Invalid SIM Card'
Is there anything that need to be done?
Can anyone plse help. I got this phone for purpose of travelling, thanks
