Question
QUESTION: I have go a PDA from china i have been using it and its worked fine but a week later its saying my sim card is invalid. But my sim card works in other phones.
ANSWER: Your SIM is not invalid, the phone is likely defective. Take the SIM out and put it back in and see if it works. If it doesn't, it is likely because either the SIM is not properly seated in the device or because the device is broken. I hope this helps. Thanks. DebiN

QUESTION: I have a blackberry curve 8310 and the internet dont work how do i get this to work please help......
The only way that the internet will work with your BlackBerry 8310 is if you add a BlackBerry data plan with your carrier. BlackBerrys cannot be configured to work with MMS or the internet. You have to have a BlackBerry Personal or Enterprise Data Plan added in order to use the internet with a Blackberry. They access a server and there are no manual configurations for this. I hope this helps. Thanks. DebiN
