Can't use my pocket pc as a mobile phone

Hi there, I have a pocket pc Dopod 828. I've been using it as a mobile phone for almost 1 year. Recently it's not recognizing my SIM card anymore, and a message " invalid SIM card" shows up everytime I try to switch it on. I guess the problem is not with the SIM card because I'm using it in another cell phone. I also tried to put my wife's SIM card on it and the same message came up. Can you help with this one? Thanks in advance, Best Regards Ric777.

Hello Ric777, I would suspect the mainboard of your pda at first. But for the begining you should try to clean the contacts of your sim slot and check to see if all of them connect properly to the sim card. If all of them do connect properly, my second gues would be that the pda doesn't power on the sim card. Like memory cards sim's need to be powered first in order to work. Most pda that have this problem fail to initialise a sim because they can't suply the 3.3 or 2.7 volts needed due to a hardware mailfunction. However this test should be runned by a service center, they will have to dissasemble your pda in order to check these. In your case, you can make a hard reset and check the sim card pins in the pda. If this doesn't help, you will need service assistance. I'm sorry for not being able to help further. Good luck.
