I recently bought an unlocked HTC G1 phone and it was sent to Nigeria,but it wont recognize the Sim say NO SIM CARD

G1 is an american branded phone ( GSM 850 / 900 / 1800 / 1900) , It wont work on all service providers across the world .. You might want to put another service providers sim card ...

I am in India can u please inform me as to which kind of of connection can the PDA work with it is CDMA or GSM and i want to know how to unlock the hand set to make it workable with that network

Many Pocket PC users including me have been using i-mate Pocket PCs in India with our local GSM SIM cards.
I don't think you need to get it unlocked to make it usable in India.

what phone company was the phone using before you unlocked it (sprint) ?? that slot you are looking at is probably a memory card slot not a SIM slot. everything im reading says that phone is not a GSM phone aka it doesnt take SIM cards

The carriers who use non sim phones for their network are most likely to use a CDMA 450Mhz Network. Most phones with a sim slot will work on GSM 900-1800-1900 Mhz bands, with their subdivisions (like 850-950 domain, 1800-1850). A phone with a sim card uses a RF module tuned on a specific range of frequencies. The major ones are GSM, CDMA and UMTS (HSDPA included). There are phones with support for GSM + UMTS - most 3g phones available on marked. In your case, a GSM HTC touch Dual will work on gsm networks. For verizon or other cdma networks, HTC produces a CDMA version of the Touch Dual. If you have the gsm version (the one that needs a sim) you should use it on gsm carriers.

Hope this helps.

Can't use my pocket pc as a mobile phone

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.
