    My Pantech C300 is not currently hooked up, however, I got my cousin's SIM card and tried to use it on my unit. When I inserted the card it read "change SIM". After attempting to unlock it several times, the unit blocked me out. Tried contacting the previous service provider but they can't assist me with this. Don't know what to do. I recently bought the unlock code for the unit but now I am not able to use that one either.

Whenever I Turn On My Phone It Says That The SIM Card Must Be Inserted, Even Though It's Already In.


The SIM card may not be making proper electrical contact in the cell phone.
Try removing the SIM card and cleaning the SIM card contacts and the SIM card contacts in the cell phone with methylated spirits. Then replace the SIM card in the cell phone.

Pantech c300 will not get service anywhere


Might be that there are no towers on the correct frequency for the phone to work where you are. If for some reason there are no 850Hmz or 1900Mhz towers in the area the phone won't work.
