I havent tried it yet, but it seems very logical.

Your signal strength is only thru your antenna. If your SIM does not have a good connection, your phone is not going to work.

Several people have add a piece of paper like a post it note to the back of the sim card to make it fit more snug but I do not see how this can help a weak signal.
