What is the path where GoSMS stores the SMS messages
SMS messages are stored in data/data/com.android.providers.telephony/databases/mmssms.db. If you can't see it in your root explorer (or it is to small), try rebooting your device or simply - connect your phone to the computer and copy that file (using e.g. ADB) on it and I'm sure you will be able to read it properly .
