Welcome to AC!
Has this been an issue for a while or is it recent? Have you gone to your provider and asked for a new SIM?

I've done both of those, and even got my phone replaced by straight talk themselves. It still does it.

I also have a Straight Talk Samsung Galaxy Grand Prime and have had to replace the SIM card 3 times now... for no reason it keeps going out.. gives me a message ... Invalid SIM card... can any one explain to me why? and what can I do to fix this problem..

Welcome to Android Central! It could be a problem with the phone's SIM reader. Since others have mentioned this issue, perhaps it's a known issue with that particular phone. Is it still under warranty? If so, contact Samsung.
