Lately, i can’t receive some text messages from a friend of mine. I searched about it and it says in the google that resetting your network is the best thing to do. And after i did that, it become okay but a few days later , i can’t receive text messages again

In my experience most of the times this problem is related to iMessage, and not the sms part of messaging. Try disabling iMessage for a while, and see if this fixes it.
