Suddenly in the last day text messages from regular contacts are not appearing. Mostar iPhone users to my knowledge. I am receiving some text messages. I checked all my settings and everything seems to be normal. I can send text messages to everyone.
Check troubleshooting steps here, If you can't send or receive messages on your iPhone, iPad, or iPod touch - Apple Support
If you are sure they are iMessages that you are not receiving, then go to Settings>Messages and see if iMessage is activated. Also check to make sure that you have an active internet connection, either wi-fi or cellular. Cellular data would be needed if you are not on wi-fi to be able to receive iMessages.

Not all of my text messages are being received. Checked all my settings everything seems to be normal. Receiving text messages from android phones and not iPhones, not 100% certain of this.
