I am not receiving text messages from specific people - why?

Hi believers76,

Thanks for using the Apple Support Communities! I'm sorry to hear you are having these issues with your iPhone. If you are generally receiving Messages alright, but are having issues receiving them from specific contacts, you may want to double-check to make sure that they haven't accidentally been added to your Block List. You may find the information and steps outlined in the following article helpful:
