I do not get all of the texts that are sent to me, and the problem seems to be especially bad for texts sent to me from an iphone. I have verified this many times by comparing phones with the senders and viewing all of the texts they sent that I never received. Sometimes, their messages get broken up into 5 or 6 different text messages and delivered in a strange order. I've updated the profile, prl etc. many times and I have done a factory reset. The problem persists. Please help!
Definitely sounds like a frustrating and weird situation. Are you able to insert your SIM in another phone and see if the problem persists, this helps us better identify whether it's a SIM or phone issue. Let us know how you go.
