I know it’s a lot to read we have what now?? 22 pgs of this topic now and growing...even though people are slightly seeing different things, the common denominator here is the iPhone...I can’t rule out the carriers, but the issue with not just MMS, but single one to one SMS txt messages from Android users that can’t be retrieved is the MAIN issue here. Android users are seeing are messages and replying, but iPhone users can not retrieve it!
They're also has been some work arounds but it’s not been 100%.
After taking some recommendations from some of you, I’ve been able to fix this on a case by case basis..My personal experience has been as such; new android phones no issue..Older android models still an issue.
The fact remains that I still believe this will have to be a collaborative effort with the carriers and Apple ASAP!!
