I have an iPhone 5c. I am failing to receive sms from a number of people (non iPhone users). Although, I still successfully receive sms from others. I called tech support and reset all my network settings, to no avail.
I looked at the online sms log for my line, and these numbers are not showing up as incoming to my account either, although these people have shown me proof of sent messages. Could this be a porting issue? The weird thing is, I've successfully sent and received messages from these people about a month ago, same phone same line. Please help.
