MicroSIM swap from iPhone 4 to HTC One X - texts from iOS devices still go to SIMless iPhone
I have been using an iPhone 4 since it came out, but just recently received an HTC One X as a gift. Swapped the SIM, and the HTC works great. However, texts from friends with an iOS device are still sent as iMessages to my SIMless iPhone. I've tried deleting the text "threads" on my HTC and on a friend's iPhone, but still her texts go to my iPhone as an iMessage regardless if she sends the first text or if she replies to a text sent from my HTC.
Before I began using the HTC, I had to call AT&T to modify my account. The CSR told me that technically there should not be any problems if I just switched the SIM back and forth between the phones, but that towers would recognize my HTC as an iPhone. The iPhone 4 was kept as my "phone of record".
Now, I am thinking I need to call AT&T and have the HTC listed as my phone. This should then remedy texts being received as iMessages to my iPhone?
