I flew a round trip from DFW to IND a week ago. I followed the directions to set up my T-Mobile wifi: Airplane mode was on; calling over wifi was on. However, I still could not send and receive tests. After I landed and went back to mobile tower service, I got a bunch of texts. However, it was obvious that several texts were sent while I was on the plane that I never received at all (even after landing). It was a group text, and people were commenting on posts that I never got. That is not normal for me either.

BTW, I have sent and received texts and calls over wifi on this phone before, and I was able to browse the internet. The only place it hasn't worked was on the flight.

The person sitting next to me bought the wifi, and she couldn't send or receive texts, ether.

Anyone else have this problem?
