I've had T-Mobile for over a year and I know their service is not stellar but it works for me (also don't want to pay more for service). I've had the 6S since last year and reception has been fine. Ever since I got the 7 a couple weeks back, people have told me they need to call me twice in order to reach me. The first time it rings and goes straight to voice mail (I have no record of receiving first call). Second time it actually goes through. Sometimes people just call once and assume I didn't pick up. I don't know why this is happening now, but I think:
- It can be my spigen case (its thin), but it shouldn't interfere with reception.
- Maybe because it only has two antenna lines instead of four?
- Possibly the Jet Black finish?
