I'm on my 2nd HTC One X plus in less than 2 weeks. The 1st phone worked out of the box, then 4 days (could have been sooner) inbound calls stopped reaching the phone. Callers got ringing then a switch to a busy signal or a message that call couldn't be completed. Nothing reached my voicemail and the phone showed no missied calls or voicemails. AT&T switched out the sim, the phone then worked for 2 days and again stopped receiving calls. I could receive texts and call out. Went back to ATT, received a new phone that worked for 1-1/2 days and now today is not receiving calls. It either rings (8-10 times), then goes busy, or rings 2-3 times and gets a "unable" to connect message. I really like the rest of the features of this phone, but if it won't receive calls it does me no good. Is anyone else having this problem or had it and found a solution before I return it again? Thanks.

I have been having this issue since last 2 months. I have done everything as per AT&T's guidelines but nothing worked. (changed SIM, changed phones, factory resets) Even after all this AT&T is not ready to admit its fault. And they are treating this issue as "User Issue"
I have posted on AT&T's facebook page and I seem to be getting responce from AT&T. I also received a call from AT&T public relations this morning. If you all can comment about your frustration on the link provided below and describe that you are having the same issue, we can get good visibility and hopefully solve the issue. If not, we can include media like Engadet, The Verge and others to get media coverage. Please comment your issue on the link below. Thanks a lot in advance.

I haven't visited the forum for few days but the *#*#INFO#*#*, USA bands seems to fix the issue for me as well. Now the phone rings almost immediately after 1-2 rings. Lets see how it holds for me.

I've tried the USA bands numerous times and as far as I can tell, it has absolutely no effect on my phone. Is there any way to actually tell if the settings on the phone have actually changed?

I have tried all of the above steps which did not help the problem. I switched the user to a Samsung Galaxy S3 and the missed calls continued.
The error is an AT&T LTE issue with Android 4.0 and higher phones. AT&T have been aware of the problem since July 2012. The trouble ticket the RF engineers have state its due to cs fall-back failure.

They did a warranty exchange on my HTC One X+ for this issue, and the phone they sent me has a blown ear speaker. Calls are very low and have static. They are sending me another one but I am extremely angry I have to deal with this broken phone while the other one gets here. You'd think I wouldn't get a broken phone as a replacement.

Well, the radio band "fix" didn't actually fix anything, so I am trying another suggestion: Changing the APN. You lose LTE so is a less than optimum solution for a lot of people, but I use mostly wi-fi so I don't care all that much.

You can prevent using LTE that way, or at least get rid of the LTE icon but none of the ones I tried solved the missed call issues. The only way that I can get consistent calls is when I'm on Edge- "E" displayed and none of the numerous APN's I have tried will force Edge use. Keep us updated

The problem of course is that you can never really be sure that any particular solution works. Absence of evidence is not evidence of absence.
