HTC 10 doesn't receive all texts

Hello there @suzdvm!

My apologies for the issues you’ve been having with your HTC 10! That’s a pretty cool phone, so we want to do all we can to get it working in tip top shape!

I would suggest starting out with our Online Troubleshooting Tool for Messages. This will give you a lot of great fixes to try!

I could not have more exactly the same problem as suzdvm. It's getting worse and becoming extremely frustrating. I sometimes get long texts and sometimes don't. The problem seems to be coming mostly from iphone users sending me texts. I just got my first text that combines part of the message sent with a segment from a months-old text from the same user. 

Any other suggestions? The link provided doesn't include the HTC 10.

Literally created an account for help finding a solution to this problem.

Thanks.

@suzdvm, @gwobbles I bet your APN settings aren't quite right.

Typically, shorter and non-group, non-media(pics, etc) messages will come via regular SMS (also shorter messges, non-multiples).

Longer messages and the above use MMS, which require APN settings to be "just right".

Here's the setting page for most devices: https://www.att.com/esupport/article.html#!/wireless/KM1062162

Thanks for the reply. I found the Access Point Names menu and made the recommended changes on the linked page. There were three additional Data Settings on my phones list: MMS protocol which I left at WAP 2.0, APN roaming protocol which I changed from IPv4/IPv6 to IPv4 recommended for APN protocol, and APN enable/disable which is set at APN enabled and cannot be changed.

I hope this works. Because this is an intermittent problem, it may take days of receiving texts before I'm convince that this solution has worked. I'll try to get friends to send longer texts which seem to be more likely not to be received to test the fix. 

Thanks again. Fingers crossed!

Sure, have somoene send you a text with a bunch of "text" and a picture, which will surely overflow the "single SMS limit".

This should be a good way to test it, quickly.  Or have someone paste in a small document, into a text, again a good way to overflow it, and test.

@suzdvmAssuming it works, please come back and mark it as solved, so I can tag it, and the next "stuck" person will hopefully find the thread.

Thanks.

Actually, my phone receives some really long texts (well over 300 characters) at times with no problems and pictures with a lot of text. The missed texts occur intermittently with no obvious pattern. And the phone will sometimes receive the text that was missed if the sender simply resends it.

@pgrey I will definitely mark "Accept solution" if this works.

@pgrey Sorry to report that the first long text sent to me as a test didn't come through. When my friend resent the original text that I failed to receive, it came through fine, all 359 characters plus several emojis in a single text. This does not appear to be a problem with my phone's settings but with either my provider's (AT&T) receiving it or the sender's provider transmitting it (though the texts I've missed come from multiple providers).

Also, when I tried to send a screenshot with the new settings, it failed twice. Once I switched back to to factory/AT&T APNs, the screenshot sent right away.

Back to the drawing board.

@gwobbles I know how frustrated you are. I'm at wit's end. As the solution offered above didin't work and our local AT&T store is for sales only, I will try chatting with AT&T customer service online to see if they can offer any soltuion.

This wasn't a problem during the first two months I had my HTC 10 but is definitely getting worse. What is your experience? I love the phone and am hoping it's not a device problem. A friend with an iPhone is experiencing occasional missing texts too.

Thanks for the tips @pgrey. I had the same differences as @suzdvm in the APN settings, which I changed as well. Looks like those didn't work out for you so it must not be the source. 

Some other searching led me to wiping the Cache Partition which you can do with these directions. I had the same issue as the original poster in regards to performing the wipe. I haven't tested extensively but I have gotten some longer texts and everything looks promising so far. As you've stated before the problem is very intermittent so I'll give it a few days more testing before I feel a little more confident the issue has been improved/solved.

Good point @gwobbles, I'm more of a Win Phone guy, so I don't always default to the "cache partition wipe", as many others here do (give me some more time in the forums ;-]).

@suzdvm, This is good thing for you to try as well, do you know how, or would a pointer help? *Most* android implementations involve holding down the power and volume-up keys, at reboot, and then a couple of selections from the console screen to do the actual wipe.

The flush is a likely candidate in this case particularly, since it can have bad DNS and other types of entries, even possibly cached APN settings, and flushing this would basically "force" your phones to restart with the latest settings, for all messages, moving forward.

I sort of doubt this is an AT&T thing, it's possible, but pretty unlikely, as we'd be seeing an inordinate amount of posts, if it were pervasive.  Android is a great OS, but it's highly "customizable", and as a result, it can be "corruptable" as well, just like any OS, none are perfect, period...
