[Xperia Z3 Q&A, Help & Troubleshooting] RockStar2005:
Hey eebovipe,

I'm really sorry to hear about that.

Honestly, I'm shocked that you tried my suggestions and nothing worked. So you did the Sony PC Companion thing, and everything else without any skipping? I have to ask that.

When you created the new APN option, did you make sure to select it after saving it? The MMS issues are caused by the APN default not being the best one, not using Textra, and leaving VoLTE enabled. You also have to make sure to enable MMS in Textra, etc. When I do the iMessage thing, I don't get the text to myself in the stock app, but I do get the message I think in Textra though. That step is only to fix the iMessage issue IF you're even having it like I was. I guess doing that (according to T-Mo Store rep) somehow re-teaches the phone how to handle MMS properly. Doesn't make much sense to me, but it did work. Now I don't miss any iPhone MMS texts, even when iMessage is on.

I've only done rooting once in my life......last year on my HTC One M8. I'll prob NEVER do that again though b/c it's a pain in the a$$ and I don't like having to manually monitor everything. It was cool for a little while but then it just becomes a hassle IMO.

I would go through all the steps one last time, just because it can't hurt and something possibly might've been missed the first time around (happened to me when I first tried to root last year and failed. Had to try a few times 'til it worked.) . I mean, there's a lot of ppl who got the Z3 who didn't have ANY issues at all from what I've seen. Or the only one they MAY have had was that they had to replace the stock texting app with something like Textra. I wasn't as lucky unfortunately, but after some research and trial & error, I got what was contained in my main posting. I'm not happy I had to go through all that, but my phone does work flawlessly now, and I wouldn't trade it for anything else out there now, even the newer ones.

Wait, you paid for it all upfront, and got it from T-Mobile directly? I only do the monthly thing b/c there's no difference in price that way, and I usually don't keep my phones the full 2 years anyway. I would complain and say the phone doesn't work and you want a different phone. If they say no, ask for a supervisor. They can't make you keep your phone if it doesn't function properly. Also, do you have "JUMP!"? If so, and the complaining approach doesn't pan out, I'd wait until you're eligible then just switch phones then. You could go with the Samsung Galaxy S6/S6 Edge, or else the HTC One M9. I'd personally go with the M9 only b/c I CAN'T STAND physical home buttons. lol And the one lone speaker on the back doesn't fly well with me either. M9's an even better phone than the already great M8 was, and I wouldn't need to root it b/c the stuff I couldn't get last year on the M8 are now avail on M9 (improved audio quality provided by Dolby, the option to choose which gestures you want instead of being forced to use all of them or not, etc). The camera on the M9 isn't as great as the Sony or Samsung ones, but the trick there is to create a manual mode option with HDR enabled as the default. Then the quality will be much better. My sister is about to upgrade from her S4 to the M9 any day now. If you get the M9, let me know and I'll send you what I have on making the camera optimal.

Let me know what happens. Sorry again about the problems you're having. I know someone who has the brand new S6 Edge and said he's having some MMS issues too (prob just needs Textra), so these things don't just happen to Sony phones. The battery/power saving options on the Z3 STILL beat out the newer S6 & M9 IMO b/c they can't whitelist apps. So like when you get group MMS texts when Power Saver is on, it won't automatically download them, so you have to do each one manually. On Z3, I white list my text app so everything comes through right away (as mentioned in my main post).
