Anyone using this on AT&T? - Sony Xperia XZ2 Compact Questions & Answers

I have the duel Sim version and best I get is H+. I have never seen Lte or 4g displayed on my screen. I'm new to Sony phones so I don't know if the icon for Lte or 4g just doesn't show up or what. I came from a 4g phone on AT&T and the nano Sim is a 4g Sim.

Good news for anyone other then myself that was having this issue! Out of pure curiosity i took my wifes sim out of her at&t phone and swapped it with mine just to see what would happen, and HOLY SH*T i have LTE! So knowing it must have been my new sim causing the issue I took it and put it into my wifes phone and BAM it showed as LTE on her phone. Then I put both sims back into their origional phones and SUCCESS my phone now shows LTE. No freaking idea what this did exactly and how it worked, but somehow it must have affected the new sim I obtained from AT&T. How the people at the AT&T store and techsupport didnt know this is beyond me. Anyways cheers!

Not sure....what phone you have? The t989 does not do LTE.
Just so you know. Not sure about the sim cards tho.

This phone/sim does not come with the supported hardware for lte , so if you do get a new phone supporting lte just go down to t-mobile and say you need a new sim card they usually don't charge unless you get a rookie or an @$$
The sim card itself is lte enabled but the Hercules doesn't have the hardware, they did package late software in the latest update but it won't be useable until they restructure their entire tower system, and u need to have a model built after apr2013, some ppl in the midwest have seen lte already but like I said u need to be in a restructured zone with a t989 built after apr13', this comes from a tmobile tech rep....although realistically this phone is capable of 42mbps anyway with regular 4g so late isn't going to be that much better in its early days..

I was planning on getting new LTE phone so that's why i was wondering
when you get a new LTE phone they will swap your sim card for a new one but tell them you want to keep your old one just in-case or they throw it away lol

T-Mobile on AT&T S3

I know there's loads of questions and threads about T-Mobile on a S3 but I've been dealing with this issue ever since my girlfriend gave me her old AT&T S3. I signed up on here just now because I couldn't stand trying to figure it out myself anymore.
I've also looked at all those threads and for some reason they all seem to have an opposite issue of what I have. To my understanding, areas that aren't re-farmed will give you 4g LTE and 2g (edge) but no 3g correct?
I get the opposite of that, I get only HSPA+, HSPA, rarely 2g and never LTE. The part I don't understand is why I don't get LTE. My Brother is able to get LTE with his T-Mobile LG G2 so LTE coverage should be fine in my area.
I ended up finding out that T-Mobile requires a newer sim card to work with LTE and I was using an extremely old one that I got when smartphones basically just came out. (I cut it into micro shape) Today I just received my new sim in the mail, popped it in and it showed LTE with 4 bars but I couldn't do anything because I haven't activated it yet. Once I got it activated it went back to HSPA+.
The weird part about this is that if I restart my phone sometimes it'll show LTE for a couple seconds but it'll say "no service" then proceed to go back to H+.
I'd like to at least know someone else gets the same thing because it's been driving me crazy and it seems like I'm the only one having this issue. I've literally been trying to get LTE on this phone for about a year now.
If someone can try helping that'd be cool, thanks

[HELP!] Getting my Verizon S4 working with T-Mobile

Hey guys! I'm trying to get my Verizon S4 working for my wife on T-Mobile! She got the LG G3 last night and because she's so tiny, it's like a tablet to her!
Anyways, the Verizon S4 is rooted and is still on original MDK firmware. With that said, I'm not too sure exactly which steps in your guide apply to our situation...not having safe strap and all.
With changing the APN settings to match up to my phone (LG G3 on T-Mobile), and inserting a T-Mobile 4G sim card, I'm able to get calls and SMS working over WiFi on the S4...that's it though. No mobile data seems to be coming through. Her mobile signal icon in the status bar keeps switching back n forth from E to H for some reason...but no LTE or 4G icon.
Anyways, is this something anyone thinks they could help with? Or do ya think we're screwed? My sweet wife would be eternally grateful if someone could help to make this happen!!
EDIT: haha, my signature will be changed if I'm able to get this working for her!
Aren't you missing something here? Verizon is CDMA, TMo is GSM. I don't see how you can get cell coverage to work unless the phone has dual antennas.

Many newer CDMA devices with LTE support have gsm radios as well, that includes sprint and Verizon..
To OP, you may have better luck searching the Verizon forums if nobody replies here

OnePlus 5T LTE AT&T

Is there anyone out there that can assure me the OnePlus 5t i am getting direct from them will connect to AT&T LTE all bands? I am porting my number after I pick it up from FedEx and if this issue is still ongoing I will not pick up the package but have it sent back. I don't want to port my number from another carrier to AT&T or I will be stuck since I am coming from Verizon.
Thanks

You won't have any problems with GSM carriers. OP5t supports all bands for those. I'm using mine on ATT in New Hampshire and it works normally. On some custom ROMs you might need to play with the APN a bit but on stock it worked fine out of the box. VoLTE and Wifi Calling will not work, even if you enable the settings with a Magisk module, however, so don't count on that.
Yes. I can also attest, works just fine on AT&T LTE.
Works fine on AT&T

Works fine on ATT, but be prepared to deal with ATT support as this device isn't officially LTE certified. When you give ATT your IMEI, you will likely be limited to a HSPA+ connection and see H+ instead of LTE on your status bar. My OnePlus One worked just fine, but I needed a new sim for my OnePlus 5T and took over a dozen calls to ATT support to finally actually get LTE on my phone... but as more and more people get their phones activated on ATT it will probably become less and less of a PITA.
LTE+ actually shows several times for me on the 5t, but as others have said LTE works fine. I didn't have any problems getting LTE with mine. Switches sims and pulled LTE immediately

Just take the sim card out of your old phone and put it in the 5T and you should get the same service you got before

Woking fine on ATT LTE for my 5T. I popped my sim from my 6P and put it in the 5T. LTE came right up. As others have mentioned, I've read that the issue is that ATT is a prick about unlocked non-ATT phones. Just give them the IMEI of your old phone when porting over and it should be fine.
This is my experience during the last week:
Went to the ATT store , Clinton, Connecticut, bought new sim and activated my brand new 5T. Only got H+. I have an extra att phone, I put the bought and activated att sim from the oneplus in it. But I only get H+ on that phone. So I plan to go to att store and ask them to activate lte on that old phone. Now when I put the sim back into the oneplus . All I got was H+. In other words, what imei will it be for my oneplus? I would assume it will be the old phone imei since the sim was activated on it. I am kind of one track mind about lte, because I had trouble sending pictures over H+. I don't know why I seemed to have problem when other oneplus owners seemed to fix their lte easily. I have spent hours at the ATT store and the tech and manage Mike swore that they cannot help me. They referred to ATT tech support because my 5T is not recognized by ATT network.
PS. I took the 5t to the att store and bought the sim from them. They activated the oneplus imei so that might be the original problem. I really need to fix this.
AT&T can fix it. It's a HUGE pain, but it can be done. Do you have another phone on your account with the same size sim and LTE? My argument to ATT was this:
My wife has a S7 and gets LTE coverage. Phones side by side, the 5T states H+. I take the sim out of the S7 and put it in the 5T and boom LTE.
Support finally did something with the IMEI and ICCID on my account. After two reboots (no idea why two boots unless whatever he tried first didn't work), I got LTE with my sim on ATT. Don't bother with an ATT store as they have proven to be completely worthless. It's not an 'uncommon' problem. Keep contacting support until you get someone who can help you.

I would have done that, but the OnePlus One has a micro sim and the OnePlus 5T has a nano sim.

That was exactly my problem. I cannot believe the ATT store cannot and or would not fix it for me. Anyway I ordered a new sim for my number directly from
ATT and it worked for me. As the ATT tech support said the ATT store sim was for the wrong ICCID. Hope this helps someone.

55mb/s consistently on Straight Talk (Using At&t's towers) in Chicago. Shouldn't be a problem at all. Verizon on the other hand

T-mobile dropping and data on edge

So i purchased straight talk form walmart and it came with an att tmobile and verzion sim card. I always wanted to try tmobile and have noticed their strives to make there network better over the years so i decided to activate on the tmobile sims card. The problem is the signal drops and when it does come on its either G or edge. how can i fix this. Anybody notice this happing. Its a shame it really is.
