Was having an issue with the phone losing signal when in poor reception area. Do I need ATT to activate phone with imei of xz1 or in order to get LTE do I need to have a previous att branded phones imei on the sim card? Is there any ATT bands this phone doesn't support? Just don't know why phone says no service when it is in a bad reception area. My iPhone 8 works perfect in the same areas.
Use an IMEI of a LTE AT&T phone if possible. If you give AT&T the IMEI of this phone it won't be in their database and it will be provisioned as a 3G device at best.
Do you have any issues with it losing a connection when there is poor cell phone reception?
****, this phone isn't functioning with AT&T LTE? That's a problem... Can anyone else confirm?
I have AT&T. When I got the phone I called them, gave them the IMEI and they did whatever they need to do and my phone works with LTE.
I had previously contacted their technical support before getting this phone to verify that band 12 would work as well.

Log into your AT&T account online and see what they have for a device for your number. It works fine on AT&T LTE but I have had issues for years when giving them the IMEI of my Sony phones. Maybe they have joined us in the 21st century.
So, from what I have been reading online and asking my IRL friends, it seems like AT&T doesn't exactly let devices that aren't sold by the carrier automatically have provisioning for LTE and LTE+. You have to call them.
Only negative in general is that VoLTE and Wi-Fi Calling cannot be enabled as a company policy at this time on phones not directly sold by the carrier. Even the Google Pixel 2 can't get VoLTE on AT&T.
...Anyway, solution so far is to call AT&T via 611 or from another line at (800) 331-0500 and ask to "Activate my SIM"... And then ask for an agent. You'll need to give them the IMEI of your phone.
Only then, after you reboot your device, will your phone be provisioned for LTE.
Is this all correct??
I haven't had success giving them my Sony IMEI. I have a carrier version LG V30 and when I bought it, AT&T gave me a new sim. I pulled it and put it in my XZ1 and I have LTE.
As augie7107 mentioned, the trick seems to be getting an IMEI of an AT&T phone attached to your account and sim and you can get LTE on other non-branded phones. The sim I've been using has been the same one I've had since a launch day AT&T iPhone 6. I've used the sim in a number of unlocked Android and Windows phones without major issues: Nokia 925, Moto X Pure, Amazon Fire phone, Nokia 930 (no LTE), Nexus 6p, Axon 7, Xperia XZ, XZs, XZ1, and now an Essential PH-1.

What did the AT&T agents say when they wouldn't activate LTE?
When I received my XZ1c last week, data would not work at all - LTE or 3G.
After playing around with settings for an evening, I chatted with the AT&T service rep first thing the next day and he was happy to enable LTE using the Sony IMEI. I don't know if it depends on customer service agent, or if there is a policy difference, or what.
I purchased a Note 8 from T-Mobile in September. I was told by T-Mobile that if I didn't like the service, I could take my phone and go back to Verizon. Unfortunately, the coverage in my rural area is too spotty. I went to Verizon and they said my Note 8 is not compatible with their network. They said I can connect to the 4G network but I can't connect to the 2G and 3G networks where I can make calls and send texts. I was told I can flash the phone so it will work on Verizon. Is this true and if so, how do I do it?
Thank you so much in advance,
Mike
Hi guys,
I rooted the phone, installed audio and viper mod... but the only reason I even got that far was trying to root the phone to get additional bands added to the modem. Seems like I am not getting far lol.
The ulefone power 3s I got does not work in canada for bell... as it lacks 3g apparently and only has 2g and 4g? 4g data works, calling phone with 2g works. So data works for bell mobility and rogers, but voice and sms does not work with bell mobility... only with rogers/fido/koodo.
I am going to switch to rogers from bell due to better cost (45 a month plan with data) vs 80+ with bell... so ill get voice working but im worried then how much this phone will work when roaming in the states and what have you....
I seem to be only able to find how to edit bands with qualcom based phones but ours is a p23 or mtk 6763 processor phone.
Did you figure this out?
Just wondering if you were ever able to unlock the bands. I am having a similar issue
Fault of the smartphone made in mediatek：
The japan domestic carrier company where iPhone is set to use all of carrier bands in Japan merely hangs SIM lock and sells a terminal, but even which carrier is available if I cancel it.
However, there is no human being who wants to use this even if the phone which is how much which is the phone which is usable only in Japanese Tokyo where only a measure band of 3G and the LTE is usable because it is sold domestically without most of the carrier bands in Japan being available is bargain as for the smartphone made in mediatek
Even if the person buying it appears if baseband sets it freely and can add it, such an application does not exist.
Because I get the root right, in z3c of sony where band addition is possible freely by QPST and QXDM if it is a phone of snapdragon, there are still many users
The smartphone made in mediatek is a really useless (not smart) phone in Japan
Has anyone been able to confirm if this phone will have VoLTE with t mobile on bands 12 and/or bands 71? Also does it have WiFi Calling support on tmo? I'm beginning to think that Sony is going to force me to switch to Verizon soon with their last couple of certifications.
I am wondering the same. I have T-mobile and am considering upgrading to the Xperia 1, but if you can't get 4g lte data speeds, then it would be a no go.
I currently have the LG V30, and downloaded the LTE Discovery app. It says I mainly am connected through bands 2, 4, and once or twice I saw 12 pop up. And I currently have 4g lte speeds. In the specs for the Xperia 1, it does list it has those bands, so the 1 should be ok to upgrade to, no? Anyone else have the Xperia 1 and have T-Mobile? How are the data speeds?

I can confirm you that there is no wifi calling with xperia 1 on Verizon. I used xperia 1 on Verizon for 2 weeks and there just wasn't any option in the phone for wifi calling. My model was US unlocked J8170

most of the things should work
I did look on this specs first, after I got it seems like there is something additional. There is one spot I get a super connection but 90% of the time weak or no Service at all. I have tried many phones before but none of them even had such bad reception. And there supposed to be even the Tmobile 5G 71 Band. It looks to me someone sold a restricted fu.... Asia version without mentioning it
go to settings and all the way down you should see your model number. Considering that USA specific is not out yet you most likely have asian one which is XQ-CT72. EU one is CT54.
But those should work on t-mobile network, most of the bands are there. And those are low bands, so longer range.
It runs at limited feature support. Sony disables VoWIfi for US models and many other features including Bluetooth features such as Bluetooth meta data.
Sony blames T-Mobile for limited feature set. you will need to root your phone to hack up the build to enable VoWifi and other features.
This feud between Sony and T-Mobile has been going on for the past 10 years and Sony still playing ignorant to US market.
if you don't care about such limited feature set, Xperia 1 IV should still work on TMO
I just got my phone yesterday and realized the same thing happened to me, I didn't have service where I used to but I managed to get it working by: going to settings, then network and internet, then Sims, scroll down to access point names. And two options should pop up, I changed mine to T-mobile US LTE.. And restart, which worked for me.

Are you saying the the imported version of the Xperia 1 iv does support VoWifi or neither one will on any USA carrier

that is correct, the issue is more related to Sony software rather than just the region. the only way to get VoWifi is to root your phone and disable sony software limitations

yeah this guide should work, its for the Xperia 1 III, I would think it would work for the IV, I just switched to goggleFI to get Wifi calling with out having to do anything.
Getting VoLTE and VoWiFi on unlisted carriers by flashing mbn file
I live in Canada and I have a BC72 (Asian version). I am struggling to get VoLTE and VoWiFi working. I know that mbn file is the key to getting IMS support and sony seems to block some carrier mbn files (only mbn in sales areas are available). So...
forum.xda-developers.com
I have been using the XQ-CT72 here in michigan on GoogleFi, which is basically t-mobile, in my town where I live, I get 5G without doing anything to the phone, but with that said, I work 20 miles out in rural area and apparently from my research tmobile use band 71 for 5G in rural areas, I can get LTE+ but no 5g at work, my Pixel 6 pro can get 5g but its like 1 to 2 bars that`s it, but with my sony I get full bars of better signal on LTE+ with my Sony, since the Sony is missing the n71 band for 5G, but I`m fine with what I get, since at work I` m on wifi anyways, I`m happy with my purchase, I originally had the US model on pre-order and the release date was pushed back to Sept. 22-23, so I cancelled my pre-order and bought a new one on ebay for 1069.00 compared to sony wanted 1599.00 for US mode
EDIT: I ended up send it back to seller, the 5g icon was not really 5g, if you're in the USA I would wait and buy the USA version, which I pre-ordered from Sony website, expected ship date is 22-23
moving to GoogleFI is the best option to use this phone in the USA. it will utilize Tmobile USA and have all feature enables.
Can anyone comment on Verizon compatibility with this device?
If really like to save some money and not buy the bootloader locked na version (if locked is still a thing)
Thanks

Only way to know for sure it to just buy it and try it for your usecases. Just buy it somewhere with a good return policy. I bought mine on Ebay with a 30-day return policy and so far it works fine on AT&T. Just make sure you do the trick where you disable dual-sim. (Google the details, it's somewhere here on XDA or on Reddit).
I bought my USA variant phone a week ago, and everything on T-Mobile works with the exception of Wi-Fi calling. The only alternative we have is to stop using T-Mobile and switch over to Google fi which does support Wi-Fi calling. Other than that my phone is flying super smooth and with fast performance like I've never believed compared to my old LG v30 Plus. I'm definitely impressed with this phone.

I'm using mine (XQ-CT62) in the Verizon network. Reception is not the best in the area where I'm but it works with no problem
Is that a coverage thing most likely, or the device itself? Rural area?

From a technical point of view, the phone should work on all carriers in the USA without issues, (with the exception of the Sony/T-Mobile Wi-Fi Calling issue that forces those who want Wi-Fi calling to switch to Google Fi, Mint Mobile, and other MVNOs).
Whatever service is in the area should work. Verizon will provision your phone to work with it's network. CDMA based carriers are supported per Sony's phone settings, so I would just go for it.
