Hi, im looking for a phone which would work with both verizon and T-mobile. Why both? well im in an odd situation, where im halfway through my contract with verizon, but want to switch to T-mobile. But my phone right now barely even works at the moment, so i need a new one, which I can bring over with me when i switch to T-mobile
I need a phone which works on both carriers or else I will end up buying to phones at full price, and I wouldnt want to do that!. Any help wpuld be extremely appreciated, there has to be some kind of smartphone out there thats capable of this

A lot of phones these days are tri/quad-band. This means they operate on 3 or 4 frequencies ranges.
I'm not from the US so I'm not 100% sure but I believe Verizon is a CDMA based network while T-Mobile uses GSM (or WCDMA).
This would mean that most phones cannot be taken from one to the other. However many newer phones are released in carrier specific versions but don't have any hardware differences. Its often very hard to test/confirm this without having the specific device in your hand.
Google suggests that the iPhone 5, 5C & 5S from Verizon is unlocked and works on T-Mobiles 3G & 4G networks. So this could be an option.
As far as android handsets go, most of the phones I can find dont have a good overlap of frequencies for both networks.
Using the LG G2 as an example, the T-Mobile versions of most handsets use 850/1700/1900/2100 for 3G and LTE Bands 2, 4, 17. Verizon uses 850/900/1900/2100 for 3G and LTE Bands 4, 13. There is a little overlap there, 3G @ 850, 900 & 2100, but the LTE coverage is limited to Band 4 which could result in some negative experiences coverage wise on T-Mobile.
While I was working in Korea, I bought a Galaxy s3 SHV-E210 (Korean Model) cell phone. When I bought, I was told that I would be able to use it over here in the States. AT&T was able to put a sim card and activate it on their network, however I only get 3G. The Sales rep told me that the bands for 4G/LTE are different in Korea than stateside carriers, so I may, or may not pick up 4G/LTE. I've done some research and found that the band in the phone can be changed using certain codes. When I enter *#9090# it brings up a menu, I've tried changing some of the 4G/LTE, 3G options in that menu but I never get 4G. I know how to root and put custom firmware on devices, so if that is something I need to do then I am comfortable with that. Can this phone be changed to get a 4G/LTE signal? are there any more "codes" that I can enter in to get any other options that will help me? has anyone here ever change the band on their phone to work on 4g? Thank you for any and all help.
AT&T uses LTE band 1 for service.
since E210S only supports band 3 and 5, and 3 and 8 for E210K, there's no way to access AT&T LTE network with your device.
It is reported to support band 1 for newer devices like S5 and G3 and AT&T LTE devices might work in Korea since May 2014,
LTE won't be available with Korean S3 in US.

its working for me after covert the the os to international version
Hi,
There's a thread going on on the Vodafone UK forums about the Nexus 9 LTE not connecting to Vodafone UK on anything higher than 3G. I don't think this is very well known as the LTE version isn't as popular as the Wifi version, and then there are multiple mobile operators to choose from, so this might not affect many people.
Basically, a known working Vodafone 4G SIM in a known 4G coverage area will only establish 3G, never H, H+ or LTE/4G - this has been tested with multiple devices (I've got two here now) and multiple SIM's. The devices are unlocked, Vodafone don't require IMEI registration or anything like that. It should just be a case of putting the SIM's in. I've done all the checks I can think of (SIM's in another device - they get 4G, other operators SIM's in the device get 4G) etc.
Vodafone use LTE band 20 (and band 7 in a very few locations for LTE-A). Band 20 is known to work on the radios in the device because the same devices can connect to EE, who also use LTE band 20.
HTC are not interested as they say its a network problem, the device can register on EE and advised me to contact Vodafone.
Vodafone are saying its an unsupported device, I didn't buy it from them and don't really care, their first line support said the SIM is registering on their GSM network but never registers on the 4G network hence no coverage. After a conversation with second line support I was told that the device is trying to register on band 8 (900MHz) rather than band 20 (800MHz) which means that its a software/hardware problem - I'm a little bit dubious about this as how would they know unless it was negotiated by the SIM or something as their equipment uses 800MHz... ? I think he was basically lying to me to fob me off.
Google don't even have a way of contacting them about the device.
So as a consumer I'm stuck! Is there anyway I can debug the device myself? Can I see what bands are being used at different points in he SIM registering process with any software? Basically - any help or advice at all guys. It sucks to spend a load of cash on a device that half works, but what REALLY sucks is having no way to escalate a clear cut problem because there are so many companies involved!
Thanks in advance!
Dears,
I need your help. I have Gear S R750T running on R750TUVU1ANJ7. I have just rooted my Gear S following the exact instruction in this link: http://forum.xda-developers.com/gear-s/development/definitive-guide-to-rooting-gear-s-t2973455
Unfortunately, SIM Card still not working even after rooting. There is no coverage appear in the watch.
Do you have any solution or suggestion to overcome this problem.
Thanks,
A.AZIZ
I have the exact same issue.
USA phones (and GearS watches with phone functionality) use a different communication channel than those for Europe/Asia.
So, if you're trying to use a phone/watch designed for one set of frequencies (for example USA uses dual band 850/1900) on a network with a different set of frequencies (in Europe it's 900/1800) it will simply not work.
You should definitely research this kind of info BEFORE buying any GSM type device (phone, smartwatch, 3g/4g tablet, ...) or you'll end up with a "WIFI only" device
EDIT :
Here's a list of countries that use the same frequencies as USA :
https://en.wikipedia.org/wiki/List_of_United_States_wireless_communications_service_providers
Also, for Yemen the network uses the GSM 900 system, so an American phone won't work : http://www.gsmarena.com/network-bands.php3?sCountry=YEMEN
Thanks verzipo for your reply
Thanks verzipo for your reply
I don't think the problem is the band frequencies as most mobiles whatever be GSM or CDMA brought from USA are working properly here in Yemen. Only mobiles which are factory locked or restricted by a carrier need a back door solution either by rooting or some utility applications. I feel frustrated and cheated by buyer that I spent more money for the Gear S on un-used feature in my country.
Anyway, I will try my best to use the WIFI feature to its end limit to compensate
Thanks Man again.....
Hi,
has anyone experience with this Phone in the US ?

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.
