So I am leaving Montana for south Korea soon and was pretty excited to learn that my Rezound is global capable. The only thing is I am unsure if it will work on a Korean SIM card, or how to do so. I am s-off running the first leaked ics ruu. Do I need to ruu to the global firmware? Or will any gsm capable roms work without a firmware update? Also, if there's any one out there who has been to south Korea and could give me some tips on providers to choose from it would be appreciated.

You need to install the official Global RUU, leaks can be problematic because they prevent you from getting OTAs on stock rom and may not be the latest, most stable software.
I think there have been like 2 official firmware upgrades and several leaks between what you are running and global.
You do need a GSM enabled ROM, and one that is based on the global firmware. Simplicity or Newts One XXX 5.08 may be good options for you if u want to stick with a Sense ROM.
You may still need to call Verizon re: international calling, although I wouldn't mention I was rooted.

Thanks for helping. I was a little unclear in my original post however; I actually am running Newts One XXX 5.1.0 currently (awesome by the way). What I am wondering though is this; will the fact that I am not on the global firmware mean that I will need to RUU update in order to get service with a South Korean provider. I do not plan on trying to remain with Verizon as I will be in South Korea for more than a year.

You will have to ruu to global firmware to obtain global radios to work with the global Rom

rezound in rok
I'm also heading to the rok and hoping to use my rezound. I'm on stock ics ota. I'm going to see what I get on a stock rom before I do any unofficial releases, but I expect to drop SMS capabilities or maybe data like you see in the states with a T-Mobile sim in. I arrive in Korea on the 31st so I'll update sometime late next week and let you know. I've been to Korea before and I believe we will have to go with SK Telecom as our carrier because it is the only GSM network. The other networks are cdma to the best of my knowledge. Hopefully my next update will be from my phone on a Korean network!
Rezound in South Korea update
In Korea now. I just flashed my phone from a stock OTA ICS, unrooted, s-on over to the Global RUU found on Androidpolice.
I have tried to buy just a sim card from several stores, SK, KT Olleh etc, and the stores all say that I have to go to the headquarters stores located in Seoul, Yongsan Train Station on the top floor. Apparently this is the ONLY way to get a sim for a global phone, other than having a korean national get one for you and give it to you. This weekend I will be going to the headquarters stores and getting a sim, Other problems you may run into are related to being a foreigner in Korea. They will sometimes not want to sell you a phone on a contract because you as a foreigner could disappear at any time without paying the bill. So, they will try to get you to buy prepaid. I don't want to deal with prepaid anything, but that may be a viable option to get a SIM card easily. Just buy a reallllly cheap prepaid phone that has a sim in it, pull the sim and throw it in your global enabled device. Unless you speak Korean, navigating to the headquarters and getting what you want may prove a bit difficult. Fortunately, I do speak Korean, so I will let you know how it goes.
I will update again once I actually have a Sim in my phone!
Thanks for the valuable information so far. I will be arriving there at the end of November and am looking forward to hearing more about how It's going for you there.

got a sim, no data!
Finally got a sim from KT Olleh today. The girl at the counter didn't believe me that the phone would work, but I got her to do it anyway. By the way, don't try to set up service for a phone anywhere in Korea on a weekend. They cannot activate a new phone unless its a weekday. So anyway, got it all setup and the girl sits there and plays with my phone for a while without saying anything to me. Then she tells me that the calling and texting is fine but the phone won't get a data signal. I asked her to set the APN, and she said she did. I checked it out and she had put in the KT APN as alwayson.ktfwing.com Looks right to me, and she seemed to know what she was doing for the most part. Then she started to go on about how Korea runs on CDMA for the most part and not GSM yadda yadda.
So, I have a Rezound, working for incoming and outgoing calls and text on KT Olleh, but no data signal at all. I might repost a similar message in another forum topic to see if any gurus have any advice on how to get it working. Also going to do some more research. I'm new to this but there is tons of information out there. I will post again once I have resolution or give up and buy a new phone!
PS Phones in korea can be REALLY expensive. Dropped 850 on my wifes LG phablet (optimus VU2)!!! Equivalent to the instinct in the states I think?
didn't flash twice
So, I am a phone noob, and did a lot of reading last night. Saw that most people flash rezounds twice anytime putting on new firmware etc. I think I will try that tonight and see if I pick up the data signal.
The ruu's generally need to be flashed twice. However I did not need to do so going to the global, the ruu automatically took care of everything.

website for kt olleh
Some helpful information that KT Olleh has to say about using a non-korean phone in Korea.
http://expatblog.kt.com/71
The rezound may not have the radio frequency that network uses. That would be the main problem as to why you aren't picking up data.

I am currently in Seoul and have rented an Evergreen Mobile Sim Card that works on KT Olleh's network. I am curious as to whether you were ever able to get your Rezound to work with their Data network, and if so, how? Mine works with Olleh Wifi for free but will not even recognize the 3G, despite my having changed the APN settings, and even going to the Evergreen Mobile office in Yeoksa-dong today (they said they couldn't get it to work after an hour of fiddling with it themselves).
Suggestions? Do I have to root?
Oh, and the link in your above post has expired. Could you summarize what KT said?
Thanks!

Sorry if this issue has already been posted, I am new to this website.
So I just purchased a Lumia 920 from Rogers and unlocked it to use on Telus.
Unfortunately, I had no idea that these phones had so many problems when trying to put them onto a new carrier.
Im getting problems such as:
Tethering Issues
LTE Connectivity Issues
Map downloading Issues
Unable to activate my nokia account through the phone
Now, I have managed to find solutions to most of these problems, but they do not always work. I have solved these issues with some of the most common solutions like:
Using the Access Point setting
setting isp.telus.com as the APN
manually setting all MMS/APN settings
What I want to know is:
Are any of the available ROMs on navifirm plus "Unaltered"?
And has anyone been successful at solving these common problems with any of the ROMs?
Also, on a side note, when I try to install Nokia Care Suite 5.0 I get Error 1723, I have not found any solution to this as of yet (could it be that I am running windows 8?).
*************************************FOUND SOULUTION*****************************************************************************
Basically i decided to try flashing my Lumia over to an RM-821 international developer version (1232.5951.1249.1002).
There is another dev version available on navifirm (1232.2110.1244.3002), didn't try this one.
Had to follow the steps in this thread: http://forum.xda-developers.com/showthread.php?t=2112674
After a painstakingly long process, and worrying whether i would brick my phone going from RM-820 to RM-821 it seems to now be working.
- The APN settings are now configured automatically by the phone (dont need access point app anymore)
- MMS can now be received without problems
- Ugly Rogers boot logo is gone
- phone now displays H+ instead of 4G
- Tethering works flawlessly
Some issues remaining:
- cannot add my nokia account to my phone (had this issue before, was very hit and miss sometimes you could, sometimes you couldnt)
- unable to recieve LTE anymore, the cellular options show a maximum speed of 4G, ill keep you guys updated on this tomorrow as i had this issue before and just had to go downtown and then it magically started working.
Ill keep everyone posted
UPDATE****************************
LTE works fine, I was also able to add my Nokia account (only with high LTE reception).
however, my MMS issues are only half fixed. Can't receive any MMS from wind mobile users (Rogers, bell, Telus work fine.)
You are not going to get LTE service on that the 920 as long as you are using Telus. The LTE Frequencies for the Lumia are 850/1900. Telus uses 800/1800. The frequencies are hardware controlled and cannot be altered. Not even a new or different ROM will solve this issue as it is hardware related.

I actually did manage to get LTE running on telus. It just doesnt seem to like working when im in doors or away from the heart of down town toronto. But it IS working.
That still leaves my other issues though. I kind of gave up on the phone. Been trying to sell it ever since which is a shame because its a nice phone.
Too bad nobody is interested in a barely touched unlocked lumia for more than 350 bucks.
I did very recently unlock my ATT Lumia 920 and I'm using Telus. I'm considering flashing a European Dev ROM, but I'm wondering if I will be able to get LTE working. Can you please more specifically mention the steps you used to get LTE to work?

That's not correct. According to wikipedia, Rogers uses bands 4 (1700 MHz) and 7 (2600 MHz) for LTE, Telus supports the only LTE band 4 (1700 MHz). Thus technically everything should just work out of the box.
Hi all, sim unlocked s-off sprint m9 used to work well on android 6 with official rom. But until the phone was upgraded to Android 7. Data connection stopped working for one operator (NOS in Portugal). However Vodafone works well.
Tried different roms and apn settings, same at all. Data connection does not work on NOS operator.
Does anyone have similar issue and of course any advices?
Thank you all.

Why sim unlock a Sprint variant and not an AT&T or T-Mobile which already support GSM?
did you find a solution?
i have exact same issue.
bought one m9 from ebay with sprint (651) firmware on.
lte was working fine in israel (1800 2100).
after nougat im only getting 3g.
it makes sense that i cant use those bands (1 and 3 i think) on a sprint device.. but it did work with marshmallow
Same problem in the USA
I have (nearly) the same problem in the United States with a Sprint CDMA version of the One M9. The main difference is that my data speed is even worse than 3G, around 10-20 Kbps. Occasionally, I get faster speeds, but I haven't been able to figure out if it is location-specific (but always away from home and work) or due to some other characteristic.
The phone came brand new in a retail box from an eBay seller. It worked as expected for 1.7 years. The OTA update which installed Android 7 (aka Nougat) in early 2017 resulted in the very slow data speeds. WiFi is unaffected, but data is so slow that I cannot reliably send or receive MMS; Google Maps says that I do not even have a data connection for traffic info.
EcoMobile (my MVNO provider; I still have a sprint email address, so I know who is actually providing service) could only suggest resetting my phone; did this twice with no change in operation (but several of the programs which automatically re-installed themselves operated differently, including GMail no longer providing auto-complete for addresses).
After literally 2 hours in chat with htc, they told me that my MEID indicates my phone was "made in Taiwan". I took this to mean that: 1) the person I was chatting with had poor English skills (because aren't they all made in Taiwan?), and 2) my phone is gray market (meaning it was not imported into the country via official channels, even though the manual was in the American version of English).
I came to XDA looking for an answer, too. I was mildly surprised to see that this topic was at the top of the list for the One M9.
The best solution for my situation would be the proper ROM for my phone, but I don't know how to figure that out from the MEID. htc USA says they cannot help me with this.
I could even go back to Android 6, but I do rather like the new features in Nougat.
Alternatively, I could root the phone and install a 3rd party ROM, but I still need to know how to choose the proper one for my phone.
I hope this info finds its way to a helpful expert.
Regards,
Jeff
OK, so I was with T-Mobile forever, and I bought this phone from them at launch. I decided to switch over to MetroPCS by T-Mobile because it's cheaper, so I paid off my phone then unlocked it (Even though I didn't need too, the Metro SIM worked in it before I unlocked it).
It worked fine for two weeks, and I had WiFi calling and everything, and then the RJ5 (I believe?) update came out, and when my phone booted up it said new sim detected, and WiFi calling was gone. My APN settings were set to MetroPCS', so I set it back to the T-Mobile one since it's essentially the same network, but the WiFi calling option is *completely* gone; it's not there, trust me. I call MetroPCS support and they said they can't enable it for devices that weren't bought from them, and I tried to argue like sure you can, send it up to a higher level support team, but I could hardly understand her and gave up.
I went into a MetroPCS store and they had a spare T-Mobile SIM, popped it in, boom WiFi calling was back.
Come OneUI Pie update one, I opt in and update, and voila, WiFi calling is back!
I just downloaded the second update last night, and now it's gone again. This **** is driving me crazy, if anyone can help me figure out a way to fix this I will love you forever.
Wow, that was a gripping good yarn! I think there's a good chance that if you switch to the unlocked G965U1 firmware, it might work. I have an unlocked Verizon S9+ running on TMO, and once I flashed it to U1, wifi calling and volte worked automatically. I'm not positive how it will be with Metro but it is worth looking into. When you flash the collect unlocked firmware, when the phone boots up it will detect your sim and then reboot and configure all the settings for you.
P.S. I don't suppose there's Metro firmware out there?
I don't think there's Metro firmware, because my updates still come from T-Mobile. T-Mobile owns Metro. So what you're saying is flash the firmware via Odin and my phone would be like truly unlocked and I would get updates from Samsung rather than T-Mobile? I don't want to go through all this if it isn't a a certain fix, but sadly there's no way to tell that.

For some carriers, the Wifi calling requires the phone to have carrier firmware. Verizon is one. I bought my 9+ from Samsung unlocked, and it didn't have wifi calling on Verizon until I reflashed the phone (using Patched ODIN) to a Verizon firmware and Wifi calling works... as does the Verizon bloat, but most of that can be disabled with Package Disabler pro or similar app.

I don't think MetroPCS has it's own firmware for the s9+. Plus, they're owned by T-Mobile now. The plan I'm on is called MetroPCS by T-Mobile lol. This is driving me nuts.

Out of curiosity I read around a little bit and it seems to be really hit and miss, which definitely seems to match up with your experience. I did find this post on Reddit from someone saying they got Wi-Fi calling to work with a Metro Sim: https://www.reddit.com/r/tmobile/co...g_volte_not_working_with_metropcs_sim/cymnvhf
Have you come across that, tried any of that?

I have not, thanks for the link, I shall try that. Funnily enough, there was a hotfix pushed out last night and WiFi calling not working was on that list. I now have the WiFi calling icon in the notification bar, and it shows like it's on, but it doesn't actually work, and me pressing it does nothing. The setting itself still isn't in connections or anywhere in the settings. This is so dumb, lol.
Just got my Xperia 1 III (XQ-BC72) couple days ago, flashed SEA firmware with no problems so far. Except too bad it doesn't support Volte in Canada, which used to be fine on my previous Xperia 1 J9110 with SEA firmware as well.
I was wandering is that possible to flash it with US firmware to unlock that, plus features like more 5G bands support?
Anything helpful would be appreciated.

Hi, any updates on this? I have an XQ-BC72 coming, and if I can get USA firmware on it I am hoping it will work for me.
Question for you: how did you flash the SEA firmware? Official Sony tools / firmware upgrade?

I flashed US firmware yesterday but it appears that it still wont work with Verizon even though all the 4G bands are there. I could care less about 5G where I live. I have CMDA less feature activated too but still no go. Worked fine on the HK version of Xperia 5 II so I though I would be OK on this one as well.
@i7killpii you are unlikely to get VoLTE to work (aside from maybe on T-Mobile). Its possible that a Canadian provider may also allow it but I doubt it. You also wont get access to more bands just by switching firmware. Whatever bands came with the phone is all you have access too.
@charlatan01 you can follow the directions here: https://forum.xda-developers.com/t/guide-flashing-xq-at51-firmware-on-xq-at52-device.4147027/
These are for the Xperia 1 II but its the same process for the 1 III as well. If you use Verizon and somehow figure out to make it work, let me know. Please note, flashing firmware will erase everything. Also I am not responsible for any bricking or issues you may get into. It worked for me on the first try.
I flashed my XQ-BC72 using XQ-BC62 rom before. I cannot afford 5G plan so I didn't try. About VoLTE, I am using Fido and the carrier services are not available (including VoWiFi, VoLTE, showing 4G instead of LTE, etc.). Also I got a lot of problems such as LTE connection disconnection about every 30 seconds. So I flashed it back to TW rom. Still all carrier services are not available but at least the LTE is functioning.
I've searched about the carrier services issues. It seems it's because the carrier isn't cooperating with Google so no carrier configuration is available (I'm not sure because fido has android phones on their website).

Thanks for the follow-up. I managed to cancel my order for the Asia version and am going to snag the NA version when I can.
try only flashing /OEM partition with the OEM files of the firmware from your area.
Usually that brings VoLTE functionality and stuff

I called Verizon and got them to add the IMEI to my phone line along with CMDA-less feature. It actually worked. I can make phone calls and send/receive texts so it appears its possible to get Verizon to work on Asian model. However, VoLTE is a different story. I dont think I will get that work.
