[Q] Using the verizon variant internationally

Hi,
Just bought today the verizon variant of the galaxy s6, and I need help with a couple of questions:
I'm moving to Europe in the near future, would I still be able to use the phone?
From who do I get software updates? Will I get updates from verizon even if I'm abroad?
Would it be able to flash international firmware on this phone in the future? Are the models fundamentally different from each other or are they just handicapped by firmware?
Thanks in advance

Yes it works internationally, I'm using it on GSM right now and plan to use it in Egypt over the summer. You will get updates but I think verizon needs a verizon sim to check for updates but when one releases you can always check through a computer if you need to. As far as I know verizon one is the bay because it supports CDMA radios and GSM radios and comes pre unlocked while other versions like tmobile only support gsm. That's the only hardware difference, the rest is all software.
Also be careful with your phone! Nor sure where in Europe yuppie going but some classes visited Spain recently and lots of them we're pickpocketed and had something stopen.

So just to clarify, I can just purchase an EE nano sim card from amazon, take my s6 to london, pop it in, and it should work? I don't have to call Verizon before hand to get it network unlocked?

Correct. You may have to set up apns for data though. But text and voice should work out the box.

What can I do to use the GSM network, 3G !!!!
I live in china

3G only for China Unicom. Add the APN of Unicom and then H+ will work.

920V is different from the international version. It supports very few LTE bands and i'm not sure it supports as many 2g/3g bands as the internation one. you may have voice but you won't have LTE.

Hi,
Didn't u have the same issue with texting?
I bought my s6 from verizon on a trip in the USA, but I live in UK and using 3 network. The only issue is the texting. I spent lot of time to figure out what is the real problem, and it seems like it is sort of prefix problem. If I receive message from someone with new number with +4407 (obviously all of them start) and I reply, message is not going to be sent and I always get a message: " Your text to speech message to 0114407..... has been rejected by recipient phone." I never use text speech btw, and it definitely prefix problem because if I send to 07... only they receive it. I changed all my contacts to 07... but still after that I couldn't reply to messages for a long time just only with the Handcent next sms app. But If I receive a new message from a new number I'll get with +447.. and I need to save it and change the number to 07.. otherwise it will never work. I found some people had the same issue in the past, but there was no final solutions: http://forum.xda-developers.com/showthread.php?t=2106370
http://thedroidguy.com/2015/07/solutions-for-samsung-galaxy-s4-sms-mms-problems-part-2-110209
I am just wondering how is this gonna work abroad if I even can't use in the UK. I rooted and put clear rom, but still same.

How do I add a new APN? I found Settings -> Mobile networks -> Access Point Names but the "Add" button is greyed out

I am seeing it greyed out as well. I was planning on getting UK 3 sim cards for our trip next year.

Unlocked on T-Mobile

Hi!
Hey any functionality lost by using the unlocked version on T-Mobile ?
Thanks

When speaking to Samsung about this, they told me all T-Mobile bands are supported including 5G on the unlocked versions. What you may lose is video calling (who cares) and possibly wifi calling. But in the past I've seen threads were talking to higher-level techs at T-Mobile can enable those features.

I noticed Samsung checkout page didn't ask if you need a SIM for the unlocked phone. In the past it would give you an option. So curious if you will need to go to the store for a SIM.

Thanks . Video calling is big with me . Rats

My Note 9 was unlocked from Samsung but video calling and Wi-Fi calling work fine. Not sure about this phone though.

Won't you just be able to flash the T-Mobile firmware via Odin if you get the unlocked? Then you get the best of both worlds. This is what I did with my Note10+. Got the Unlocked from Samsung then used Odin to get the official T-mobile firmware.

Same here

i had an unlocked note 10 + on tmo and had no issues with video calls or wifi calling. i got from the samsung site that the note 20 has an esim which i would guess is why you dont see any wording for a conventional sim...

I currently use an unlocked note 10+ on tmo that isn't flashed. The only limitation is that I cannot do tmo-to-tmo video calling. It may simply be a setting on my end but I never looked into it as there are so many options. Everything else works fine and I seem to get every update at the same time.

To fix that issue you can flash TMobile rom onto the unlocked version.

Thanks. I haven't flashed a rom before but there's lots of info available. If I don't upgrade to the Note 20 then I will flash the TMobile rom onto the Note 10+. If I do upgrade I will eventually flash the Note 20.

TMO user with S20 Ultra here. Don't use video calling so I could not say. Wifi calling works.
Third party VVM apps do NOT work and TMO's downloadable visual voice mail app is garbage IMHO.
When I put my VZW sim in the same phone the Samsung VVM app works beautifully.
Unlocked S20 Ultra 512GB here.
"5G" works on TMO where there is coverage however the speed tests show LTE as connection type. Interestingly enough some of the speed tests actually show 5G. Not sure what's going on with that. Have reached over 200Mbps down on TMO "5G" a few times. Most of the time it's the same speed as LTE. Don't care, it works, hot spot works nice too.
If you were to (properly) flash TMO firmware (in theory) it SHOULD make your phone just like a TMO bought phone including the cheesy jingle when booting up. Never tried it, I like the slim as possible approach. Plus the ability to drop in a VZW sim and it just works IS a MUST for me.

tmobile visual voicemail has always worked for me on my samsung purchased unlocked 10+, so i guess our expectations are different.

Can't wait to see if I run into any issues with my unlocked on Sprint/Tmo

Only if you use TMO's downloaded app which is utter $4!+ IMHO.
I hate it so much I just dial in to listen the old fashioned way. I screen calls anyhow so the ONLY time it rings I know who is calling so not really a big deal. If callers don't have the secret PIN they get hung up on! F robos!

What about roaming on T Mobile partner network? Will I get a network on my UNLOCKED Galaxy Note 20 Ultra if I am roaming on US Cellular or any TMobile partner Network?
Will my Unlocked Galaxy Note 20 Ultra support all 5G bands from TMobile? (Low, Mid and High ) Layer Cake so to say.
What about SA 5G (Stand Alone 5G) that TMobile just launched. Will the Unlocked Galaxy Note 20 Ultra support it?

Sprint frequencies
I'm mostly concerned about the Sprint frequencies T-Mobile is picking up.

Unlocked Pre-Order from Samsung w ATT SIM - will I be able to use WiFi calling /VoLTE

Current Note8 user on ATT (phone locked to carrier). I pre-ordered a Note20 Ultra from Samsung direct, unlocked version. Have been off XDA really for a couple years and not rooting/modding much lately but have read that ATT will not allow unlocked phones on their network to use WiFi Calling and/or VoLTE. If true, are there workaround options for me (assuming I stick w ATT as the carrier I mean) to get these to work, or should I cancel the unlocked model and order the ATT version? Was hoping to root eventually and remove bloatware / play w custom ROMs again on the Ultra etc etc. - that is why I ordered an unlocked version.
Thanks gents for the guidance here! Best forum around for us phone geeks

If it will be like Note 9 or 10 plus just have to flash the U version csc with odin and it will give you wifi calling advanced..messaging..volte

Much thanks - I will do this then when it arrives.

Did not work for me on the unlocked note 10+. Worked right away on the tmobile.
Att was actually fun to have. Nothing that att expected worked on the unlocked device. For example I had unlimited hotspot, despite it was not included in my att plan.

That's bizarre. I am rethinking this unlocked route. I must have wifi calling since signal at the house is terrible in my area. I don't need the drama of uncertainty if this will work or not. Might as well cancel the unlocked one and just upgrade via att. Oy. Wtf is with att these days? They lost my directv account last year and now their wireless policies are looking like a royal pita.

I don't think you have to worry .... ATT seems to consistently allow Samsung unlocked devices to have carrier functions
You just have to flash the U CSC as mentioned above. Worked for me on Note 10 and is currently working on a s20 ultra device

Whats going on buddy. You jumping on the Ultra?

I strongly recommend switching your order to the ATT model. I got my note 10+ unlocked based off the suggestions found here saying that flashing the att firmware would give me all the features, and I've been through a year of headaches.
For a little wile i was able to enjoy wifi calling, voicemail and VOLTE, but after my first software update the features were lost. i was able to get them back briefly by putting my sim back in an old Att phone and keeping it for a day or two, but that trick never lasted past a week. I've tried re-flashing the software, switching back to unlocked and then back to ATT, basically anything i could think of and it never worked.
calling ATT didn't help either, as the reps gave me a canned line about not supporting outside phones. the whole reason I'm updating to the 20 ultra is to just get my phone fully functional with an ATT model

Thanks darth. Yeah, I switched to the att version. Hate the hidden tracking bloatware etc that comes with it but must have a very workable phone for daily work calls and wifi calling is a must. No drama is my motto these days. Thank you for reporting your experience.

I had the same situation with my unlocked Pixel 4 XL, keep calling ATT until I got the right person to modify my sim to allow WiFi Calling to work, that's my plan when I get my unlocked 20 Ultra.

I'm not a gent, but I doI have the Note 20 Ultra in for review and am using it with an AT&T SIM. VoLTE works, no option for WiFi calling.

What worries me is the 5G. Will unlocked work for ATT 5G?

It does on my unlocked Galaxy S20+ 5G. The Note 20 Ultra is a ways to release and their system doesn't yet correctly identify the IMEI, so I can't say for sure what will happen after release day.

Hi Lisa,
Your reviews are the best, so thank you first of all. Can you check if it has any eSIM capabilities? Supposedly S20 was going to get an update to allow eSIM use in US but that never happened...

Thanks . I'm not seeing anything under connection settings on our US unlocked Note 20 Ultra (there's no IMEI listed or cellular network option listed under connection settings when no nano SIM is installed. EsimClient is running on the phone, which makes me think the hardware must be there. EsimClient is not running on my GS 20+ unlocked.

Great, thank you for checking and comparing with S20+ !
eSIMClient running gives me hope that we will get eSIM support in an update...Still perplexed how or why Samsung has gone out of the way to disable eSIM on US variants when Apple, Google support it.

Ha! Thanks Lisa (love your tech vids!!) - I switched to the ATT version. Supposed to be here 8/21. I can't take a chance with wifi calling being borked, or that just that I may need to Odin-flash updates or CSC packs periodically to keep up with the monthly patches (ie force an unlocked unit to keep working on ATT's network if my previous firmware gets overwritten etc. I mean). I guess as I got older I went from a tech pioneer and adopter to just an end user LOL.... I just need it to work. Maybe I can do that package remove thingy and chop the bloatware periodically... we shall see once the community gets these units and starts their dev magic for us.
I guess I will need to make an appt at the local ATT store in a week to get on a new 5G plan from my current 4G one to take advantage of the coming speeds.

You're welcome- glad you enjoy our vids! With AT&T, you can simply change your plan online, no need to visit a store. The mid and high tier unlimited plans include 5G.

Question galaxy s21+unlocked(sd888) lte CA not config 0 0

I bought unlocked galaxy s21+ on samsung.com . I got the phone and I was so happy and i check everything like screen/benchmark test ... and everything was perfect. I currently live in Korea, and i brought this phone with me since there was no defect at all. I open the my cellular with KT which uses 8(900mhz) and 3(1800mhz) lte bands and the main band is 3
The problem starts here, when i was in U.S, lte+ which is enhanced lte, was working perfect through at&t, but in Korea it wont show lte+ and i did a little research and found out that my Carrier aggregation- CA- is not open? working? whatever its not working. found some ways to use it which was installing a korean s21+ firmware but ofc its not gonna fix the problem cuz U.S is sd888 and Korea is exy2100. SO i found a another way that is using a *#27663368378# but enter that number it says "undefined additional service. Contact customer centre"
damn please help me using LTE+. in living with a speed between 5~30mbps

let me know, how that works out. I have the same phone but in europe. It says lte on my phone but the speed is halved to what i get on other devices.

Question U1 VS Carrier Firmware

I have a TMO S22U and basically I immediately flashed to U1. I'm just curious are there any advantages I'm missing out on being on U1 opposed to T-Mobile U? I know there probably aren't many but I'm just curious.

Some say U1 us better. I'm At&t so probably someone on Tmo will chime in. But for me, U1 offered nothing over U. I mean yes no At&t bloat but I can disable what I don't want on U to get the desired affect.

My biggest thing was the T-Mobile splash screen, it sounds SO DUMB but flashing to U1 made it literally 100% Samsung for me I'm just wondering what could have been lol

The only thing I heard, but I am not certain about is that you lose the TMO visual email capability. Otherwise I have not heard anything else. I am on TMO and I kept mine on U. As butchieboy said, I just disable what I do not want. In all reality, there is not much from TMO that is loaded on the system side. More of the bloat is from Samsung and Google.

Thanks for the speedy replies guys much appreciated

One thing I noticed when I did the same thing, was I could not get 5G Ultra Capacity to work. Not certain I was doing anything wrong, just wouldn't work for me.

I think I read somewhere that you do get it, but there is no icon for it in the U1 image. It will show 4G LTE. Check your download speeds.

I did, 2 days apart in the same spot, the icon showed 5G as did the speed test connection type, but the speeds were much slower than 5G UC, almost 400 Mbps difference. Switched the firmware, back to the insane, almost WiFi type speeds.

Did you check the mobile networks setting to make sure 5G is available and selected?

Yes, that was my first thought. It never quite worked the way I should have.

preinstalled crap apps on tmo firmware

The main benefit for me on the unlocked firmware is the built in called id and spam blocking. For att you have to pay extra and tmobile has it on its best plan. But still think it works better than tmobiles implementation. And since i change carriers often i like to always have caller id and spam blocking no matter which one i use.

I downloaded the S980U1UEU1 firmware which on the latest update ends with AVCK. Used Frija to download it

Carrier firmwares usually get updated a week before the u1 series does.

Would've just been a considence. U1 firmware does connect to 5G UC just look at the service menu and it'll confirm if your connected to N41 or not.
But I moved back from u1 to tmv U firmware due to having weird call /sms issues where it would just stop working and only fix was a reboot. Hasn't happened since switching back to U firmware.

Here's an interesting question..
I was on TMO and I bought a S22U from TMO (unlocked it with them afterwards) and of course it was on 5GUC and everything (I used ESIM). I got another sim (Mint Mobile) and when used as primary it would show 5G+
After a while, and just out of spite of the hideous 4G LTE TMO icon I Flashed the U1 firmware.. I'm no longer using TMO as I ported my number to Mint and it has been good.. Would it make sense to return to TMO U firmware or should I stay in U1 as Im no longer using the TMO sim?

Probably fine on U1. You're no longer connecting to anything advantageous besides updates being slightly faster with U.

I'm with T-Mobile, but purchased mine directly from Samsung.. I have the S22 Ultra U1. Since my last phone purchased from T-Mobile A52 5G. biggest change, No daily spam calls or text.. What a difference that makes.. With T-Mobile, their so called Spam blocker was notihng more than a spam attractor. Plus no more of the hidious bloat and splash screen..

I have the unlocked and I dirty flash switch between U and U1 depending on which newest ROM is out. There's absolutely no difference save for the annoying TMOB splash screen and that it says UC ... But from my extensive testing the speeds are the same whether it says 5G on the U1 or 5GUC on the U.
