I have a vzw line. Popped in vzw sim. Then popped in my tmo sim. Data and calls work. Speed was faster on tmo sim though.

mine works well but i cant get video or any of the tmobile **** like that to work

I just picked up a Verizon S8+ (i had a T-Mobile one but just returned it) and i popped a T-Mobile SIM Card in it and i got a message saying "This is not a Verizon Wireless SIM Card" and it wouldn't let me use it. I thought it was supposed to be unlocked??

It is unlocked. After swapping Sims the only change you got to make is change preffered network mode from LTE/CDMA to LTE/GSM oh and go to APN and choose your new sim card apn. And thats it. Ive tried all carriers on my Verizon S8+ with no problems

What probably will not work on any carrier phone other than TMobile will be WiFi calling when using TM SIM.

Hey! I need to know if I buy a s8+ in Verizon, I will can use in Chile with my local carrier? I can read that you don't have problems changing the carrier in USA, will be the same if I use the phone with a Chilean Sim? Thanks!

I have a Verizon S8+ on AT&T unlimited service and it works perfectly. So you'll be good for Tmo as well. I have no clue about Sprint tho.

I have a Verizon S8+ on att and it works great. Does anyone know if I get HD Voice with this combination ?

Verizon unlocked S8 plus on T-Mobile working flawlessly for me

Verizon unlocked and works very well in France on the Orange network.

When I got my VZW S8+ I popped in my tmo sim first thing. It worked flawlessly out of the box. I didnt even have to add any APN settings as all of the tmo settings were built in. Awesome job sammy!

What about video call ect I'm having issues getting that **** to work is u pres *#77467# it says false on all the **** why won't the ims register that controls all that

I have an issue with s8+ using AT&T sim. The issue is that the phone shows a plus sign in front of my all incoming calls treating them as international calls. Does anyone know the solution?

The phones are completely unlocked, what you need to do is look up the VPN settings that T-mobile, or at&t use for their phones and set them accordingly. Though some functions might not work with non-Verizon carriers through changing these functions. (messages, video calling, etc..)

Thank you all. I bought the s8+ from Verizon out right because I wasnt sure if I was going to stick with them. And it looks like I am moving to t-Mobile this month, I was going to look into flashing the firmware, but I was worried since I used Samsung pay like crazy. So I am fine with just disabling the verizon apps and going from there.

Anyone know if the phone will still get updates if I swap in a T-Mobile SIM, or a Verizon-compatible one from Straight Talk while still on the VZW firmware?

It will if you use the VZW software update assistant. I've done 2 updates this way on my Verizon S8+ with my tmo sim in there. Works fine.

Sounds good. Do you know of the Verizon phone has all the bands of the T-Mobile version?

Fully work - no. Things like HD calling and wifi calling wont work without t-mobile software.

SIM unlocked T-Mobile Z2 Force - on Verizon?

There are a ton of entries on XDA about sim unlocking the T-Mobile and Sprint versions of the Z2 force, but none of them confirm once unlocked if they've used it on Verizon.
T-Mobile's page confirms their version utilizes bands 2,4 and 13 - all of which are Verizon's LTE bands.
Can anyone confirm?
I'm looking to buy this to replace a work phone on Verizon. My personal account is with T-Mobile, so would be very nice if I could just flip sims whenever I'd like. Appreciate in advance the responses!

(unlock T-Mobile bootloader, sim unlock, root and put a custom rom with safety net passes)
then type this on google and try.

Oh if this works I would be so happy to switch back to VZW. Anyone attempted it yet?

I'm interested in knowing if anyone tried this too

I’m too chicken to mess with anything not official from xda on my daily driver. I’m sucking it up and waiting out the period for the device unlock app to ‘officially’ sim unlock and try. When that day comes, I’ll post here.
I think it’s ignorant having to wait for a sim unlock for a phone you bought outright.

Eagerly awaiting news on this - why is there a waiting period on the sim unlock? How longs is that period? I'm about to head out to Tmobile store and buy me one too.

Verizon's LTE band 13 is exclusive to the Verizon model unfortunately. I wish it wasn't so you could use a bootloader unlocked Sprint or T-Mobile edition on Verizon. I did that with the Google Pixel - used the universal one on Verizon. I just got used to having an unrooted phone with the z2 Force. I switched to blokada after many years of always using ad away. I think most all ad blockers on unrooted phones are VPN based so it lags WiFi and mobile data a little but that's what you get to work with if you want the best moto phone running on Verizon.

Could you provide your source of information on that? T-Mobile's listing of the Z2 Force lists band 13 LTE capability, and multiple sources say that the Sprint variant has band 13 too. I am just about to pull the trigger on a Z2 Force variant that is bootloader unlockable, but whichever carrier version I get has to work with Straight Talk Verizon.

I'm seeing the sprint one listed as having band 13 now everywhere actually. My bad. I don't recall seeing that back when i got it and was shopping around. Let me know if the Sprint one works for you on vz because i miss having a a rooted phone.

The only different thing on the US phone's is the oem partition. Everything else hardware and software are very similar to the point I want to say identical. (Obviously, some slight changes in /system and stuff but that's with the territory of using OEM ROMs). I have flashed a T-Mobile flashall and it worked. I flashed back to Sprint shortly after. I did it for science.

So in short, will am unlocked T-mobile Moto Z2 work on the Verizon network with a sim swap? Or does it require a root or the bootloader thing that was mentioned, I haven't done either one as I am content with factory.

So, what's the verdict? Will unlocked T-Mobile Z2 force work with Verizon?

Most likely will not work. T-Mobile variant is GSM and most likely doesn't have the CDMA bands on it or programmed into it. Only thing you can try is flash Verizon firmware and see if it works. 99% chance T-mobile firmware will not work, Verizon firmware has about a 40% chance of working. If you don't have the device, I'd suggest not investing as no one has tried it.

I tried the Verizon flash all on my TMobile z2. Didn't work.lost baseband.
The flash all looked as if everything flashed properly...but when it finished and rebooted it still had tmo splash screen. So I don't know if it really did it.
If it's worth any thing my Verizon Sim in my tmo z2 gets great data...just no calls/messages

I have an unlocked Sprint variant that I flashed to Verizon and use with Straight talk Verizon. The only issue is that so far whenever an update comes in I have to back up all the things I want to save and flash the updated flashall, because the automatic updater just keeps on failing. I don't know if this matters, but I'm bootloader unlocked (had to for sim unlock) but without TWRP or root. It's possible that if I would try relocking the bootloader that the automatic update process would work. I briefly had a Mint sim in there (T-mobile) and everything seemed to work. I didn't really try things out with the Sprint rom, but as I remember everything worked, I just didn't like the icon style plus always having a notification saying something about a non Sprint sim card

Was it officially unlocked or was a modified file flashed to your phone? If you had a third party service unlock, then the hash check for that partition is incorrect and that's why updates fail.

I had a third party unlock it. Actually, it was the guy that people on this forum have talked about.

Will this work on Verizon? My tmo z2 was unlocked by TMobile not a third party

No it doesn't work... You can get data but that's it..

Hi- I am wondering about being able to buy a new-in-the-box z2 Force that was originally sold for Sprint, and being able to flash the T-mobile firmware to it for use with them. Is this possible? I have done this for Galaxy S8/S9 phones, but there is a deal right now where I can get this phone with 2 of the mods for dirt cheap, but it won't really matter if I can't do the conversion. Any advice?

Unlocked firmware (U1) on Verizon S9/S9+?

For those of you that have the Verizon S9/S9+ .. have you flashed the U1 unlocked firmware? Any bugs?
Do any of you still have the grandfathered unlimited data plan? Wondering if I can get the VZW S9, flash unlocked firmware, and have native hotspot work.

I have successfully flashed U1 and Tmobile Firmware on my g960 (verizon version)
So far, I have not noticed "bugs"
From my understanding U1 is what you get from Samsung Directly. With that said, you wouldnt have any incompatibilities as the barebone hardware is the same in the US variants.
One thing that I dont know though is software updates, if they are pulled OTA or if I have to flash every time.
Advanced Calling works as well as Wifi Calling and visual voicemail.
video calling doesnt work unless you flash a carrier firmware
If you have the grandfathered account with verizon, and you flash the U1 firmware. You can wirelessly hotspot or USB tether "natively"

Thank you for the information! Bummer about video calling, I use that more than visual voicemail.
Definitely sounds like this is the way to go.

Hi there,
I have a verizon phone and I am trying to use the hotspot with my unlimited old fashioned plan. I don't want to root. Unfortunately I brought the Verizon s9 not the Samsung S9 unlocked. Is there a way to bypass the company prompt for the feature and turn the hotspot on yet? I tried the one that works for sprint and it did not work for me with Shortcut Master Lite. Any advice would greatly be appreciated?

yeah you can flash your verizon s9 to the U1 firmware. this will remove that message, but not all things are guaranteed. also its not like youd be able to root your s9 as you got the US variant.
While I have a verizon hotspot plan, I tend to use USB tethering more than the Hotspot(wifi) option.
Checking on my dashboard online, shows that Im constantly within my Hotspot Plan.
I also noticed that on USB tethering, data doesn't count against my Wireless Hotspot plan.

Hi Eastsidebiz
Thank you for your reply. I apologize about not understanding all the lingo. When you say flash is that different than root? If you can flash and not loose your warranty or anything. My question is where do I go to have that done? Or is it something I can do myself? Also what will I loose as far as stock features if any? I appreciate any feedback and really truly thank you.

Flashing the firmware is different from rooting
Flashing the firmware is like installing a new OS on the computer.
Rooting is flashed preboot of the OS, and then executed when the OS is up.
Warranty / Knox by flashing an OEM firmware, this should not trip warranty/knox
rooting a US variant, if you can even do it, will trip your knox, thus tripping warranty.
If you have a US variant, come back to this thread 2 years from now, as i dont think developers are able to do so as of yet.
this thread is very informational if you need to flash your U version to U1.
Which s9 do you have again?

I thought I'd update this thread. I bought the VZW S9 and successfully flashed it to the U1 firmware to get rid of the verizon bloatware. Nice side effect is that the hotspot seems to work.

hey just a FYI.
If you flash another carrier firmware on that s9, you maybe stuck there.
personal experience: I can flash from Verizon to U1 and from U1 back to Verizon, (until verizon patches their firmware to lockdown)
on my other s9 (verizon, work phone) I flashed to U1 then flashed to Tmobile, now Im locked to tmobile, until another U1 and or Modded Odin

Thanks for that notice. As of right now I don't see any reason why I'd be inclined to flash anything other than the U1 firmware that I currently have.

Hi There,
So you are saying if I flash to U1 software I can use my hotspot. That is without being prompted by Verizon to add feature. What have you lost in the software from the U1 Flash compared to Verizon Software. If I do it and it voids the warranty so be it. I just want to see what I would lose before I do anything.

What does it mean to be locked to T-mobile? Does that mean you can flash another stock firmware?

Flashing this will rid of the bloatware from VZW and you can use the native mobile hotspot or PDANET
Locked to Tmobile can be a couple things, the Phone is actually locked to Tmobile's network (sim locked) ..then theres the Financial/Loss/Stolen/Fraud lock...
ALSO! have you updated your VZW S9's software from verizon in the last 3 months? If so, flashing a U1 may not work, I think the newest Update from VZW has v2 of the bootloader

What is your carrier?
I noticed that TMOBILE is the only one that allows all features to work when it comes to unbranded phones.
On my VZW s9, I flashed the U1 firmware. (using Tmobile) Then Wifi Calling was under the SAMSUNG DIALER option not in CONNECTIONS.
Then on my Unlocked S9, Wifi Calling was under the SAMSUNG DIALER settings (on tmobile), on Verizon SIM, this service is not available.
It looks like VZW/ATT both use their firmware to block outside access. Tmo on the other hand, allows you to fully use your Unbranded phone, but such terrible and outdated technology.
*for those who are getting 20Mbps on Tmobile and happy about that... why??!!?!?*

Unfortunately my phone seemed to have the latest firmware out of the box (February security update) so I might be out of luck then.
My carrier right now is Telcel Mexico (and we don't have fancy features like WiFi calling or VoLTE). I'm planning on switching to T-mobile soon.
What's that of the 20Mbps on Tmobile? Should I pick another carrier?

Wait Feb 2018 may still be V1 bootloader....
So what I noticed with Tmobile (im sure this doesnt apply to everyone) is after 1.2 to 2 years. Your phone line is no longer "new" and data speeds are dropped to least prioritization. Newer plans or line activation obviously gets higher prioritization. Mind you, im not a prepaid user. The only way to fully take advantage of TMOBILE is to switch your device or renew your plan every 2 years, which makes sense and average to some.
on the other hand, I have been having Verizon for the past 4 years, and used 3 different phones then (no line modifications, upgrade.. etc) and my prioritization has been constant. and averaging 70Mbps real time, about 7-9 MB/s (i download torrents on my phone) and its always constant (even if i go over 65GBs a month)... just my 2 cents...

Here's my take: I bought bought an S9 U1 direct from Samsung, did a Smart Switch backup of my damaged S7 to my pc, swapped the SIM and SD cards to the new phone, powered it up, did the Smart Switch restore and was good to go in under an hour, hot spot without prompt etc.
Based on this, if you can flash the U1 firmware you should get the results. The kicker to that is the bootloader version. My wife's s9 from Verizon took the August update and is now on build ... S3ARG9 - the 3 indicating v3 of the bootloader. The latest U! firmware available is S2ARF4 - bootloader v2 and you cannot downgrade the bootloader. BUT if you happen to be on the ARF4 or earlier build then go ahead and flash. Samsungs Voicemail app works with Verizon's VVM (basic), Messenge+ also worked, though I switched to Mood so that I can assign specific notification sounds to certain people.

Att to Verizon.
I bought a in Att s9 g960u phone and I want to use it on Verizon. I got a sim unlock code from a 3rd party so it is sim unlocked but I put in a Verizon sim and it doenlsnt connect to verizon. Is this because of the Att phone uses GSM and Verizon uses cdma? How do I get around this

Phone hardware should be the same. Possibly flash the U1 firmware. Or you may have to enter in carrier APN settings - I've never had to do anything like that but I have heard about it before.

Unlocked vs Tmobile/Flashing Carrier

I'm curious as to what doesn't work when you purchase an unlocked version vs Tmobile branded? Im told you may have issues with wifi calling/rcs/video calling/and visual voice mail....
2. How easy would it be once you get the unlocked version to flash the carrier software to make everything work and then flash back to original if needed to be for resale or warranty
The reason im asking is that samsung is giving a bigger refund on the unlocked version...

If you live in the US I think the unlocked version is just a SIM unlock. I think it is still the snapdragon version. Which means it will not be bootloader unlocked. I think you have to get the exynos version from an online retailer.

Note 9 was able to do this and I did it. I don't see a reason why you shouldn't be able o do it in Note 10+ once carrier firmware become available to be downloaded.

I pre-ordered the unlocked version myself and I have AT&T so it should be as easy as waiting for the carrier firmwares to become available on SamMobile and flashing with Odin. My interest is now with DeX supported with microsoft if Odin is even neccessary to flash firmwares anymore?

from what i can see on sprint i think they are using the qualcomm chip, i could be wrong, its labeled as SDM 855 Octa-Core SDR8150 and when searching that in google qualcomm documentation on the 855 pops up

Very curious about this myself. I preordered the unlocked version because that gave me more value for my trade in. I'm curious if I get the unlocked version and flash TMobile carrier software. Will I then get tmobile updates ota?

It's been the same for years now, hardware wise phones are the same, you'll need princey odin to flash unlocked/carrier firmwares. I buy unlocked and flash the carrier unlocked firmware. No bloat but it has the carrier specific radio. I prefer the native caller Id, no bloat, and the RTT over the carrier bloat and video calling. Google duo is better anyway

Are you TMO or ATT? I have accounts with both.
I know WiFi Calling, which is what I really need as far as carrier goes, is usually more difficult with ATT.
If you are TMO can you get WFC to work without flashing carrier?
How long do you usually have to wait for the carrier firmware to come out?

Wifi calling has no issues on unlocked firmware with tmo. At&t I'm not sure but if you flash the att csc and and cp files, I do believe that's all it takes. I believe you need to flash the at&T AP file.

My Note 9 is unlocked. Using on T-MOBILE with no issues with WiFi calling. I am not able to use the stock visual voicemail though which I would prefer. With T-MOBILE I'm forced to use their visual voicemail which really sucks. Does anyone else know if they're is a way to use the stock visual voicemail on T-Mobile?

When I inserted my SIM it appeared to automatically install the T-Mo firmware, but that's the problem.; it forces me to use the T-Mo VM (which absolutely sucks) and not able to use the Samsung VM which is pretty nice. I had previously used the Note 9 on Verizon with my work SIM and I was able to use the stock VM. When I switched to T-Mo it forced me to use the T-Mo VM. I can't see a way to get back to the stock VM unless I'm missing something...

I go into the phone app call or SIM settings and find the call forwarding settings:
Then I do they conditional forwarding to my Google Voice number (I then, after setting up Google Voice, turn on Do Not Disturb for Google Voice, so I don't get there phone ringing twice)
Then GV serves as my VM

If you live in the US I think the unlocked version is just a SIM unlock. I think it is still the snapdragon version. Which means it will not be bootloader unlocked. I think you have to get the exynos version from an online retailer.

^^ What he said. Do not make the mistakes I, and many others made in the past - do NOT buy a US version from T-Mo, or from Samsung USA website, unlocked or otherwise. All USA versions are snapdragon based, and will have permanently locked bootloader - no rom flashing of any kind, no custom recoveries or improved radios. What you need is SM-N975F/DS Exynos version (unless you use CDMA carrier like Verizon or Sprint). It will have the same bands supported as Snapdragon one, with the exception of band 71, which you dont really need. T-Mo's B12 serves the same function as B71 (extended range LTE), and T-Mo made the tech available only in limited number of cities anyway. In all likelihood, by the time they roll it out in your city - you're gonna be thinking about buying Note 12 or 13.
Don't worry about software features like voice calling or any other - with all the custom roms and development available for Exynos version you'll be able to find yourself a rom that has any features you like and then some.

This is great advice ..... IF ..... you are looking to root and/ or do custom ROMs. But having done every release S9+/Note9/S10+ with Exynos it's NOT always that easy to get the CSC stuff right and working (and the development is often done by people who could care less about NA CSC because they don't live there).
Root / Unlocked bootloader = the Exynos device, like you said.
So what appears to be the answer (for the thread, assuming no root) after looking at all the answers in this and a couple of other threads is that the Unlocked US Samsung device is the same (or can, in worst case scenario, by Odin flashing carrier firmware, be made to do) device functionally as the carrier devices --- calling features, etc.
For me, the difference was going to be $300 bigger discount.

That's only true if you want to unlock the bootloader and root. The OP was merely asking about flashing carrier firmware on the US Unlocked version, which does not require root or an unlocked bootloader.

the bigger trade in value was a deciding factor as well for me...Well we weill see how it goes on the 23rd

I want to be able to root and flash TWRP on my Note 10+, but when i did this on my Note 8 i bought the N950N which was the korean exynos version and CRC support for t-mobile sucked ass, i want to make sure
A) what model do i buy for
- Rooting and stuff
- and best t-mobile network compatibility without going through all the dumb stuff

Same here. When Samsung stopped hobbling the OS, and added more features I didn't need root anymore. The extra $300 was my deciding factor. I have the unlocked Note 9. The only thing I have noticed aside from slower updates is that the camera sound can't be turned off independent of the global phone sound. Everything else works fine and I haven't noticed anything useful missing.

I was actually giving advice to all folk, considering purchasing, not just the OP....Also, just curious - how do you Samsung's locked bootloader on the unlocked Note (I hope you know 'unlocked' means SIM unlocked only) will accept firmware, signed by T-Mobile? It's not a given Samsung original bootloader, untainted by carrier branded modifications, accepts carrier signed ROMs. You may need to be using T-Mobile version of the bootloader, for it to accept T-Mobile signed images.

Unlocked S20+ on Verizon

Anybody have a S10 series on Verizon answer a couple questions for me?
I would like to confirm if or not bot Mobile Hotspot and MMS message work properly.
and any other quirks and besides the benefits of no belote ware, I'm planning on getting a S20+ but the Verizon version is $300 more than unlocked and I don't need or want Wi-Fi calling.
Thanks in advance

Curious if there is really an advantage to unlocked vs carrier in this case beyond ease of resale?

I've had both an Unlocked S10+ and a Verizon S10 (running Unlocked Firmware) on Verizon. Mobile Hotspot/MMS works on both, along with all other Advanced Features (including Wi-Fi calling/etc).

Thanks that's what I wanted to hear.

Had a similar problem on my S8 with att, flashed the att stock firmware through Odin and volte, and wifi calling worked. I have since changed over to the stock unlocked firmware to send in my phone for trade in and it doesn't work anymore. I order the unlocked 20+ as well do I'm hoping just flashing whatever carrier branded firmware for it works again.
