I live in the US, and I am currently subscribed to Verizon Wireless Prepaid Service. I was thinking of buying the S9+ International Exynos Unlocked Version. I know that it doesn't have CDMA support.
But here's my question:
I have a S8+ which was bought from T-Mobile, and it didn't work on Verizon Wireless because it wasn't registered. So I flashed the firmware and it worked. I later got a B.Y.O.D simcard. This would mean that the GSM(Sim Chip) is the provider of the Verizon Wireless service.
So is it possible that the S9+ will work on Verizon Wireless as did for my S8+?

So I'm switching from verizon to T-Mobile after this month and I was wondering what would be the best way to flash the T-Mobile firmware and get rid of the verizon firmware?
Firmware is not the problem. TMO & ATT have GSM radios, Verizon & Sprint are CDMA. Your Verizon S5 *will not* connect to the t-mobile network no matter what firmware you are running. T-mobile probably still has a very generous trade-in program.
Actually the Verizon S5 should work as it contains an LTE radio, meaning GSM functionality is present. Furthermore, the Verizon model comes unlocked as per FCC regulations. You will need to set the proper APNs to get connectivity on the Verizon S5, however.
Short answer: The S5 works on TMO.
I just made the same switch two months ago. I had two S5s and an S4. My dad is still using his VZW S4 on TMO and I used both of my S5s. However, the coverage seemed to be less than optimal and I wanted the WiFi calling options so I bought two used TMO S5s and my dad is getting a Kyocera Hydro. Even with the cellspot extender my dad's S4 won't make a call at his house.
I guess I got it wrong. DOH! Thanks for setting me straight. So what about going the other way, would a TMO S5 work on the Verizon network?
Pros/Cons?
Pro: No AT&T preinstalled bloat
I'm using an Essential PH-1 unlocked with AT&T. No problems.
Used a Mate 9 unlocked on ATT with no problem. Most US unlocked phones should work without any problems on ATT
VoLTE or HD calling as AT&T calls it might work on an unlocked phone if they will provision your line for the service. They did it for my Pixel 2 and it worked after I got a new sim. I don't think wifi calling will work on any phone except an AT&T device. I would make good use of this service so I'm opting for the AT&T version. If I find wifi calling works on an unlocked model I may switch but I don't think it will. We do some vacationing at a place with wifi but no cell service. My wife's AT&T iphone has it and it's pretty cool.
If the unlocked version is snapdragon then it will work just fine and lock to USA AT&T. With the S8 phones they were unlocked until you put a SIM in it and then it locks to that carrier. I'm curious is the unlocked version the exynos or the Snapdragon?

The snapdragon is the only processor sold in the usa whether you are unlocked or carrier specific.
Having issues with SM-G965F on AT&T LTE
I just activated my SM-G965F and I'm only getting 3G and 3.5G (H+). No LTE. If I change the mobile networks settings to nxtgenphone, it connects to LTE, then drops and I get no data. I can only use the 'phone' version. My AT&T account has a grayed out device for my account. Checking compatibility with the IMEI checker for AT&T says it cannot determine if it is compatible. the 2nd SIM slot IMEI number is considered invalid!
Heading to the AT&T store at the mall later... not expecting much help.
I have the Note 8 and it was a PITA to get it full working on AT&T. Only thing that interest me was the Volte for talking on the phone and data at the same time, never got it working 100%. Had AT&T provision with new chip still not working good, so I sold the unlocked and got an AT&T model and had it unlocked and all is working well.

It was not the APN settings, entirely. It was that myAT&T would not recognize my IMEI number as a 9+. So, working with a store clerk at the local mall, she suggested to punch in a fake(last number altered) IMEI number using the in-store SM-G965U models. Since this has nothing to do with actually logging in or SIM verification, it worked. The SIM does its job and my account has an S9 (not a plus) on it, so when I changed to the 'nxtgenphone' APN settings, it is 'allowed' to log in (that's my best guess, anyway).
There is no other reason why the SM-G965F would NOT work on AT&T LTE since it has 3 of the 4 LTE bands (band30 is not included, but is only used in new, dense environments to alleviate network congestion -- my understanding).

So if I buy and ship an unlocked Galaxy S9 from Samsung website, it will have Snapdragon and not Exynos? I'm in a US territory.
I'm getting a good deal off their website with accessories and whatnot buying unlocked but I prefer Exynos
I'd rather not post and make a new thread. If someone else can confirm, I'd be much obliged
Yep it does. Just make sure it's on Snapdragon.
USA snapdragon.
Any frequency issues? Can they be fixed?
Any T-Mobile features not useable?
As far as I know (saw on other threads) T-Mobile supports all versions. Or better said, T-Mobile won't block any features if you use another phone on their network.

Hi can you tell me how you unlocked att s9 plus, i'm not able to unlock with att or third party unlock site, thanks in advance.
Mine is bought outright.
Then requested unlock code on at&t site.
An independent dealer told me her att phone wouldn't do hotspot when on tmobile.
Maybe that varies per phone model and/or android version.
Would have to try to be sure.
Hi,
Have an unlocked ATT phone on Tmobile, wifi calling doesn't work.
That's why I'm staying on att...plus asking around, tmobile still needs better coverage here.
Well, I put the AT & T firmware put on my Galaxy 965u1 but since I am on ATT prepay Wi-Fi calling does not work and it looks like they do not offer volte on ATT prepaid, can anyone confirm this?
Hi, I'm new here.
I own Universal Unlocked Samsung S10 Model # SM-G973U1 purchased directly from Samsung. I originally activated it on the Boost Mobile network and Ive decided to switch to AT&T prepaid service. I find out that the SM-G973U1 apparently wont utilize the AT&T Wifi Calling (Per: AT&T Forum). I was informed I'd need the SM-G973U.
I'm also not sure if I'm even getting the 4g connection (My phone shows LTE, LTE+, H, H+ and no connection).
I believe I have bad cell reception in my house.
If I were to install the SM-G973U firmware onto my SM-G973U1, would this solve my problem?
Will my phone still be an Universal unlocked phone?
If I choose to switch back to the SM-G973U1 firmware should I be OK?
Would I need to do the same if I were to switch to T-Mobile?
Would I be better off switching to T-Mobile?
Any other thoughts about this topic I should be aware of?
Thank you for your time.
