[Samsung Galaxy S9+ Guides, News, & Discussion] Scott:
I decided to move from VZW to T-Mo! Woooot!

First I will share my experience with the setup and porting of my new accounts then talk about using a VZW Phone on a T-Mo line. Yeah, I know there are couple of these threads already but they are somewhat old and unmonitored.

The transition went smooth but seemed to take almost 1.5 hours in the T-Mo store! I thought that was kinda excessive! I think the employee that was helping us was new. She didn't know much, couldn't explain anything, and kept going to her manager with every simple question I asked. Its all good, new employees have to learn! So I was fine with that aspect of the switch. It was a Sunday afternoon with nothing else going on.

They moved me from a 24GB Plan on VZW to the T-Mo One Military plan. I then added the $10.00 advanced data package on our phones. Its nice not worrying about overages and NOT paying an arm and leg for the data plan!

So my VZW bill went from about $350 to $150.00 on T-Mo. In all fairness I do have device payments on VZW, but moved those phones to save money. Will pay them off on the final bill. Still pretty happy with this! The device payments accounted for $80.00 of the VZW Bill. So I am still saving about $120.00 a month.

So now onto the service aspect.... Over all T-Mo, in FARGO ND, cant compete with Verizon! Not at all. Oh well, not too worried, I get decent coverage and "fair" data speeds.

At home, T-Mo gets about 10 megs down and 2 megs up. This was about the same speed Verizon had before they upgraded whatever tower was near my house. So, ok, at home, data sucks. No biggie, I have decent home internet package and to be quite frank, I never use my phone when I am home. I have so many gadgets with bigger screens to surf with.

At Work, Both Verizon and T-Mo get the same, 5 to 10 down and 1 to 5 up. Oh well. I can say that T-Mo is more reliable in this specific building for data when you are near a window, which I am. However, when you go into the building, where there are no Windows, T-Mo drops its data pretty low. We are talking about EDGE data. Verizon speeds would drop but not as drastic as the T-Mo. All in all I would say at work everything is equal.

Have not been around town much but when driving to work today I was using speedtest.net along the way. In general, Verizon beets T-Mo all the way from home to work.

So, now that I am a T-Mo customer with a Verizon phone I realized that there was going to be a minor learning curve. I cant get Advanced Calling features such as WiFi Calling, HD Calling, and Simultaneous Talk and Text! I knew something like what would happen because of difference in carrier implementation of those services. No biggie there. I understand that I would only need to flash the USERDATA partition to transform my VZW to a T-Mo s9+. Can anyone confirm that?

Also, I heard that the latest T-Mo update is hosed and not being pushed to the phone. I am currently on Verizon build ARE6 Dated Mid May 2018. I am not sure of the boot loader versions but I am thinking I should be able to go back one build on the T-Mo build and flash it. Hopefully. Anyone know about this?

Right now, I am at work, and I was wondering, was anyone able to turn on the advanced calling on Verizon Firmware without flashing USERDSATA? Also, those of you that made this switch with this phone, did you flash the T-Mo USERDATA? I was actually thinking about flashing the International Snap Dragon or the US Unbranded Snapdragon ROM on this phone instead of T-Mo. Did anyone do that? What sort of drawbacks did you have?
