T-mobile to Verizon. - Verizon Samsung Galaxy S8 Questions & Answers

Will the t-mobile version work on verizon if I change the firmware? Or even better. Will it work if I switch it to the U version just like my T-mobile s7 edge did?

Hey there, yeah it works great

[Q] Should an unlocked ATT S4 be as good as Tmobile S4 service?

I talked my wife into switching to Tmobile and gave her my S4 from ATT. Her service is not so good and I'm tired of hearing about it. I've tried different modems from ATT but no real improvement. Anyone have any experience on the subject? Aside from wifi calling, would a phone from Tmobile have the same service?

No, they use different bands. You can use a T-Mobile phone on AT&T just fine but an AT&T phone on T-Mobile will not get you the correct speed connections due to the limited bands AT&T uses. That is why I decided to go with the T-Mobile variant rather then any of the others.
I see. Its a tough one. Att is getting so locked down but tmobiles service is sketchy where I am. I would hate to pay for a new phone when the S4 is running great still. Damn. Thanks for the input.

You could sell the phone and purchase a T-Mobile variant of the same phone to run on AT&T or upgrade to a newer T-Mobile phone. The T-Mobile bands work great on AT&T network, just not the other way around. That's what I have done. I have tried the AT&T and the Verizon phones and they both work good on AT&T but if you want all around compatible phone, then T-Mobile phones are the way to go. Just get the unlock code and throw in any sim you want and set up the APN.

[Q] Can you use the S6 EDGE AT&T version on T-Mobile?

Can you use the S6 EDGE AT&T version on T-Mobile? Or would it be better to get one from T-Mobile and use that on AT&T and T-Mobile?
You can but only 3g I believe
T-Mobile probably since they have root and all that jive. But why would you want to have an ATT phone on T-Mobile?
Because I use ATT as well. I think the ATT variant didn't have 700mhz.
LTE worked.

That's really good to know. I saw a video on YouTube I can't recall which one though that shows the At&t phone prompting to do a T-Mobile software upgrade. Of course this is after the phone is unlocked and a T-Mobile Sim card is inserted. Is that true or is it a load of manure. Thanks in advance!

Unlocked sprint note 4 sm-910p on tmobile

Wondering if there are any tmobile roms that work on a unlocked sprint version. I'm using a sprint rom now and it works ok. Just want to be the most compatible with tmobile as possible. I am a noob to using unlocked phones. I was with sprint for 10 + years and just switch to tmobile last week. Thanks in advance
Update- i flashed the the tmobile maximum ovrdrive n5 rom and its working great! Came from a sprint hybrid note 5 rom. Wiped and did a clean install and everything works great. Still no lte but my 4g has gotten better speeds. My new question is im still on my sprint ok1 modem should i try a tmobile modem or stay with it the way i have it?
I don't believe you can use a sprint phone on tmobile. Different network. And as for the rom. I don't think there are. I could be corrected but sprint phones are only good on sprints network and that's it.

Modern sprint phone support T-Mobile and ATT's HSPA network. Heck I used my unlocked Sprint S4 on ATT for about 5 months without any issues. Only thing was that I didn't get LTE.

sm-n960f/ds on at&t

ive been looking everywhere and im not 100% on this BUT will this model work on at&t? lte and everything? might trtade my unlocked note 9 for one
It will work on at&t but you might miss out on some network features like carrier aggregation which gives you faster download speeds. But other than that it would work fine on at&t.

Works fine. You're not going to have wifi calling, and there's a band or two we're don't have on the phone they ATT uses.
I have been using a 960f/ds on AT&T for a week or two now.

It will work but you will miss lots of AT&T Features and a few bands are missing, Also no wifi calling thats one of the features there's more features that wont work can't remember now, So if you care about your AT&T Features then it's really not worth getting theses International Phones, Also the Network is Slower Than the one Snapdragon AT&T Has on there phone, Cause of the Bands Missing.
I on att on 960F/DS. Works fine. Speed is the same where I am compared to my att note 8 but that could be because if where I am. If I'm missing a couple of options it's worth it for the flexibility. No issues.

Unlocked sprint LG V40 good for Verizon/GSM carriers?

Hi, I was wondering if an unlocked Sprint LG V40 is good for any other US carriers? any band restriction? Many Thanks.
As far as I know I have the full V40 ThinQ LM-V405UA network unlocked and factory unlocked version and it works well with ATT and T-Mobile as well with sprint am not sure if it will work with Verizon because as you know Verizon and Sprint do NOT like to support each other's phones even though they are in most cases IDENTICAL in every way.
I did do a check on verizon BYOD site and it says Mine is NOT compatible with there system as I had guess it would say that.

Hi Zxhwk, do you know if T-Mobile Wifi Calling is working and do you get full 4G LTE speed on T-Mobile? I don't know if there are some bands missing for T-Mobile 4G LTE.

I'd really like to know this as well.
LM-V405UA is way cheaper used than a LM-V450TAB!
I'm using unlocked sprint with Verizon network, works fine except advanced calling when you use your data together with the call. Spring uses different technology for that which does not work on Verizon. Also voice mail notification does not work. Otherwise no issues
Can the Verizon image be flashed to the sprint hardware (which appears to be identical) to get the Verizon advanced calling features?

Yes you can flash the Verizon KDZ
Can I replace the motherboard from a Verizon or AT&T LG V40 with a T-Mobile one? I ask because the T-Mobile LM-V405TA can't be rooted and it would be cheaper to buy a motherboard than a whole nother phone.
