please clarify using unlocked phones on tmobile - General Questions and Answers

So with the refarm..can you clarify some things for me. An att phone will or won't get 4g hspa+42 on tmobile? If and when Tmobile gets LTE will an existing att 4glte phone will or won't work on tmobile future lte network?
If an att phone will get 4ghspa+42 and future tmobile 4glte
it would seem to make more sense to get an SIII unlocked att phone since it would future proof things in that it unlike a current tmobile version would eventually get 4glte?

No
I believe there are currently no att phones that get 4g on tmobile. I do think 1 or 2 tmobile phones that will work with att. Lte depend on the band of lte if it will work or not but most likely no

but if they do the refarm woudn't att bands work on tmobile?

[Q] Any Samsung phones 4G LTE instead of Wimax?

I am looking for a new phone but don;t want to get stuck with a WiMax 4G phone again when I could be using the local LTE 4G that is around me.
I would be interested in peoples comments on a new phone.
Thanks
I'm confused the only carrier I know of that has wimax is Sprint and they don't have LTE yet, so what I'm guessing you are asking is if there is any Samsung LTE phones for Verizon or ATT am I correct?
The only phones I can think of that have LTE on those carriers that are Samsung are the Galaxy nexus,note,skyrocket,Droid charge, and the stratosphere.
Your best bet is the galaxy nexus...good all around (LTE only with Verizon)

[Q] How to get 4g on my Sidekick 4g with at&?

So I bought a sidekick 4g thinking I could use my at&t sim card for it and got it unlocked but have one problem. I can only get 2g at the most on my network and asked the service provider who provided me with the unlock code for a solution to this. They told me something about T-Mobile running a different network than at&t and how at&t was updating there network so that I could get 4g on my phone and how it was going to be ready before the end of this year... Is it possible to get 4g yet or any other way around this?

Nope, that person lied to you as well.
AT&T and T-Mobile have different HSPA (4G technically) bands. I think AT&T uses the 850mhz HSPA Band, while T-Mobile uses a different one. Since thats the case, your SIM Card is looking for a band that the phones modem dosent have. Thus, knocks you back to EDGE. Forever.

AT&T LTE Phones on T-Mobile's LTE network

So T-Mobile seems to be ramping up their LTE coverage and my area seems to be one of the LTE markets.
I was wondering, would now be a good time to buy an AT&T Android LTE phone (like the Note 2 or GS3)?
I'm not entirely clear if the LTE on those AT&T phones will work with the current/future T-Mobile LTE network.
Right now I'm currently using an iPhone 4 on T-Mobile. I get spotty 3G coverage since I'm in one of the 1900MHz refarmed areas. Would using an AWS LTE compatible AT&T phone let me get T-Mobile LTE service?
Is T-Mobile eventually going to get rid of their 3G service on the 1700MHz frequency so they can use it for LTE and then put their 3G service on the 1900MHz frequency?
I can't afford a brand new phone, but when it comes to used phones it always seems that AT&T ones are cheaper to buy than T-Mobile equivalent.

It has been my understanding that AT&T and T-Mobile smartphones are network cross-compatible because they use the same bands for HSPDA and LTE. So as long as you have the following, you should be good to go.
First and most important: ***Phone Unlocked***
The correct sim for the carrier.
The correct APN settings for the carrier. (If this isn't auto-populated after the new sim is in the phone, you can search here on XDA for them.)
Lastly, apply any patches/fixes/tweaks for the particular device where needed. (if needed)
As for this network cross-compatibility changing in the future, odds are that it probably will not happen any time soon as this would be very costly for the carrier to change so soon after launching the LTE service. Post-LTE, maybe, but that is at least another 10 years away if I had to guess. :fingers-crossed:

How to Convert Verizon M8 to AT&T

Hello,
I have a Verizon M8 that i'm using with AT&T. Is there a way to convert my Verizon M8 to AT&T so that I can get LTE? Or can I at least flash the AT&T radio? I noticed this video shows a method for converting Verizon M8 to Tmobile https://www.youtube.com/watch?v=6GhybCyd4Pg He is getting Tmobile LTE with Verizon M8 no problem.
If someone can point me in the right direction that would be great!
This phone doesn't have the bands for At&t LTE. Best you would get is HSPA+.

Yes I know it doesn't have compatible bands for AT&T LTE. It doesn't have compatible bands for Tmobile LTE either, but someone demonstrated how to convert it so now he's using the Verizon M8 and is able to get Tmobile LTE without a problem. So there seems to be a way.
I figured it out. For anyone else out there that has a Verizon M8 and are using it on AT&T, you can convert your phone to the AT&T variant. I'm getting LTE but not constantly, it switches between LTE and HSDPA but it's staying mostly on LTE. Yay!

So how did you get it to work ? On the verizon forum all there is, is for converting to tmobile lte and nothing on converting to get at&t lte. Also what lte bands of at&t are you running on ?

Hey there. I posted how I did it somewhere in the AT&T forum. I'm not sure where the post is though as it's been a few months and I don't have the M8 anymore. I sold it and bought a One Plus One, then sold that and bought a Note 4, so that was a couple of phones ago.

Unlock 4G lte bands verizon M8?

Hi,
I'm using a verizon M8 on a non-verizon network. The Verizon version should support 4G LTE on band 3 and 14 (the hardware should even support 3,4,7,13). My provider supports 4G LTE on band 3 and 7, yet i don't receive 4G.
I'm guessing Verizon locks 4G to their network. Is there any way to unlock my phone so i can use 4G LTE with my provider? (T-mobile NL)
I am willing to do anything. Already reflashed my phone with verizon ROM but that doesn't help obviously because it's not a stock rom..
Thanks!
There is a working solution for the Android:
http://forum.xda-developers.com/verizon-htc-one-m8/general/lte-band-7-2600mhz-finally-guide-t2992523
I think, there IS a way to adopt it to the Windows Phone.
htc m8 for windows verizon
Any news how to activate lte band?
looking for this too. In my country there are 3/20 bends and verizon edition has that band but I cant use 4g
