I'm a T-Mobile Prepaid customer using a simple $19 phone but am planning to purchase a no-contract smart phone, say Samsung Galaxy S 2 or HTC Amaze 4G.
If I buy one of these for T-Mobile Prepaid, am I locked in there, or the phone is useful even if I might move onto another carrier such as Verizon or ATT, or to another Plan within T-Mobile later?

No you are not locked in if you buy a phone off contract. You will not be able to move to verizon or sprint with the phone though, because they use CDMA and not GSM like the rest of the world.
you can outright buy the phone, but check to see if they have a pre-paid plan/data plan for that phone, it will not be unlocked so you cannot move. You can request t-mobile to unlock it though, but you will not get the same 4g speeds
Please use the Q&A Forum for questions Thanks

Thank you. Does that mean I can use the Samsung Galaxy S2 No-Contract Model I buy from/for T-Mobil Prepaid now for other carriers of GSM? May I understand from your reply message(s) that T-Mobile is a GSM format carrier(and so is AT&T?) as opposed to Verizon and Sprint being a CDMA guys? If so, I can use the phone as long as my next carrier is a GSM guy? Does this make sense?

Thank you. I will do some homework in order to understand what "locked", "unlock" and " . . . will not get the same 4g speeds" mean.
Even unlocked the phone may not support the 3G or "4"G data speed between TMobile and AT&T. The AT&T Galaxy S II will not run on TMobile 3G data, only Edge (2G) data, because they run on different frequencies, same thing with the TMobile Galaxy S II does not support AT&T frequencies. If you buy the phone off contract from TMobile, they should unlock it for you, but there is no guarantee it will work (fully) anywhere else.
If you buy a phone off of craigslist even though you are buying it off contract you cannot guarantee it can be unlocked freely. For example if you buy an AT&T phone used from someone, AT&T will not unlock it for you for free until it's a certain number of months old (based on when the first person bought it from AT&T). You would have to pay a third party for an unlock code (if there is no help here on xda to unlock it).
It's best to just buy a phone for the carrier you plan on using. That ensures its going to work, and that it will work at full speed. If you really think you are going to switch to AT&T buy one of their branded phones, or Verizon etc. Verizon and Sprint both use CDMA, but they are very resistant to allowing another carriers phone on their network. Plus their 4G networks are different types (Verizon uses LTE, Sprint WiMax) so they wouldn't work fully regardless.
Thank you, quarlow.
My budget is around $600 max. So I'm inclined to purchase an HTC Amaze 4Z or Samsung Galaxy S2 for use for T-Mobile Prepaid at Target or at T-Mobile. T-Mobile Net Shop is selling Galaxy S2 Re-Furbished at a discount price. Hear Galaxy S2 have high rate of initial failures and therefore maybe better to buy a re-furbished one that has failed once and was repaired by qualified repairman. Below is how I come to think of buying a smart phone now. I've been happy with a simple prepaid phone buying 100 minutes at a time, which lasts more than a year for me. I also use a Sony Clie, a PDA running Palm Desk Top, which has gone obsolete long time ago. With a smart phone such as Galaxy or Amaze 4Z, I can leave not only the PDA but also a digital camera home. I do not need to access my PDA data over internet. I will import necessary data from my PC to my new smart phone either via cable or via WIFI before going out. That's why I want to remain "Prepaid Customer" not a customer with monthly fees. (Besides, I am not so much interested in leaving my data at ISP's servers.)
Thank you.
I haven't heard of high failure on the Galaxy S II's for TMo. But I have seen several studies showing refurbished devices have lower failure rates because they can have problem components replaced, and have to pass full qa testing twice.
If you are going to put all your data on your phone via USB on the computer, or wifi, then data compatibility won't matter. That changes the whole issue of taking it to another carrier. Any att or TMo phone that is unlocked will make and receive phone calls, text messages and mms messages just fine on the other network. You will only notice the difference when web browsing, or downloading files. If you aren't going to do that, then it wont make a difference.
Knowing that and your budget I would say get a international version of the phone. Get the Galaxy S II (i9100), or the Galaxy Note, or the Galaxy Nexus. All of those phones are top tier, and international versions will receive updates quicker. The Nexus being the Google device will be the first ICS device to get the next version of android, so its the most future proof. The GSM version of any of those phones will likely come unlocked.
The i9100 has a 4.3" screen, and 1.2Ghz dual core Exynos chip. The TMo version has a 4.5" screen (same resolution) with 1.5Ghz dual core qualcomm chip. The bigger screens did have issues with splotches and vertical lines far more than the 4.3" screen. With them being the same resolution the smaller screen is crisper. The Exynos chip is made by Samsung and widely regarded as the better chip, even at a slower speed. It also comes with a more powerful gpu than the qualcomm chip. So, the graphics are better, and games run better. The att version (i777) is almost exactly the same as the i9100, except it has the U.S. norm of 4 buttons, vs the international 3 buttons. The dev support on xda for the i9100 is unmatched by any other phone, its an amazing device with a huge support and user base.
The Galaxy Note is a 5.3" half phone half tablet with a stylus, and 1.4Ghz dual core Exynos chip. Its screen is a whopping 1280x800 resolution. But, for some that's too big.
The Galaxy Nexus has a 4.65" screen with 720p resolution (this screen is pentile which means it doesn't have as many sub pixels as it could. Its hard to explain, Google pentile vs rgb and there should be plenty of explinations. But, most reviews say at that resolution you need a microscope to tell). But the real strength with that device is that its the pure Google device. Its running Android the way its meant to be ran, unbloated and unrestricted. That is the Rolls Royce of Android phones for the next year. The Nexus S is last years Google device, and will be the first gingerbread device with an official ICS upgrade, if it isn't already upgraded. Its like a Mercedes at this point, its got the pure android experience, but its running last years tech: 4" screen, 1Ghz single core hummingbird chip.
I'm sure that is way more information than you ever wanted to know, but I hope it helps.

Actually the T-mobile SGSII supports AT&T 3g.

Att 3G runs on 850 and 1900, with preference on 1900 generally. The TMo looks to have 850, but not 1900. So like the vibrant the support will be spotty at best. It may work in some places, but not everywhere.

To quarlow and lowandbehold -
Very informative! Thank you very much.
I will stay with the plan to go for a Galaxy S2(i1900) or an HTC Amaze 4Z for TMO Prepaid. If there be good prepaid phone service(s) available from other carrier(s), I'd definitely want to learn about.
morning guys
I've seen a few threads about buying in the US and using the N5 in different countries and the fact that although you can use it for 3G/GSM, being able to use 4G LTE is a no go due to the bands that are utilised.
Does/Would anyone know if this is changeable due to the radio being used or would it be a hardware matter as to me it would seem abit odd to produce 2 different phones using the same form factor where a piece of software enabling the bands would be more cost efficient. I appreciate that the software etc is probably being looked at by Dev's now but was wondering if anyone with previous knowledge of this would know.
Only reason I ask is as I'm in the US at the moment (the 32Gb works out considerably cheaper than in the UK) and the area I live in (in the UK) hasn't got 4G (and probably won't have for a while), whether or not to purchase one and then wait for a radio change, but if thats not possible I'll have to go with the expensive UK version
thanks for you help
There are two Nexus 5 models, the D820 (for the U.S) & D821 (for the rest of the world. According to this article by Android Central, it seems that there is a physical difference between the radios installed in each model. So I don't think you would have the option of flashing a radio from a D821 on to a D820 and suddenly have access to UK/European LTE bands. I'm no expert though so maybe others could confirm/deny this.
I too would like to know the same thing (hoping to take advantage of relatives in the US )
However reading around a bit I think it's a hardware limitation. They use the same software on the phones, but they enable the different LTE bands built into the hardware.
Pretty sure no amount of flashing radios will enable the different LTE bands...I'd love to be wrong though.
Shame, even after sales tax the saving would have been worth it. Might have to bite the bullet and buy UK price £££££££££
Hi - several months ago I read a lot about choosing between Exynos (intnl through Best Buy) and Snapdragon/AT&T.
It seemed there were a few tradeoffs to consider.
First and foremost people said the Exynos performance and battery life were better, but then once the Exynos phones received a software update around May they started exhibiting the battery drain issue that seemed to be plaguing Snapdragon phones. So much so that numerous people were recommending flashing back to a previous update version to avoid the battery drain bug. Reading through the forums I havent been able to figure out whether these problems have been sorted out and corrected on either phone?
I also recall that the international version did not have ability to use Samsung Pay in the US? I cant understand based on the threads I have read whether this is now in fact possible?
I Have also read varying things on the data performance on AT&T networks of the international version. It seems people have concluded that certain functions may not work but that generally 4G LTE speeds and network reception should be the same.
Is this a good summary? I would love any thoughts or advice on deciding between these two models.
Thanks.
Exynos International all the way, faster phone, unlockable bootloader with a couple of settings changes, more development support
I own that phone and there is no battery drain running the latest firmware
Thanks for the quick feedback. Do you run that phone on AT&T with no issues?
Is Samsung Pay usable yet on that phone?
I was in the same position and went with the AT&T version. International version (G930F/G930FD) does not have full band support for AT&T (no 29 or 30), no Samsung Pay, and no Wifi Calling/VoLTE.
I had an international S6 and would lose connection at times. The lack of Samsung Pay was also annoying. The lack of bloatware was nice but you can uninstall/disable most of them.

No, I'm in the UK, sorry didn't realise you wanted to use it on AT&T, just wondering between the two different models
If you can get full support for AT&T's services, the Exynos would be the best option
The axynos ones are cheap on ebay, but I can also buy an unlocked US version from Samsungs website.
Can you advice me on this?
I'm coming from the LG V20 side with the unlocked US996 model, and just looked at the non-existent G6 forums so please keep it in mind as I say this: I will never ever ever buy a major branded Android phone unlocked, ever again.

? Why ???
The exynos have an unlocked bootloader, the "unlocked" other version only has unlocked sim. The exynos will allow root, however root trips knox, and therefore breaks Samsung Pay.
I'm using a UK version and it's pretty flawless. Samsung Pay works out of the box. I bought it from a UK authorized reseller so its got a two year warranty (in the UK - I pay to ship it there) and BTU is typically in front of the line for updates. It has no bloatware but none of the unlocked versions do. I had a AT&T version first and the Exynos version seems a tad more fluid and responsive.
It has all AT&T's LTE bands except for 30 and gets better LTE speeds than the AT&T version. Do a search, there's a thread on it.
I'm going to sell it when the Note8 comes out and it was cheaper to buy outright and will fetch more when I resell it. I liked it so much I bought a EU LTE Tab S3 to keep it company. It doesn't do VoLTE or Wi-Fi calling but that too is common to unlocked phones.

I want to get a phone with a care plan . Is there something like that in the states?
Hey guys I just bought a OnePlus 8 off Amazon to replace my Pixel 2 XL. However today I noticed it's the EU model IN2013, NA is IN2015, I already knew not to buy IN2010 the Chinese version however I didn't know the US unlocked was a different model because nowhere I looked online mentioned it. I looked at the LTE bands before purchasing it and saw it supports all of Verizons bands (especially the critical band 13) so in theory it should still work right? My fear is when I give them the IMEI to enable CDMA Less on my line they will notice its an EU model that's "not approved on their network" and thus that will prevent it from working even though it supports all their bands.
Now to answer some questions:
Why did I buy this from Amazon instead of OnePlus?
Because it was $100 cheaper and the only way to get the Onyx Black color
Why didn't I buy the Verizon version?
Because it's $100 more expensive than the unlocked and it has a locked bootloader like all of Verizons phones

Hi,
I don't think they won't approve your device. I'm living in France so I don't know much about the Verizon Politics about that. But if they have common sense, they won't refuse just because it's not one of their devices, they may lose a lot of customers if they did so. There's a Verizon model to support their 5G, but for LTE it's all good.
In France, no carrier would dare doing that, because everybody buys their phones on internet, already unlocked and stuff...
There's a huge competition between carrier so they won't dare to be so restrictive on who can use their network or not. It'd be like "if you want to give me money, you have to pay me at least 600$+60$/month, who do you think I am, I'm not accepting just 60$ every single month", that makes no sense, only Karens thinks like that.
So LTE is cool, but I can't say that for the Verizon 5G
Hope this helped
I already knew 5g wasnt going to work but I don't care because Verizon uses mmwave 5g and that's not coming to my area any time soon. I just want to make 100% sure LTE works, right now I'm 90% sure but that IMEI thing has me worried, Verizon only allows approved devices on their network (absolute BS imo, if it supports all your bands it should just work). I don't know if they support only the American OnePlus 8 (IN2015) if so that would suck because hardware wise the IN2015 and IN2013 are virtually identical from what I could find with only a few bands missing from the IN2013 but they don't matter for Verizon
