[Q] Use T-Mobile Samsung S4 on AT&T

I plan to buy the T-Mobile Galaxy S4. Worried that I may not be happy with T-Mobile's coverage is it possible to use it on AT&T's network? If so will it be able to pick up all bands?

Yes

So, does the S4 follow the S3? Will a T-Mobile S4 work on all other carriers in the US and Canada, but, just not have LTE speeds (Only HSPA+)?
Thanks!

According to [1] the t-mobile version of the S4 has the following LTE bands: 1/2/4/5/7/17, which correspond to 2100 1900 1700 850 2600 700MHz.
- Bands 1 and 4 are clear, as those are the main t-mobile LTE bands.
- Metro PCS uses band 2, so given the pending merger to t-mobile, this makes sense as well.
- Band 17 is used by AT&T, which would hopefully mean a T-Mobile Galaxy S4 can be fully used on AT&T including LTE.
- Band 7, is commonly used around the world, including Canada, some countries in South America and Asia and many countries in Europe. So this should allow for using the device in many countries abroad e.g. through roaming, or buying a pre-paid sim when overseas on business or holidays.
But why did they include Band 5? According to wikipedia [2] that band is only used by very few carriers around the world. Would it have not made more sense to include e.g. Band 3 (1800MHz), which is commonly used for LTE in Europe and Asia, including most of the European T-Mobile networks. That would have allowed for much broader roaming.
Furthermore, can someone confirm that the information on the webpage is correct and particularly that T-mobiles S4 really has band 7 (2600MHz) included?

Theoretically, yes, it should work on AT&T fine as the device does support all of AT&T's bands, including their LTE bands. Of course it needs to be SIM unlocked in order for you to be able to put an AT&T SIM in it though.

2600 mhz band and is for T-Mobile in European Union
To your question why. .....if they did include this to American version S4 then there will not be difference to international S4 LTE version. ....There is two different devices 9500&9505...it's a market democracy that separate this market for known reason. ....otherwise ....There is going to be way some time on road to flash different modem to give you other bands. ....flashing modem will not make hardware frequency to make changed. ...
Just follow XDA there is a lot of smart people out there that will make them

T-mobile mostly uses the 1800Mhz band in Europe (UK, Germany, Croatia, Hungary, Netherlands and Czech Republic) although it does have some licenses for the 2600MHz band as well. 2600MHz is heavily used by other carriers in Europe though, which is why I was interested to get a confirmation that the t-mobile US version of the Galaxy S4 really does have that band included, as I will likely want to use it in Europe too.

If you go to US tmobile website and go to specification you will see exactly what you looking. ...just remember there is also important to look for given band on frequency you will operate in Europe. ..my note II Was running fine on A1 Austria Tmobile Orange and tele ring company. ...When I was in Europe. ...in Australia I was not capable running LTE be cause I do have 2600 MHZ frequency just no band for Australia. ....
There it pulled T-Mobile
Bands and frequency
HSPA+ Bands: I (UMTS 2100), II (1900), IV (1700/2100/AWS), V (850)LTE Bands: Band 1 (2100), 2 (1900), 4 (1700/2100), 5(850), 7 (2600) & 17GSM Bands: 850, 900, 1800, 1900
So if you looking for carrier that operating on 1800 it will support only GSM .......GPRS data
On other frequency you should pick high speeds data
This are A&TT Baseband and frequency from Samsung site
Frequencies and Data Type: LTE: Bands 1/4/7/17; HSPA+/UMTS: 850/1900/2100MHz; GSM: 850/900/1800/1900MHz*

Ah, looks like they have updated their page to include more details now. When I looked a couple of hours ago it still only said "LTE compatible" with no indication of the exact frequency and bands it supports.
As the specs on t-mobile.com and samsung's us page now match in claiming it does have support for band 7, I'll assume it actually does. But given that the AT&T page still claims the S4 has FM radio and the supported LTE frequencies of the AT&T spec page don't match the Samsungs's spec page, it seems even the "official" specs can't always be trusted.
Thanks

Here is what the Canadian versions use:
GSM Bands:850/900/1800/1900
HSPA+/HSPA Bands:850/1900/2100
LTE Bands:2100/2600
So the T-mobile version should work no problem in Canada if we end up with a bootloader locked version up here.

Well, it looks like the Tmobile version of the S4 may be the one to get for a lot of us on ATT and in Canada since it has the right bands and the bootloader isn't locked. It just needs to be sim unlocked.

i am very interested in this option. I guess what we need is some confirmation from folks in the field/first hand experience.
I guess we need to wait for someone to sim unlock and test the LTE?

Is the Canadian version confirmed to be SIM locked (the same as AT&T)?
Thanks!

Is the sim on the T=mobile version a micro? AT&T uses full size sims. Of course, getting a micro-sim from AT&T or using a sim cutter should work, but it is still a consideration. It also needs to be determined if the radio (software baseband) of the T-Mobile S4 takes advantage of the Hardware frequencies the phone supports. In other words, will it be optimized for AT&T networks.

The next important question is - how do you SIM UNLOCK the T-mobile S4?
If T-Mobile doesn't give you the unlock code, then this is moot.

SIM locked it would be as always. Bootloader locked no one knows yet. SIM unlock on previous Galaxy devices has been done for free, or for a minimal cost.

I want to buy it from a US Carrier be use it comes with US Warranty. I bought Intl Note before and went dead on me...no warranty of course. I know this is rare, but having a dead $600 phone once is enough for me
Anyways, if Tmo won't provide the SIM unlock code (AT&T does), then there's no point buying it from Tmo because the phone is always locked to their network.
I would have bought the phone from AT&T, but the bootloader is locked.

Ouch, that's understandable for sure. I've been lucky that my international Galaxy S I-III are all still running well.
Did you buy it from an online store that claims to have a warranty or eBay or similar?
Sent from my GT-I9300 using xda premium

I bought the Note 1 from Amazon - the seller was selling it through Amazon Prime. When I searched for the International Note, none that I found (eBay, Amazon, etc.) offer a 1-year warranty with Samsung USA.
Interestingly, I used to buy the International version of Nokia phones (remember those good ol day?) and Nokia USA WILL honor the warranty (I have to ship it to Melbourne, FL).
I wish Samsung USA will do the same or have a local Samsung store, like Sony Store so I can buy the phone full price from them and have full warranty. Heck, even Amazon and NewEgg are selling the Xperia ZL unlocked with US warranty! Right now my options are limited (AT&T have locked bootloader, T-Mobile SIM locked, I don't want CDMA phones).

HTC 10 International Version with AT&T (M10H)

Will it work with the LTE bands?
The seller on eBay say's it fully works with AT&T and T-Mobile?

HTC 10h (International version) WILL NOT work on US LTE bands
If you go to this page: htc. com / uk / smartphones / htc-10
scroll to the bottom where the specs are and look under "Network" you will see the differences between the radio bands supported by the International/Asia and the America versions of the phone. The International version DOES NOT support all of the 4G LTE bands used by ATT in the US.
This page shows the LTE bands used in the US by major carriers. phonearena. com / news / Cheat-sheet-which-4G-LTE-bands-do-AT-T-Verizon-T-Mobile-and-Sprint-use-in-the-USA_id77933
LTE band 5 is on both models of the phone, and band 5 is used in some very limited areas of the US, (but not enough to make it worth having a regional only phone at this cost, and the newest LTE uses dual-bands so that technology wouldn't work for you either).
If you live in the US, you absolutely want the US model of this phone if you expect 4G LTE and newer technologies to work for you over a wide area.
Hope this helps someone... I got suckering into ordering an International version off Amazon and it would not work on AT&T 4G LTE in my area (band 2).
Better to order the US version directly from HTC.

Does the opposite work? I mean, does the US version work in Europe or not?
I'm asking because the color I want is only available in the US and I live in Europe.

You should check which LTE bands your European carrier is using. Just google it "What LTE band does [your carrier] use in [your country/city]."
The US version supports all LTE bands except 8 (Saudi Arabia) and 32 (no idea where that's used..). en. wikipedia. org / wiki / List_of_LTE_networks

Hello, I have the same problem...How you solved it?

If you load the US unlocked on the international phone, you will pickup some LTE bands. I seem to be able to pickup 4/12, but not 2 with Tmobile

Hi I'd like to know if the US unlocked version of the HTC 10 (that you can order by the official HTC USA site) works on the Italian networks: band 3(1800MHz), 7(2600MHz), 20(800MHz);
so if I buy this phone and I do it to ship from America I can use it in Italy with any networks problem or restriction.
I'm very interested to know this, thank you.

m10h will not support 2/4/12 unless you convert to US unlocked. I have m10h and am on US unlocked. I seem to pickup 4/12 in some parts of the country, but have yet to see band 2. I'm also skeptical that I get all of band 4, I'm thinking I only get certain frequencies of Band 4.

So which version should I buy to use on AT&T in California?

Can anyone make sense of this conversation I had with u.s. cellular?

Hello. Does the LG K8 prepaid phone come unlocked? domestically or internationally or both or none? Thanks.
The that device is unlocked but it isn't a world phone and it can only be used in the United States. ^Andria
Hi thanks for that reply. But in saying that if it is unlocked and it is used overseas on a 2g or 3g or 4g band that the phone supports it should work?
It's unlocked for use with another U.S. service provider but it can't be used abroad because it doesn't have world phone capability. ^Andria
What I can't figure out is does she mean its domestically unlocked but internationally locked? ( that wouldn't make sense would it?)
Or is she clueless or trying to bs me in how I said about the frequencies?
Lol.

She means it doesnt have the bands that support overseas countries.

FYI, oneplus chat support referred me to willmyphonework.net. i ordered the north american version to a usa address. its getting shipped to me in tokyo for $26 USPS (6-10 days).

I bought the European model and will have a chance to test in Japan when I get back in September. Will be flying back to Europe for holidays.
As long as your phone supports the 2100Mhz (B1) band it should work (as far as I can tell, I sure hope so otherwise my oneplus would be useless hehe). Coverage in the country side and mountains might be poor but my Ymobile pocket wifi always had crap reception in the mountains anyway so no big change there hehe.
Edit: I believe the USA is a bit special when it comes to the frequencies used. Unless you are from the USA you might be better off when the European model as that seems to have better global support.

North America version ordered from and shipped to USA, then forwarded by post ($26, 10 days) works fine with data sim. I don't have a voice sim here in Tokyo to try.

Am I right to assume this means it comes with GSM out of the box, with modifications for CDMA depending on which country I am ordering it from?

Simply check which bands are available in countries you intend to use the phone in and compare that to supported bands.

So to clarify, let's say I am travelling to Singapore for instance, and they use GSM, I will be able to use my N. American version right because it also supports GSM along with the CDMA.

Exact frequencies of bands used are also important. The phone does support both GSM and CDMA, but you need to make sure it supports the right GSM bands.

So for example, GSM Arena shows a GSM band of 900 and 1800 in Singapore. That means it will work right? And thanks for taking the trouble to answer these newbie questions.

Yup, those bands are supported. 2G at both freqs and 3G and 4G at 900. So you're good to go
