[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).

[Q] HTC Desire Eye models

Hi all,
Had to pick up a Desire eye without having done much research (my Sony Z3 died while travelling).
My Desire eye was bought from Taipei airport, and is marked as a M910x. It lists the lte bands supported as 700, 900 and 1800.
Based on GSMarena and other sources, it seems to suggest more support than what the box does.
So does anyone know with certainty whether:
1. My specific phone only has those 3 bands (strange)
2. Region specific branding, but has more bands.

For what its worth, over the weekend I was in Manila, Philippines, and connected to Smart LTE, which, based on my previous experience, should mainly be 2100mhz LTE, and my phone appeared to connect just fine. So it appears it may have more band support than the box suggests.

For anyone who may be following this thread, the Taiwanese page for the HTC desire eye reports the same bands as GSMarena:
4G LTE：
FDD - band 1( 2100MHz) , band 3 (1800MHz) , band 7 (2600 MHz), band 8 (900MHz), band 28 (700MHz)頻段
TDD - band 38 (2600 MHz),band 39(1900MHz), band 40 (2300 MHz),band 41(2600MHz) 頻段
Not sure why its listed differently on the box.

I decided to call HTC's Taiwanese customer service hotline this afternoon.
It took the girl a few minutes to get the details, but her official response is that the bands listed on their official website is correct, and that the box is only stating the LTE bands that the Taiwanese networks will be launching shortly. i.e. domestic market labelling

Hi all ;
I bought a HTC Desire Eye M910n model in Turkey , Red/White , and yes it does support 4G.Well tomorrow the mobile will be delivered , i made a quite deep research before deciding to buy this phone and for a mid range phone , the specs seems to rock in most of the cases.This one will be probably my 67.th mobile lol :=) I am also an IT guy .I am pretty sure that i would love that phone . But as you all know electronics is sometimes about being lucky or not ., so i will see that in the enar future and let you know .

T-Mobile bands...

I'm VERY concerned about buying this phone now. T-Mobile have only listed LTE bands 4 & 17 on their site.
International
Quad Band GSM; LTE: 4, 17; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)
What in the eff?

Des just answererd this question on Twitter: https://twitter.com/askdes/status/581568102015569920
It has:
GSM - 850/900/1800/1900
UMTS - B1/B2/B4/B5
LTE - B2/B4/B12/B17 with CA + B3/B7 roaming
This is the perfect T-Mobile phone.

So the T-Mobile version does not have 1700, and is therefore identical to the other models? Do we know if it includes wifi-calling, or if we would be able to flash the T-Mobile ROM onto the unlocked dev version?

It does have 1700! That's Band 4, and for both LTE and HSPA.
The T-Mobile version also supports WiFi calling and texting. I have no idea if the T-Mobile firmware can be flashed to the unlocked version, but I don't see why it wouldn't be feasible.

T-Mobile (Des) confirmed: 2, 3, 4, 7, 12, and 17
AT&T lists: 2, 3, 4, 5, 7, 12, 17, and 29 (adds +5 and +29)
HTC Dev & Unlocked versions (per HTC on Twitter): 2, 3, 4, 5, 7, 12, 13, 17, 29, 30 (adds +5, +13, +29, +30)
Maybe the T-Mo phone supports more that could be unlocked, who knows. The extra bands aren't useful to me.

Sorry, but I just want to clarify.
Do all versions of this phone support BAND IV UMTS or not?

HTC has done this on the past couple of phones. Only the T-Mobile phone will do their specific bands (HSPA+). On past models I don't recall anyone getting the ATT/DEV models to work with those T-Mobile bands. I don't believe we ever found out why. Some speculated it was due to cost to license all the bands, or that it is actually different hardware. The M7 and M8 were both like that.
If you are on T-Mobile, I'd get the model specifically for them.

Oh yeah I remember my Dev version being like that. Fortunately, I live in an area that has been upgraded to mostly lte. This was actually beneficial for me and maybe others in the same situation because it actually saves battery life when the phone isn't constantly switching between edge, 3g/+, and lte. I'm sure many others have been in an area that's barely out of lte but still within h+ range and it's still slow as edge or even slower.

Yes, it is OK if you live in a major area that has lots of LTE. Here just north of LA, I get into the other bands pretty frequently.

I am not sure this was answered? Do all versions of the HTC one m 9 support band 4 UMTS? Many ATT carrier unlocked models are for sale and no one seems to know if they will pick up the UMTS 1700 band 4 on T- Mo?

They will not pick up the T-Mobile specific bands, which use 1900/2100 for 41bps speed. They will work with the T-Mobile LTE band.

Wow, still a mystery. I have the AT&T SIM Unlocked One M9 and I have a TMobile prepaid SIM and get Edge, 3G, 4G, LTE Band 2,4,12...I cannot find an app that shows the actual WCDMA (4G) Bands ? But, it notates 42 MBPS when it says HSPA+ 4G using Network Signal Info-Pro App..and also shows 384 Kbps when it says 3G....
So, seems Des is correct unless the Network Signal Info Pro app is wrong?

I turned off everything except WCDMA, and this is what I get being reported by LTE Discovery. HSPA+ @ -113. I have a ATT unlocked M9. I do have the T-Mobile 2.11.531.19 firmware installed as well as the T-Mobile rom.
Using XDA to unleash the power of Android on my HTC One M9

Thanks but as I mentioned I cannot find an App that shows the WCDMA Bands to confirm. As you can see even LTE Discovery says N/A for DL and UL Freq...when on WCDMA...
The only App I can see that helps is Network Signal Info Pro...and unfortunately it is limited and shows me the below in my market;
HSPA+ 42.2 MBPS
HSDPA 7.2 MBPS
UMTS 386 KBPS
But, does not indicate which Band or Frequency ?
Anyone know of an App or Command that will show WCDMA Bands???

About the international m9 edition sold in China soon

Edit: HTC China has significantly increased the price of m9 Chinese international edition from approximately $640 to about $705. This makes the Chinese edition m9 not so attractive compared with the US unlocked one.
BTW: the Chinese international edition is usually the same as unlocked versions worldwide. I say so because the international edition is completely compatible with China Unicom, which carries out the same bands as AT&T, and further more, although Chinese edition m8 just contains 16GB internal storage, it could run any international ROMs after being unlocked bootloader.
I am curious if its hardware is completely the same as the American unlocked edition. If so, it will be worth to have a try, especially considering the price which is just ￥3999. The price approximately equals $640 and of course, it has included consumption tax already (Variant taxes of goods are usually not listed separately in China ). Additionally, HTC China also promises that all the customers who have purchased mobile phones of m9 series (m9 and m9+), will be granted HTC Advantage service, as which has been applied in the U.S since last year.
However, the advertisement page also says that the potential customers have to enroll/pre-order firstly during 13th to 20th this month, and then seize the chance to make purchases on 20 March eventually. It is still uncertain that whether the promotion will be held like the mode of Xiaomi, which is another Chinese local brand and has been well-known for "Hunger Marketing" as well.
By any means, I'd like to keep an eye on it.

No the hardware will be different than. Due to mainly the cell frequency that are used. I also heard the chip will be a different chip like the other m9 they released there.
Could be wrong. Even known to happen a time or two.

Thanks for your detailed explanation, but I figure the "international" one might be the same as the unlocked one in the US. If a mobile phone manufacture says it will release an international edition mobile phone, it usually means the bands China Mobile will not be entirely supported. Fortunately, I'm a China Unicom user and also going to travel abroad later, so whether it is compatible with China Mobile is not really my concern.

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

Same Problem

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.

Thank you very much :fingers-crossed:
I'm very happy to know this, I think there are also no problems with the 4g/LTE networks in Italy; I have a few questions if you want to answer me:
Why did you buy the HTC 10 USA version? (and not the Italian too)
Where did you buy it?
Which color is it?
Thanks for the reply

Are you saying the M10H won't work with T-Mobile LTE? Im prepared to S-OFF and install whatever. The vendor listing has the US LTE freqs listed. Is that innacurate?
Listing is here....I'll be so LIVID if its another copy/paste bs item description!

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?

Are you on T-Mobile? Have you used device in Colorado? I have my M10h coming today, I might just keep it with limited LTE and spring for the US Unlocked version from HTC, keeping the M10h as test dummy for my arm64 Debian experiments...

Yes, tmob. I have used the device in NC, VA, MD, DC, NJ, and NYC. Only in NC and parts of VA can I not get LTE where I should be.
