Unlock to use on any carrier? - T-Mobile HTC One (M7)

The Dev forum has a neat tutorial to unlock your phone through Htcdev.com.
Noob question: does this mean you can use an AT&T One with T-mobile and foreign carriers?
Also, the AT&T One includes all the LTE bands covered by the T-mobile One. AT&T also includes most HSPA bands covered by T-mobile One.
Does this mean AT&T One can use HSPA and LTE on T-mobile?

The unlock on htcdev is for the bootloader, not carrier unlock. To carrier unlock an AT&T phone you would need the unlock code from AT&T which they would give if you purchased the phone at full price (not sure why somebody would that when you could order the carrier unlocked version directly from HTC which would be bloat free; the only reason to do that would be the fact that you can get AT&T HTC one much faster than carrier unlocked from HTC/Letstalk)
You are right about the AT&T one and T-mobile both capable of LTE on both carriers. But both the AT&T and carrier unlocked phone from HTC lack the 1700 AWS HSPA T-mobile band, so those will get 3G/4G/HSPA only if you live in a T-mobile 1900mhz refarmed area (and speeds on that 1900 refarmed spectrum seem to vary from person to person or place to place)

I unlocked mine from a seller on eBay, $13. I got the code in less than 1 hour.

You can unlock your Note 2 without root and without paying. You'll have to downgrade to 4.1.1 regardless because T-Mobile and other carriers put a block on 4.1.2 (I know this because I just got rid of my Note 2 and had to find all this out through a lot of searching. The unlock code I ordered was correct but wouldn't work until I downgraded.)

If you paid the full price for this phone, you can just call Tmobile and they'll give you an unlock code.

Don't forget that voice goes over AWS *exclusively* via UMTS/HSPA in markets that either have no 1900 licenses or very bad 1900 coverage.
It pisses me off that they are *STILL* splitting bands between carriers... It really wouldn't take that much to make a universal GSM phone... Tha being said, it *may* be possible to unlock the AWS frequency in the future - that is, if all the internals are the same between the devices. It wouldn't surprise me if it is gimped like the T-Mobile S3 got gimped in terms of LTE support.

Of course it's not hard, especially with current gen basebands, to support a full range of UMTS frequencies. Network operators get OEMs to restrict bands to make buying their subsidized phones less desirable to other operators, i.e. it makes it harder for someone to move from AT&T to T-Mobile. This is an easy business decision for the operators and OEMs don't seem to care much, since I doubt many consumers even know that they should expect their GSM phone from AT&T to work on another GSM network. I remember some people on twitter earlier aptly likening it to DRM--its only purpose is to make their customers' lives more difficult. The fact that Google has supported pentaband UMTS on the Nexus 4/7 and Galaxy Nexus is a great reason to love them, but I digress.
As for granting UMTS over AWS to the AT&T One, it seems pretty unlikely. It's already been shown to be not as simple as a radio flash, and I haven't heard of anyone successfully adding new bands to MDM9x15 devices the way they did with earlier basebands like on US GS2 variants. It's possible that there is some obscure configuration point in our firmware somewhere that will enable such support--and I'm sure there are people out there digging--but I'm not holding my breath, personally.

Oh I agree with you completely but stranger things have happened like at&t S3s having hidden AWS LTE support... all it takes to activate is a special ROM/radio/bootloader/recovery set that T-Mobile made to test their LTE network... flashes right over the I747 via Odin and unlocks AWS HSPA and LTE. And the Nexus 4 AWS LTE hack too.
Its still annoying... I think we will start to see more compatibility coming up though for roaming revenue purposes... At least between at&t and T-Mobile. I guess we will see. I am waiting to see what comes of the mysterious LG D810 that is running the Snapdragon 800 before deciding on my next device but I'm almost 100% sure I will be passing the GS4 up though.

I thought you could not factory unlocked phones in the USA that were manufactured after Jan 26. 2013 unless the carrier unlocked them? Or is this over now because I'm getting my ONE today and was curious

The OP is talking about Bootloader unlock, you're talking about network unlock. It's not illegal to get network unlock if it is through your provider, I believe the whole no unlocking thing has more to do with 3rd party unlockers.

Anyways if the government told you that it's against the law to unlock your toilet so you could take a $hit, would you listen to them or would you just unlock the door and take a $hit anyways? I'll choose the latter thank you

I know the two actions are completely different. My point was that a law against unlocking your mobile device would be as stupid as not being allowed to perform a regular "bodily function". It's just a stupid law that was lobbied by the contract sucking mobile carriers. The actual phone manufacturers could care less. Another example is: if you buy a car and have it financed then being told you can't add custom wheels or exhaust system. That's a good example right?

Look, I don't particularly like the rule, but if I need my phone unlocked tmobile will provide a code. The carriers subsidize the phones, even tmo through their zero interest loans. So from their perspective it makes sense.

T-Mobile isn't subsidizing AT ALL now, you pay full retail for any device. They should *HAVE* to provide unlock codes right off the bat.
And they do -
Devices Purchased at Full Retail Price
If you paid full retail price for an eligible device:
T-Mobile will provide the SIM unlock code as long as:
Your T-Mobile account is in good standing; and
The device has been completely paid for (you must fax the proof of purchase to T-Mobile).

They are subsidizing the cost of the loan. The unlock is only available if you have paid the phone off.
They are charging zero percent interest on a consumer item.

Need unlocked code for T-Mobile version

My girlfriend just bought the HTC radar 4g on craigslist but her service is with at&t. If anyone has the unlocked code and could share it with me would be great.

If you are referring to a SIM unlock code, there is a unique code for every IMEI. From knowledge you will need to purchase one or find a friend with Tmobile and see if they can request you an unlock code
On eBay sir, they're about 4 dollars, and its a Code Based unlock based off the IMEI number. Don't always count on full functionality, as some bands are different.... But Phone calls and TXT should work perfect.
Just got mine unlocked this week in fleabay for less than 2 bucks.
I had T-Mobile unlock mine. And I can tell you that the Radar works great on AT&T. My data speeds are between 4 - 6 mbps. Either HTC was kind of sneaky putting in the AT&T bands, or T-Mobile was less than forthcoming about the specs of the phone.

Neither is true. The 1900MHz UMTS support is declared right on the Radar's box.
True. And the information is out there - if you know where to look.
But notice the difference between the phone's specs on T-Mobile's website and on the HTC website.
The T-mobile site only admits that the 850/1900 GSM bands are there. The only UMTS bands they list are the 1700/2100 -Mobile AWS frequencies.
The HTC site reveals that 850/1900 is supported in both GSM and UMTS.
You will see this listed in almost all of the T-Mobile material and it was quoted that way in most reviews.
It's not a big deal - what does it matter to someone buying a phone from TMo? It's just interesting that they omit this little detail in their promotion.

Confusion about the term 'unlocked'?

Hey all...
A friend of mine would be visiting the US next month. I was thinking of ordering the DNA at a full retail price (obviously). But this term of 'unlocking' confuses the hell out of me.
What does it actually unlock? From what I read, it is already unlocked and can be used with ANY SIM around the world. So, my friend just walks in to a store, buys the phone and gets it here in Delhi, India for me, I pop in my SIM card and everything just works fine.
Is that right?
Do I need to be aware of something that might not work. There is no 4G here yet, but I use 3G. Will that work?
Everything from 3/2G, MMS, calls, Msgs...everything will work just fine right?
THANKS!
Most of the unlocking in the DNA forum is referring to the bootloader. Since Verizon is the Anti-Christ of cell phone carriers, they don't allow phones to be sold with an unlockable bootloader. However an exploit was discovered that allowed HTCdev (website to that is used to unlock non-Verizon/AT&T HTC phones) to see the Droid NDA as a different phone and then unlock it.
The phone is GSM unlocked out of the box. Meaning you should be able to put your SIM in, plug in your carrier's APN settings, and theoretically be able to use 2G/3G/MMS/SMS/Calls. However, I'm not sure what frequencies carriers in India use for GSM and if the Droid DNA supports those frequencies.
There are some CDMA carriers in India I believe. I don't know what steps need to be taken to use the Droid DNA on them or if that is even possible. (I don't think it is)
(if I did a bad job of explaining it, or got some details wrong, someone please correct me)

Thank you sir for your reply...however, I didn't get the last line about CDMA bit. Is the phone CDMA or GSM. I don't care for CDMA devices as of now as I am never going to switch. Also, is there a way to find out about the frequencies you mentioned...?
And, what about the price. What should my friend tell the rep? As in, wha phone is she looking for, locked, unlocked, carrier unlocked?

Verizon Samsung Galaxy S4 to have AWS 4 Band (Tmobile LTE Capable?)

Hi,
So I've read the FCC documents located here: LINK
Page 1 and Page 5 are the most interesting! These state that the Verizon model SCH-i545 will have AWS band 4 (of course 13 too) which does support T-mobiles LTE network right? It never states 1700/1200 frequencies.
Thing I want to know from the pros is will this phone indeed offer LTE support for T-Mobile or and I'm just seeing things?
Also, for all the other people that are wondering if the ATT model will offer LTE support for T-Mobile as well? It will since it supports both bands 4 and 17 But wait is that AWS band 4?... the jury is out on that! -_-
Many Thanks

If I am correct, Verizon phones do not use sim cards (CDMA) and AT&T and T-Mobile are GMS (sim phones). So even if the bands are supported, I don't see how a Verizon phone would work on T-Mobile or AT&T unless they are CDMA / GSM dual phones. And even then they would have to be unlocked.

All of the major Verizon releases over the past year have come GSM unlocked. They are world phones that contain GSM and CDMA radios. I'm using a Verizon iPhone 5 on the Straight Talk (AT&T) network currently.
All lte phones have sim cards as it is a gsm technology. My girls verizon gs3 has a sim. As far as it being compatible that is a hell of a question.

Hey this is one question i have lingering on my mind. How is the StraightTalk connection? Is it any good? Are there call drop issues? And do they have data plans?
if i buy a tmobile s4 will it work on verizon??
I know most things are under the catagory of speculation/rumor but i was wanting to to check out tmobile network for a bit.... the no contract is appealing. If i bought the phone outright and ending up not liking tmobile i would switch to verizon. Short of selling the tmobile and getting a verizon phone i was wondering about just activating the same phone on verizon?
Will there be "one phone" in US or would they all have thier own modem chips i guess is the real question....
thanks for the guesses and speculat'n!
You have to consider its Verizon and they have 700Mhz LTE and you can't roam on AT&T's 700Mhz so I would not expect to access Verizons AWS spectrum on T-Mobile or vice versa. Remember when they said LTE was the unifying spectrum to allow for easier use across networks and carriers, well that was a pile of BS.
Great news, but I heard verizon was purposely going to burn in their logo onto the amoled screens.

Wrong: those "700mhz" frequencies are different bands. Both T-Mobile and Verizon are building out LTE on the same band: 4 (AWS). They will be interoperable device-wise.
AT&T also owns a lot of AWS, and though they're currently running LTE on it only in one market (somewhere in Oklahoma IIRC), all their LTE devices do come with band 4 enabled.
The more I read about the differences, the more I'm convinced that the Verizon model is more cross compatible with all other services. It's still the only CDMA model. But it's also gsm unlocked if you know how to program APNs. Any thoughts?

if we ever get to the point where we don't need 3g at all any more (CDMA) and we can get VoLTE and use the LTE band exclusively that will eliminate a lot of the incompatability between Verizon and GSM carriers .

When we get to that point, Verizon will basically be a GSM carrier. Considering LTE is just an evolution GSM, both developed by 3GPP.

Not just Google...all the manufacturers could do it. But...don't get your hopes up. That situation is not in the carriers' nor major manufacturers' interests, and they sit on the standards bodies. No one represents the users/customers.

Sorry it took so long, but VERY minor differences. Icons and little things like that. Software updates show up faster on Tmo vs ATT and if you are looking to root...well go for the Tmobile version. Also, technically when you buy a device at full cost, they have to give you the unlock code. But it all depends what provider you are going to use it with.

Sorry it took so long, but VERY minor differences. Icons and little things like that. Software updates show up faster on Tmo vs ATT and if you are looking to root...well go for the Tmobile version.

If both have root why go with T-mobile I see the at&t version can be rooted as well just asking because around me they are in Stock at at&t and not t-mobile

IMHO, software updates always seem to be faster on Tmobile. and to avoid an unlocking headache, just get the Tmobile one. I ordered online and had it in 2 days.

Would I be able to pair the T-mobile gear with T-mobile service to my vzw phone?

Only if verizon unlock your phone. Usually vzw phones are gms unlocked for international travelers but they dont want to accept US sim cards.

AFAIK , the verizon and sprint variants dont even have sim slots. someone correct me if im wrong.... samsung has made it a PITA for the international traveller and this watch, the hardware supports all the bands but for whatever reason they split up all the variants and made each watch support different bands.

Will this work? Verizon M8 --> AT&T fo-'official'?

I have an old M8 lying around that I fired up and had remembered I had rooted it and the bootloader is unlocked.. Is there a way to 'trick' this phone into thinking it's an AT&T branded phone? hboot, etc. and that will allow me to RUU something official from AT&T? I know this sounds really strange and probably stupid but.. I just can't sleep and need something to fill the time.. Can I do it?
Don't think so, radio hardware is different, not to mention the partition layout.

Absolutely not. At least not any way that is known; and your chance of failure is high (with a brick being the possible or even probable result).
As mentioned in the previous comment, the partitioning on the phones is different. If you try to run the RUU, you at best it will fail, at worst it will brick the device.
Most other M8 versions (that don't support CDMA) can be "converted" from one version to another (other exceptions being dual SIM and M8 Eye). But Verizon and Sprint are the oddballs here. Some experienced devs have been messing around with these variants from the start (to try to convert them) with no success.
Perfect! All I needed to hear! Ah well.. it was worth a shot! Just trying to get my account provisioned for LTE so I can get LTE on my unlocked devices.. I've been told, and read, that if I can get an AT&T branded LTE capable phone to just swap my SIM in it.. and let my account provision, then I'll have LTE on any device AT&T or not... Just trying to avoid a contract..

As long as the phone is SIM unlocked (Verizon version is) then you should just be able to put an AT&T SIM in, and enter the proper AT&T APN for service, as long as the phone supports the proper bands. Its irrelevant whether the phone is AT&T branded or not.
Now the underlined bit in the paragraph above is the main issue. The Verizon M8 only supports one of the four bands (Bands 2, 5, 4, and 17) used by AT&T for LTE (Verizon M8 supports Bands 3, 4, 7, and 13). So depending on what band is used in your area, you may or may not get LTE.
But GSM (2G) and HSPA (3G) should work just fine on AT&T.

That's the odd part.. My main phone is the S6 Edge from Verizon.. it's on the AT&T network and I assume my APN is correct.. But it's not picking up LTE and I am almost certain the S6 Edge from Verizon will pick up the correct band for AT&T LTE .. But it's only using the H+ speed.. What's even more strange?? When I throw my SIM into the M8? I get LTE on AT&T and verify with 30+mpbs speeds.. I have no idea what's going on...

Yeah, that is strange. According to the specs for the S6 Edge here, the Verizon version supports the same LTE bands as the VZN M8, and actually some additional bands (2 and 5) that also happen to be bands used by AT&T.
One thing I can think of, is that the VZN M8 in actuality supports some bands that are not advertised/explicit in the specs. It wouldn't be unheard of, as members here have reported some versions of the non-CDMA M8 as supporting some bands not indicated in the specs. And that band happens to be what AT&T is using in your market region. In this case, that band would seem to be Band 17 (the only band that AT&T is known to use, that isn't listed on the S6 Edge specs).
Or the other possibility, is there is just some issue with the S6 that is preventing connection to LTE (but on the same supported band that the M8 has).

Yeah.. I'm not worried about it.. I've been told that all I need is an AT&T branded LTE capable device hooked up to the account and that my account hasn't been provisioned for LTE .. I've seen this in a few places so it's worth a shot.. I ordered a junk LTE phone branded AT&T to test it out.. ordered a OnePlus 2 and will likely unload the S6 Edge (if it never picks up the LTE from AT&T)

As I've already mentioned, its not really necessary to have an AT&T branded device. I suspect the reason you've seen people say this, is that AT&T branding means by definition the phone has all the bands used by AT&T for LTE; since obviously the phone is intended for use on AT&T's network. Since AT&T uses a number of bands (4) and LTE bands being used worldwide has become very un-standardized, its somewhat difficult to find a non-AT&T phone that has all the bands. But they do exist, such as the US unlocked M8, Dev Edition M8, and Nexus devices. Also, I've seen folks used other non-ATT branded phones, which may not have all 4 LTE bands used by AT&T, but the one(s) needed in the particular user's region. Not ideal, but sufficient for some folks.
Another reason why some may say the phone needs to be AT&T branded, is that AT&T tech support won't provide you any support if you have a non-ATT phone. But honestly, I've used non-branded devices (and plenty of folks here have), and this is very rarely an issue. The folks here on XDA will usually provide you better support, anyway!
Of course, your ATT account needs to be provisioned for LTE in order to have that service. Its a simple matter, and doesn't cost anything (just need a smartphone data plan).

I've dug deeper and have to not only have an AT&T branded phone, I have to register the IEMI on my account, then swap the SIM card back into the other phone. I've got the phone but can't find a way to do this online so I'll have to call tomorrow...

Absolutely NO.
What I mentioned above (Post #3) for the Verizon variant, also applies to Sprint (both versions support CDMA - the fact you don't use it is irrelevant). If you try to convert to another version won't work, and will probably result in a brick.
Also, even if you didn't have a CDMA version M8, you typically can't convert using an OTA, it has to be an RUU.

Absolutely NOT. As already thoroughly discussed on this thread, if you attempt to install another version's radio on the Verizon version, it won't work, and you may radio brick the phone (permanent damage possible).
Different radios, different partition layout.
Don't even try it. Experienced devs have tried to "convert" by various methods and mods, and failed.
But there may be other ways (besides flashing another version's radio) to enable the band(s) you want, read on:

You can take a look at the following method, as it claims to enable Band 20: http://forum.xda-developers.com/verizon-htc-one-m8/general/lte-band-7-2600mhz-finally-guide-t2992523
Read the thread, and proceed at your own discretion. I'm not knowledgeable with changing NV values (it doesn't work on "GSM" M8 variants, so does not apply to me). I simply know this thread exists.

Far from a genius, and I don't create any of these mods. I just contribute by passing on knowledge I've gained here. Really, that is part of what XDA is all about.
