[Q] Milestone 2 (GSM) on At&T - 3G Works?

So, I was about to buy this phone and use it on At&t in the US, but as I was looking at the ebay listings, I noticed that some of them stated that It does not work GSM with at&t.
I'm not very tech savy, but I find hard to believe that such an advanced phone would have this problem. Can anybody that tested it, shine some light on this for me please?
Thank you

It has the hardware to support it but it's the software that verizon has locked down to not work with any other carrier in the USA
In normal gsm phones you simply need an unlock code for the phone to work with any other carrier then the one it's meant to work with but in this case even after you give the phone the unique code it still won't work with att or Tmobile in the USA so we are looking to see how to disable the lock on USA bands on the phone but it seems not many people have made much progress

Thanks for trying to help, but that is not what i'm asking
I know it works, but everybody says it doesn't work on 3G, just on EDGE.
here's the response I got from an ebay retailer
"This version will work on the AT&T GSM network, however, will not work on the 3G network, only edge.
Best regards,
Communication Telecom International "

AT&T uses 850Mhz and 1900Mhz for the 3G frequency bands and it does support it in the hardware as I was saying, its just that nothing at this point will work not even EDGE because the USA lock overrides anything AT&T uses.

You are confusing the Droid 2 Global with the Milestone 2. Two different phones here.

the milestone2 should have the right hardware to connect to att 3g sorry for the confusion

The Droid 2 Global and Droid Pro also have the hardware to support US GSM bands but it has been disabled in the radio. This is not software, so to speak, but rather hardware configuration.
If you know where to look you can fix this problem.

feel like sharing?

i think he is messing look at the username.

Don't hijack the thead!
OP asked about Milestone 2, not Droid 2 Globlal.
So - to address OP's question - yes - Milestone 2 currently on sale in most places is the EMEA model (Europe/Middle East/Asia), which has 900 and 2100 W-CDMA bands only.
Based on the official page from Motorola here, Milestone 2 A953 has a version with W-CDMA 850/1900/2100 MHz which are the bands used primarily in the Americas (850 and 1900) and Australia (850/2100). There was an article the phone is coming to Argentina before Christmas, so it may start showing up quite soon.
If you want US 3G support from Milestone 2, you have to wait for one of these to emerge. Sure enough it will not have any restrictions against US GSM/WCDMA operators (MCC 310) like the Droid 2 Global (currently) does.

I am not "messing". I cannot post external links of proof because I have too few posts.
I also do not wish to SPAM your forum out of respect for the rules.
Search for droidbandunlock on Twitter for more information.

thats sweet then I saw the video, I have a D2G and bought the phone for this purpose, where will the release be?

They inted to sell it as a servce. It definitely works...we were early testers and I have been trying to help them get the word out about it. These guys know what they are doing and what the value of this exploit is.

well sure but I'd like to know about it asap I've been stuck using this on wifi only :/
I'd pay about $10 for it

Those bast*rds!!! How dare they know what the value is and not give it away for free!!!
I am just kidding
People sell unlock codes all the time for like 15 bucks so should be no problem for people that have to pay for this exploit...wonder if it is the same one I found

This may not be the best thread to continue this discussion. My apologies for the hijack.
I am most interested in seeing what you have found, but from what little reading I have done in your threads it appears you are working in the system only and not modifying the radio.
If that is the case, then our exploit has nothing in common with yours.
Do you have any evidence of it working with US GSM bands on AT&T or T-Mobile?
Perhaps we should start another thread, but we will not be revealing the precise nature of our method for obvious reasons.
Our method makes no changes to the system and leaves no trace of itself anywhere that can be accessed on the device itself beyond the ability to use the US GSM bands.

sorry to interruput but i think this is the only way to talk to you unlocker but about what will the price be and where can we find more info about release dates and downloads etc.? i found you on twitter and asked a few questions but there still isnt much info

I have to modify system because in my ROM (Fission) the packages that handle sim card functions do not work without some "blur" components so thus the need to modify my system
I have pics and a vid ready to go for when I was going to sell my service. I am not trying to nor am I going to compete with you guys or from TBH. P3Droid and Gweedo have been nothing but really friendly with me and to be honest; I would rather not deal with the headaches that come with selling a service on this forum and/or many others. I already went through and going through hell for the way I handle Fission ROM Manager and really don't want any more of that crap...I would rather continue dev work on the ROMs and some other apps I have been working on
I won't get into how my method works for the same reasons that are very clear too but if you want to discuss anything in private feel free to message me or hit me up on Gtalk.
Did you guys release your method yet? If not when do you plan on doing so? I would like to prepare Fission for users who will need to unlock or do use their SIM cards...

Thanks Angdroid for ur hard work. Been following u for some time, hopefully u can release SIM package for D2G Fission soon.

Could anyone running Fission ROM try to switch to GSM mode from *#*#4636#*#* menu? I know you can switch to GSM from there on the original ROM without having to go to settings/wireless/networks/etc As it is standard Android tool, maybe that could be used to switch between the two radios until AngDroid figures out how to make it nice. Hope it works though.

Can i Convert GSM TO CDMA ?

Can I convert My galaxy y GSM into CDMA

nope,
thats a hardware thing,
you can't change the radio of your phone

In your dream maybe you could lol

or get a new phone
:highfive:

Yep u can... Change your network hardware things with galaxy y cdma...
or wait... Till i create a GSM to CDMA converter software

Nope
You can't. :beer:

Thats the most impossible thing since its the cellular radio inside the phone and it uses a diffent frequency range
this post is potato friendly

Yes you can and radio has nothing to do with it. I worked at a gsm cellphone company. You can use a cdma on a gsm network. I also worked for a cdma.. yes you can use a gsm on a cdma network. Though it has to be hacked and changed. I'tl void your warranty but yes it can be done.
You have to search hard for it and again radio frequency has nothing to do with it so that is bull.
The phone in part was a factory bought unlocked gsm asus zenphone 2. They wanted to use there unlocked phone on a cdma network knowing it was a gsm.
I told them it's not possible. Sorry.
Well they came back a few days later same phone. I checked the serial ect to make sure. It went from gsm to cdma. He said he got it sent away by someone online who fixed the phone.
Entered a simple from our company and we'll it worked. Not the best signal 3g at best but it worked. He woudnt tell me how he did it other then it cost ALOT.
But it can be done iv seen it in person.

I'd be very interested to learn more if anyone has additional insight. It occurs to me one might be able to swap the radio unit from a donor device if you want to make a "permanent" switch...
On a side note, is it just me or are new tablets coming out with lower specs than they did a few years ago? I'm looking to get a new Tablet, compatible with Sprint. All their offerings are way underspec'd compared to my Galaxy Tab Pro c2014. It also baffles me that nobody bothers to offer a dual radio option, especially considering how (relatively) big devices have become. How much could a radio unit cost at quantity? I suppose the carriers are commissioning the designs to be best suited for their service alone?

Radio Frequencies on mobile phones reply
May be that device was a gsm and cdma when manufactured; and maybe the calling company that sold it first demanded the manufacturing company to lock it on a gsm. It seems that the online guy, who made it work on a cdma, had to only inlock the feature and not hack it’s hardware radio frequency to get it work.

what about honor play COR-L29?

[Q] SM-G900F (belgium) 4G possibility in USA?

Hi guys, i have an S5 bought unlocked in belgium, europe. I had 4G in europe but in the United States it only receives H+. I checked the supported bandwidths with tmobile usa, two of the bands tmobile uses are in fact also supported by my phone (1800 & 1900) yet still it doesnt work. APN setting are already checked and confirmed correct. Sim card is brand new.
Since it still doesn't work, is there a way to flash a USA rom or upgrade something technical so i can get 4G? I would hate to have to buy a new phone again, i just bought this 4weeks ago thinking it would work globally
Thanks again for recommending the best possible option for me at this point...

Most of your questions here were posed and answered in your other thread.
Your 900F model phone is intended for use in a different country. TMobile uses a 900T model. The main difference between the two is that they support a different set of frequency bands. So just like roaming you could use your 900F phone on TMB, but there will be gaps in coverage. You will be subject to more congestion and dropped calls. And in smaller centers where a limited number of frequencies are in use, you may have no coverage at all.
If you never get LTE in a major center on your unlocked 900F, the first thing to check is that you have a LTE capable SIM and that your carrier i.e. TMB has provisioned your account for LTE. And try installing the latest version of firmware for your phone.
No, you cannot simply flash a 900T firmware onto a 900F and have it transform into the other model. By design, Samsung doesn't allow this (to sell more phones and deter carrier churn). There is a hack to add the AWS band to some models. And several threads endeavoring to expand upon that. However they are nascent and would be best described as experimental, dangerous (a good chance of damaging your phone) and with uncertain results as of this date.
Unless you want to put your phone at risk to be a guinea pig, your options are to live with the imperfect coverage or buy a 900T model.
If you want to take a risk, then have a look at this thread. And here. Basically you could use QPST or mzTools 1.21.a to format an edit NV_RF_BC_CONFIG_l to enable additional LTE bands. Enable the parameters with QXDM, then do the actual write with QPST. And /or try writing a raw image of an LTE enabled variant e.g. 900T baseband to your 900F modem partition with the dd utility. This is experimental. It may do what you want or it may brick your phone.

4G 900F in USA
Oké so turns out i am getting 4G just not LTE because of the state i am in. Thanks for trying but what i initially said was correct all S5s are global capable of 4G, just state dependant on the LTE band...

That's not quite true. The chance of damaging the phone is extremely small if you follow the instructions.
The thread to unlock all GSM and LTE bands is here.

Possible GSM Mod ?

I know that the sprint variant of the LG G2 was modded to work on GSM radios such as tmobile.. is there any insight on making this happen on this device ? id love to use this with tmo :good:

Discussion of this has been ongoing in the General forum. The assessment is, despite the implication that there's a GSM band in the Crystal's modem, there really isn't one, and it is impossible to use GSM on the device. Supposedly, the SoftBank model has GSM, but we can't exactly confirm that the Sprint and Boost variants are based on the exact same hardware.
http://www.softbank.jp/en/mobile/product/smartphone/aquos-crystal/ The SoftBank site says it can do international GSM as a world phone, but tests say Sprint and Boost can't. It's not exactly confirmed what's going on.
The device is set up with VoLTE, so assuming the carrier has VoLTE on their 4G signal, a GSM carrier would work just fine, but we haven't seen any luck with it yet. Software block is an assumption right now, so maybe when the bootloader is unlocked, but that's still a ways away. We've not even achieved full root yet.

What LTE bands does Sprint HTC 10 have?

I can't find any definitive answers on this. All I know is the minimum is 25, 26 and 41 but it'd be nice to know the full list. I travel internationally and without other LTE bands like band 7, it makes it tough to use it anywhere outside the US.
EDIT: Someone answered this question in another thread but it would be good to get screenshots to verify this.
m03sizlak said:
LTE Bands: 2 / 4 / 5 / 7 / 12 / 13 / 25 / 26 / 41
I've heard that the FCC filings show that the Sprint variant is not capable (tested or approved) for GSM or WCDMA, which is kind of disappointing since I travel a lot in Canada. Any confirmation on this?

This list of bands is a little better than both the Sprint variants of the LG G5 and Samsung Galaxy S7. If this phone can be unlocked, you at least have a way to go abroad and use LTE connections in much of Europe and elsewhere. Band 7 is the most common band in the world from what I understand.
I'm curious about this comment about GSM and WCDMA. Hopefully someone can verify this one way or another.

Did you ever get an answer on this? I have a Sprint variant of the 10 and am trying to unlock it as I will be travel for the next 2 years. I've done everything I can think of but cannot get the phone's radio to work with any unlocked ROM. I could use some help here. Any advice or information you can provide?

If you plan to travel outside the US during most of this time, your best options are to sell your HTC 10 and get one of the few unlocked flagship phones on Sprint's networks, assuming you want to stay with Sprint.
Here are your options:
Google Pixel
Samsung Galaxy S7 SM-930U
Samsung Galaxy S7 SM-935U
Nexus 6P or 5X
Motorola X Pure Edition
Apple iPhone
Here's a full list as of February 2017 of radio unlocked phones compatible with Sprint.
There are other unlocked phones that are not compatible with Sprint because CDMA and LTE bands are crippled or missing.

Thanks for the response. The thing is I'm not on Sprint and have no desire to be. I won't be in the states long. I bought the phone thinking that like most, it could be unlocked and used as needed wherever I travel to. I knew it wasn't unlocked but figured I could do it myself. Well, I've tried a number of times, and keep having an issue with the radio. Can you explain what you mean by bands being crippled? What I'm trying to find out now is whether it's possible for me to get this HTC10 completely unlocked. I think I've done everything right but maybe not. I'm kinda desperate at this point. I love this phone. And if I have to I'll return it and grab another that can be unlocked but I just have a hard time believing that the phone can't be unlocked. It's a strange concept for me. Any help or info would be appreciated.

First, go go Google and look up what LTE bands are.
Crippled LTE bands = the hardware inside the phone will not allow certain LTE bands to work unless physically altered. It doesn't matter which ROM you install, you will not unlock all the LTE bands without physical alteration. https://www.quora.com/Does-installing-different-rom-change-LTE-band-frequency
So no, HTC 10 will never be completely unlocked. Look at the list above and buy one of those phones if you want a completely unlocked phone.

I'm not sure I fully understand. Yes, I know that different chips have different bands that they work with. So, what you're saying is the Sprint HTC10 variant uses either a different chip or has some sort of other hardware configuration that is incompatible with GSM and the wider LTE bands and that no matter what I do with this phone I'll never have a truly unlocked phone? That's what I have understood, so my best option is to send it back. Ok, I get that. But I have read across tons of forums and threads of people who unlocked their Sprint 10s and are able to use them on other non-cdma carriers. So, how does that work? Are all the Sprint 10s the same or are some more limited than others? Are you essentially saying that i would have to get an unlocked/dev edition of the htc10 to be able to use GSM in other countries?
Sorry if i'm asking stupid questions here, I'm just trying to fully understand this. Thanks again for helping me out on this.

If anyone reading this knows better, please feel free to correct me.
This is my understanding of LTE bands and CDMA/GSM radios.
Phones like HTC 10, which are locked, include hardware that are built for specific usages. Prior to HTC 10, HTC phones built for Sprint's CDMA radio were specifically built to lock out GSM radio signals and most other LTE bands using the hardware. This means you'd have to open the physical device and modify the wiring inside the phone in order to allow other signals to work.
As of HTC 10, the locks are supposedly now just software based but I haven't seen proof of that. What this essentially means is that you should be able to unlock the bootloader and flash new Roms that could allow the GSM radio to work universally. However, lots of people are having issues with it. Here's one story of someone who was mostly successful but still had issues:
https://forum.xda-developers.com/showpost.php?p=68960210&postcount=47
Read through the thread above and you'll see a lot of people having issues trying to fully unlock the radios and LTE bands for this phone.
If you ultimately don't want to be on Sprint anyway, I think you really should consider getting something already unlocked that can universally work anywhere. And lots of interesting non-Sprint compatible phones like OnePlus 3t (among the others on the lists I provided) are already unlocked and have a lot of good capabilities and would work great anywhere. The Pixel is one of the best devices out there and the camera is amazing from what most people say.
So I think your options are limited and I'd highly suggest you consider getting a Pixel or something else already unlocked.

They are software based. I have unlocked AT&T bands on my Sprint variant, 2 actually , and they worked perfectly fine. I would show you proof but I am back on T-Mobile which the Sprint HTC 10 already has LTE support for by default.
