[Q] Is the Droid 3 unlockable (SIM carrier) for AT&T or T-Mobile USA?

The Droid 2 Global and Droid Pro had a SIM card slot but can't be unlocked for US carriers. Is the Droid 3 any different?

Nope. It's the same on the Droid 3.

That's complete BS. I was ready to buy the D2G outright (not a Verizon customer), but didn't because of this prime example of Verizon continued lock down of their devices.

Much like AT&T and T-Mobile locking their devices as well? Sure you can unlock the phones but you have to be a customer for X amount of months, and that's the same with Verizon. Much like how AT&T for a while didn't like anyone side loading applications on their Android devices? Much like AT&T not allowing their iPhones to be unlocked?
Sorry man before you make any one carrier/manufacturer look like the "bad guy" you should make sure others are not doing it.

Yah but on a att or tmobile phone you can simply buy the code and voila you are good to go. You unlock a vzw phone and you still cant use it since they put custom software that specifically blocks u from using it in the U.S. so when you unlock it its still not really unlocked. Its a douche move.

Reread what I said, and think harder about what I said. Regardless if you can pay or not. It's still locked from the moment you purchased it. You have to wait Months to get an unlock code or pay someone to unlock it for you. Just because Verizon locks you out from using it from other carriers there are way to adjust it. You could always purchase a milestone which is the same thing right?

Actually, most unlocked AT&T and T-Mobile smartphones won't work on 3G on the other's network. Different bands. Same sort of attempt at locking the phone from being used with other domestic carriers just like Verizon. When the companies pay for an exclusive within the country, they want to do their best to protect their investment and keep it exclusive.

This also applies for GSM carriers outside of the US? I live in Barbados and we use 1800 I believe, was looking at picking up a D3 unlocked once the bootloader lock had been circumvented.

Actually I was referring to the carrier lock that needed to be removed for US bands.

according to the wikipedia entry it does not support 1800Mhz bands =\ If I'm not mistaken, that's the same as Tmobile in America for UMTS 3G bands

DROID 3 - Will my phone work using other GSM SIM such as AT&T or T-Mobile in the United States?
Will the Droid 3 work using other GSM SIM such as AT&T or T-Mobile in the United States?
Your phone is designed to be utilized with the pre-installed SIM card. You will need to enable international roaming AND activate your pre-installed SIM card in your phone when traveling outside of the U.S.
The GSM and UMTS bands that are supported in Droid3 Global will not work in the United States. The GSM and UMTS bands are only able to be utilized outside the U.S. A GSM SIM card such as AT&T or T-Mobile will not operate in the U.S.
Contact Verizon Wireless for more information dial *611 from your cell phone or call Verizon Wireless @ 800-922-0204.
Note: GSM and UMTS-based global services work only with SIM card supplied by Verizon Wireless® or by another non U.S GSM or UMTS service provider. When you set your phone to use a GSM 900/1800 or UMTS 2100 network, you may be prompted to enter a subsidy code. To get this code, contact Verizon Wireless.

If I buy the phone from the Motorola store, will it be unlocked for use with International SIMs?

Regardless of where you buy your phone it will be locked to Verizon. Verizon will provide an unlock code to customers based on certain prerequisites. This code will allow you to use another carrier's sim cards while outside of the US, but you can not use any US based GSM providers.

If it has the Droid 3 name (which means it's the Verizon version of the phone), the SIM slot will be locked regardless of where you buy it. Some versions released in other countries (like the XT860 4G in Canada) may or may not be SIM locked. That remains to be seen.

But all those restrictions are software based, yeah?
According to GSM Arena, the Droid 3's hardware supports HSDPA on 3 of the four 3G frequencies, including the two that I think AT&T uses (850/1900), and one that I think T-Mobile uses (2100), and it supports 2G GSM on all four frequencies.
If the bootloader ever gets unlocked and we get custom roms, will that potentially remove the carrier restrictions for GSM networks??

Potentially.
The only other way is to have the required files from Motorola to unlock the bands, which aren't publicly available. Team Black Hat evidently has what's needed to do that for the Droid 2 Global and the Droid Pro, but you have to send your phone into them along with $100 to get it done. Maybe there will be an option like that in the future for the Droid 3.

I seriously hope so. I messed about with the Droid 3 at the Verizon store and I really liked it. I'd love to be able to use it (or Bell's version) on T-Mobile.

Yes, a non-Verizon rom can solve the problem. A lot of Chinese user bought Droid 3 from ebay and flash it to China-Telecom rom (major carrier in China) and get all bands unlocked, no GSM unlock code needed in that case.

But what about unlocking the US based GSM carriers?
And what about the aosp roms?
Is the restriction in the rom, or in the radio file?
There's a CyanogenMod 7 alpha version being developed, and people are reporting that something in its build.prop gives them better gsm reception overseas. Would it also allow a US Droid 3 user to use a US GSM carrier, such as AT&T?

Verizon Variant

Will Verizon Variant need specific roms or will these cross over easily? Just wondering if The Verizon version will be developed seperately like sprint or like att/tmo

Since the Sprint variant is behind by a bit, the Verizon one will probably have separate ROMs since it is CDMA.
-Sent from Marino's One-

If we are lucky it will be the same as the Sprint version. I would not expect the GSM roms to be compatible.

Knowing Verizon, it might have an encrypted bootloader, which means no roms at all until someone cracks it.

[Q] Some Questions About Different Moto X Models

Hey all,
I'm looking at purchasing a Moto X (possibly two, if my wife replaces her iPhone...). I'm currently not tied to any particular carrier, but I'd like to keep my options as open as possible. I'm going to buy the phone/s at full price, and then bring them to whatever carrier/service/MVNO I end up with.
From what I understand so far, there are two basic models of the Moto X -- one for Verizon (CDMA), and one for GSM-based networks.
Here's my basic question: What's the difference between these phones??
The Verizon website lists the Moto X as a 'global' phone, which implies that it has a GSM radio in it, right?
If so, does that imply that the 'Tmobile' (or otherwise GSM-based) Moto X has a CDMA radio?
Then, as if I'm not confused enough, I find the 'Developer' edition of the Moto X... in two versions -- one for Verizon, and the other for 'GSM'. The developer edition provides an unlockable bootloader... cool, I'm a fan of that! But!! Isn't the Moto X part of the Motorola Bootloader Unlock program? It is (hxxps://motorola-global-portal.custhelp.com/app/answers/detail/a_id/87215)... so what's the difference between the 'Developer' edition, and the regular edition?
I'm sorry if these are silly questions -- but I've spent at least an hour Googling today, and didn't find any answers that I found conclusive. Thanks for any help you can give!!

Unless you absolutely have to have VZW for the service - do not buy the VZW model. I am on VZW and have the Dev Edition from them. VZW is always the last to get updates.
So there is just a lot going on with this phone...
There are two different Developer Editions. GSM (for AT&T and T-mobile?). I know it is for ATT and believe it is also for T-mobile. But the T-mobile Consumer Edition also has an unlockable bootloader without buying the developer edition?
Even though the MotoX is listed on Motorola's Bootloader unlock program - it is only certain models. Sprint, T-mobile, US Cellular. Verizon's is only the Developer Edition. ATT would only be the GSM Developer Edition.
My recommendation is T-mobile if you get good service from them. They are going to get updates first.
Also as far as CDMA Vs. GSM; Verizon and Sprint use CDMA technology and ATT and Tmobile and most others use GSM technology.
I know that sounded like a big mess - sorry. I am tired and its all I got for now.

The CDMA version has gsm capabilities, but the gsm version will not work on CDMA.
If I were in your position, I'd get the gsm developer edition or the T-Mobile version. Either of those should be compatible with most carriers unless you absolutely need a Verizon phone. If so get the VZW developer edition.

That would be my choice, as well. However, I'm not 100% sure I want to commit to T-Mobile, yet... their coverage seems to be the most lacking of non-Verizon carriers. I was actually thinking of activating the phone on Ting (a Spring MVNO) to begin with.

So what you're saying is that the VZW Dev edition would theoretically work on other CDMA carriers (i.e. Sprint/Sprint-based networks), and also GSM-based networks (i.e. T-Mobile), right? But that the T-Mobile version with only work on GSM carriers (i.e. not Verizon, and not Sprint)?
As much as I'd love to just commit to T-Mobile's GSM network... their coverage maps have me hesitant, heh.

With T-Mobile you don't commit, other than the cost of the phone which can be resold. They don't do contracts so you can easily switch to another carrier if needed. I've been on Verizon since their inception and I now have à T-Mobile "test" line which is working pretty well. As mentioned above, it's probably best to get the GSM dev edition since it can be used on AT&T too.

I'm nearly certain the T-Mobile version works 100% on AT&T HSPA & LTE.
I ordered one last night, so I will clear that up when it arrives next week, but I'm pretty certain I've already seen others reporting that T-Mobile works fully on AT&T and is unlocked out of the box.

Gotcha. Ideally, though, I'd like a phone that would work on CDMA AND/OR GSM networks... would the VZW and/or VZW Dev Edition be capable of that? That is, could I activate on a Sprint-based CDMA network like Ting, and then switch to a GSM-based network like T-Mobile later, if I wanted?

Awesome! Looking foward to what you find out.

I think you need a Sprint version to be able to use Ting. Last I heard, they don't flash Verizon phones to their network. I'm not sure if the Sprint version can be unlocked to be used on T-Mobile if you change your mind later. I'd highly advise just picking your carrier first before picking your phone.

Was starting to think that myself, heh. Just kind of a bummer, because I know I want the phone -- but I don't know which carrier will end up fitting me best.

HTC One Dev Edition radios?

Hi all, is there any difference between the radios on the Dev edition vs. the normal one? For instance, if I have the Dev edition, what's stopping me from flashing an AT&T, T-Mobile, or Sprint ROM? Shouldn't they all be compatible with my device? Does flashing any of those affect my radios?

The Developer Edition radio is set up for GSM service by default. I know there's a setting to change it to CDMA, but I have yet to see somebody post on trying it with their Sprint or Verizon HTC One. If you're on AT&T or T-Mobile, it works. If on Sprint or Verizon (or other CDMA provider), maybe. I would be curious since my friend has a One with Verizon. It pains me to see all that bloatware on his phone that can't be removed or disabled.
Short answer to your question. Nothing is stopping you from flashing an AT&T, T-Mobile, or Sprint ROM. But I fail to see why somebody would want to do that if they have the Dev Edition. Unless they really like bloatware and carrier restrictions.

[Q] Modifying a SPRINT HTC ONE to act like an international one?

Well I have been told that my Sprint version of my HTC ONE M7 wont ever be able to act like and international version, well why cant it ?
If its a partition problem cant we just modify it? just like sdmerge400 modified the partitions of LG e400s ????
I would like if someone would make a mod for this stuff (As my phone is unlocked and i have been told that GSM is now enabled. Source: Sprint Rep.)
And a fact is that both have the exact same RF chip the difference being that sprint has locked down its phons to CDMA only , Which is unlocked by carrier unlocking (That I have already done )
So i think it must be possible!
(PSardon me, I have made posts like this before but this one is a little bit different.)

Um.... Not entirely sure that's right. You'll want to double check the frequencies for the Sprint M7. Any CDMA band frequencies cannot be used for GSM or LTE purposes.
At least, that is what I was told.
Unlocking your phone will allow you to use the built in GSM functions of your M7, but the CDMA frequencies will remain inaccessible. My $0.02? See if someone wants to trade their international One for a Sprint One (lmao good luck), or sell it and buy an international One.

Sprint M7 cannot be converted to International M7.
Modem chipset is different. Firmware is different.
GSM unlock on sprint m7 is meant only for out of US gsm carrier Some people had success in using it on US based gsm carriers
Max you can do is modify xml files so your phone shows network options like in GSM models.
