Thanks

One of 2 ways to SIM unlock your phone. call T-Mobile or find a site online that sells unlock codes. If the phone is still under contract you might have a hard time with T-Mobile unless you tell them your traveling and need to be able to use a different SIM.

cellunlock.net
http://www.cellunlock.net
they just did my motorola atrix only took a day to get the code, worked perfectly.
my contract was only 2 months old, service had already been disconnected for nonpayment, and i still owe at&t like $400 dollars, didnt matter.
and htc phones are on sale for only $20, my atrix was twice as much
edit-just remember the wireless bands at&t uses for data are different then for t-mobile (i forgot about that part, very expensive mistake...)

I would highly recommend using an eBay seller of unlock codes with feedback. You don't have to worry about getting screwed over because eBay covers you and plus sellers always have to worry about being left negative feedback.

Htcimeiunlock.com are very fast! I've used them with unlocking an Inspire and Sensation, took under ten mins for the code to return via email.
Cheers!

I just unlocked mine right now, last night I was on the phone with tmobile and told them "I will be leaving the country in 1 month since I am paying for the full retail price of the phone I would like to unlock it." And I wake up this morning with an email with my unlock code and instructions!!
So I inserted an att sim card and the fastest speed I saw was of about 1.5 mbps but most of the time it was like .9 so no data besides 2g edge.

I beleive the t mobile amaze has the required bands as well for At&t 850/1900 so you should be getting 4g.

To get 3g you have to mannually set up the apn.

Well I used my parents BlackBerry sim and dads iPhone sim but neither are 4g.
I later figured I had to set up the apn for att 3g but hadn't had time for that. And I and running your latest quick sense rom X.
So I'm guessing I have to have a 4g enabled sim card to get att 4g?

Can you buy these unlocked? Im still looking around to upgrade and ive been looking at a few different phones. AT&T is the best carrier in my area so id like to stick with them, but i dont like the phones they have. I know the Vivid is similar spec wise to this phone, but it doesn't look at good imo. (i dont like the square brick look)..
Why does AT&T not bring in the better looking phones :|

Yeah you can but if your gonna pay full retail price just call the carrier of the phone tell them you bought the phone itself and need to unlock it. Or by from someone on craigslist already unlocked

that's because iphone's don't support 4g and i'm not sure about bb's but i think possibly only the newest and latest ones support 4g? (not sure)
but overall they only support 3g speed on at&t.
Furthermore, there was another thread where they said if you have an at&t data plan, you need to call in and tell them to update your data plan to a 4g data plan, it's no difference in cost, but apparently there is a boost in speed. Im not sure about that one because i'm on tmobile.
I honestly think that sim cards doesn't affect data speed.
@op who has not replied lol
if you're on at&t then call tmobile. They'll ask for your customer information, tell them you're not a customer but need to be directed to someone who can unlock their tmobile phone. Since you're not a customer, they will hassle you less because they won't be asking all these needless questions why you need it unlocked and etc, but they will probably try to get you to join them. anyways most of the times the rep will be happy to help you right away. But there are a few uhhh not so happy reps who will give you **** for it. If that happens, call again and talk to another rep. You have to remember there are people on the other side of the phone, most of the time the people will be glad to help.

I just got my HTC Amaze from my employee plan and now am not working for them so they gave me the unlock code but how can I get the At&t Apn settings?

search for AT&T APN. There are countless posts for this, they are pretty much similar. If you are using custom rom such as Bulletproof it will auto detect based on your sim card.

Or look at
FAQ for the HTC Amaze 4G. Read Frequently Asked Questions before you post a question! because there is a Q & A that says
Q - I unlocked my phone and I am using it on another carrier. Where can I get the settings for the Internet/MMS?

TMO unlock code
Usually TMO is pretty good about unlock code. If you have been with them for a while, it is easy. I bought my Amaze and got the unlock code the next few days. I was travelling and it worked great.

It will always be slow since its on 2g, nothing you can do.
Why aren't there laws that make it so cell phones are all interchangeable? Something like consumer freedom so you can buy any phone you want and use it on the carrier of your choice.

Actually, T-Mobile has said they're going to start adopting AT&T's 3G bands with the hope that Apple will let them sell subsidized iPhones. So depending on where you live, you may get 3G on the Atrix. I agree though, more interoperability is needed. This GSM/CDMA split we have is ridiculous.
I'm not using T-Mobile right now, but in a year (when my contract expires) I'm switching to one of their value plans and will unlocking my Atrix to use with them if I'm still happy with it. Given that so far the only spec I see improving on newer phones is the screen resolution, I think it'll still be plenty usable when that happens.

[Q] Wind Mobile HTC Amaze no custom roms?

Got my Amaze a couple days ago and im loving it! But im reading reports on HTCdev and not having a way to install custom roms by locking the bootloader. I came from a Xperia X10 and loved custom roms i looked through some here and they look even better, but this bummed me out is there any news on this? Im reading reports of work-arounds?
There's nothing we can do about it right now. The HTC Dev only has Amaze 4G - T-Mobile in it's list. I'm worried small networks like wind and mobilicity won't bother giving us that option.. I got mine from mobilicity for $499, I would've gotten it from telus if there wasn't much price difference.. Telus has more chances of getting added to the list..
For now I'm just wondering if anyone has some knowledge on this, can we change the CID (Carrier ID) on our wind, telus or mobilicity phones so that we can trick the htc dev website into thinking that it's a T-Mobile phone? jussayin'
the only way you can do that is by changing ur phone's IMEI but nobody gonna tell you how to do it because they end up in prison.
Sent from my HTC Amaze 4G using xda premium
But what if I do it for a lilll bit of time and change it as soon as i unlock my phones bootloader and then revert it back to it's original IMEI. That shouldn't hurt anyone
the only way to change it to a tmobile cid would require having s-off so no such luck i would say sell the amaze that you have for what you can get or return it it just came out for wind and import a tmobile amaze it has penta band suport so it will do 4g on all the networks up there

Can't return it, got it in a promotion And I don't want to get into the hassle of selling and buying another again cause I sold Galaxy SII to get this phone added 100$ on top of that to get this So I'm outta of luck for now.
Do you think there's any chance there'll be a 2nd method of unlocking the bootloader in the future other than the official HTC method?
If you get the unlock code from Wind/Mobilocity and unlock it for any network you should have no problem selling it for $400+ on eBay or XDA Marketplace and being able to pick up a T-Mobile one unlocked for $420-$450.

I tried it tonight with the WIND variant of the Amaze 4G no go, like the others I cant return mine either so for the moment we are stuck hoping eventually HTCDev adds our version and mobilicity's to the list of supported devices. I have prodded them through all avenues I can think of who knows maybe if enough of us make a nuisance of ourselves they might take pity on us
One can still root the phone and install the clockworkmod and 3rd party rom.
how? isnt it just a temp root?
Amaze costs me 569 bucks because I bought it full price. That's with taxes, but yeah you could get like 450 bucks if you sell, its practically a new phone

I got my Amaze from a Telus customer for cheap. Used the HTCDev site and unlocked it without issue. Running great with Mobilicity now.
Is getting it unlocked the main issue people are having? Cause I have yet to install custom roms, but from what I can see I shouldn't have any issues?

My HTC Droid DNA abroad

Just sharing my experience with this phone as a global phone.
I nabbed myself a DNA before going to study abroad in London. The Verizon plan was hell to pay so I suspended my account -- $15 per 3 months -- and got a new SIM from giffgaff. Giffgaff gives me unlimited UK texts, unlimited 200+ kilobyte/sec internet, and 250 mins calling for 12 pounds a month. ~$18).
Setup was easy -- literally pop in the new SIM. No calling Verizon or anything. Was ready to go immediately and have had zero problems on the UK network. Reception is great everywhere except underground but hey what can you do.
Definitely recommend the phone for global use!

Good to know. While I have no travel plans in the future, being a life long Verizon subscriber I've never actually had a capable "world phone" before (I had to buy an absurdly overpriced pre-paid dumb phone last year since my TB didn't work in Spain) so it's nice to know I do now!
what type of network coverage do you get 2g 3g or 4g from them
The UK only has one LTE network right now (EE), and I doubt they're on the same bands as Vzw. So it'll be 3G.
Sent from my HTC6435LVW using Tapatalk 2
I'm actually unsure what it is. I think it's like AT&Ts fake 4g (not LTE). I've seen it say "E," "3G," and usually it says "H."
Giffgaff uses the same network as O2. Verizon's whole thing over here I believe is Vodafone

I thought the DNA didn't work internationally? Nearly got the Maxx instead of the DNA because amazon's comparison tool says the DNA doesn't work outside of the US/Canada.
Amazon is competely wrong then. It has gsm and cdma radios so it can work on any gsm network and it is already SIM unlock.

Im not really concerned with 4g per se. I'm wanting to go ATT but really feel the phone I want is the Nexus 5 based on the rumors. I like my evo 4g because of its camera. Honestly right now it is plenty fast for everything. In running meanbean on it and there doesn't appear to be anything I can't handle just fine.
I hate sprints service so I flashed the Verizon prl and after putting 5gb on it this week I should be getting terminated before too long.
ill need a service to jump on and Verizon's month to month is $70 with 2gb. That should be plenty for me. ATTs month to month sucks and I dont care for their phones right now. My goal is the Nexus 5 anyway. I'd rather just use verizons monthly with my current phone. Just depends how things work out. I also get 22% off Verizon plans so hoping that translates to a good deal.

The problem is getting Verizon's system to recognize a Sprint phone. You can take GSM phones from carrier to carrier because all you have to do is transfer the SIM card, but that doesn't work with CDMA carriers since there's no SIM card. You'd actually have to get Verizon to provision a Sprint phone for their system, and somehow I don't see them doing that.

Even if you could swap Sims it wouldn't help ya as the device itself is not provisioned to work on all of VZ freq.... Namely LTE... Lot more to how devices connect than the SIM cards...

Call verizon customer service tell them you want to open a prepaid account and port the phone and they will help you. See the only real difference between the verizon 4g phones and sprint are the lack of sim card and imei. But you can still program it to work on verizons network. All customer service agents aren't the same by the way. So if one doesn't know how to help you then another one will and you will get your phone on their. Also if you take a look in this same section this really cool guy wrote a guide on flashing a evo 4g lte to verizon prepaid.

That was my point. Sprint and Verizon are both CDMA providers and it's not as simple as just swapping out the SIM like you can do when you move from one GSM provider to another (e.g. AT&T to TMobile).

as long as you can get verizon to accept the ESN number your good. verizon has been known to be more accepting of sprint ESNs than visa versa. Though you will not get anything higher than 3g which will top out around 3-5mbps. Also you have to get the phone to accept verizon prls but i think someone has a guide for that..signal should be good though paying 70 for prepaid verizon 2gb i'd rather just get tmobile at 30$ for 5gb of AWS signal just pick up a sony xperia Z

You'll never get 3-5mbps using Verizon 3g. More like 1-2. Still way better than Sprint 3g though.

Anyway, the T-Mobile One supports every band at&t does plus AWS. Unlocked and with the right APN, it will work flawlessly on at&t - in fact the T-Mobile software has almost no lag compared to at&t.

I have an unlocked T-Mobile HTC One, and it works perfect with AT&T SIM. I can get both LTE and HSPA+. That actually makes T-Mobile version a much better buy since I'm getting ALL the bands for both carriers, much less bloatware, and WiFi calling when using T-Mobile SIM.
Couldn't be happier.

Thanks for the tip on that app. It still didn't fix the problem, but I figured out what my problem was. I was only able to get up to HSPA+ speeds since the APN settings for LTE would not work. When I put the LTE APN settings in, it would say there was a data connection issue and the settings were not correct.
After doing some additional research, I found that since the IMEI of the T-Mobile version is not in AT&T's database of LTE capable phones, my data provisioning on my account was locked in at only receiving HSPA+ speeds. My last phone was a T-Mobile HTC One S, which wasn't LTE capable, so it made no difference what the data provisioning was on my account. To make a long story short, I took my wife's HTC One X that she was not using any longer and had the AT&T phone rep put that phone on my account since it's capable of LTE and the IMEI is obviously in their catalog of devices.
After that, the settings worked immediately for my HTC One.
The more and more I look for help from AT&T, the more I realize that the company doesn't have many employees that are skilled in the way of assisting outside devices. Since T-Mobile welcomes customers to bring their AT&T devices to their network, I can only assume they would have figured this out a whole lot quicker.

Their policy on this seems to be very arbitrary. I purchased mine at Wal-Mart and paid outright for it, and then submitted the necessary info immediately to their SIM Unlock department. Here's the response I received from them a week later:

I have an unlocked T-Mobile HTC One, and it works perfect with AT&T SIM. I can get both LTE and HSPA+. That actually makes T-Mobile version a much better buy since I'm getting ALL the bands for both carriers, much less bloatware, and WiFi calling when using T-Mobile SIM.
Couldn't be happier.

How did you get it unlocked? You would have to wait 40 days to unlock it by T-Mobile. Did you find a site that can get it unlocked? I heard that most of the sites don't have the codes yet for T-Mobile version of HTC One.
