Using a different carrier sim without unlocking - HTC Amaze 4G

Has anyone tried to use a different carriers sim in the amaze without unlocking it?
I came to Mexico for vacation and bought a phone here to use while I was here..
I didn't unlock my amaze to work with differents sim cards so I thought it wouldn't work.. well one day I got curious and switched out the t-mobile sim for a telcel ( name of the cell company in Mexico ).
Waited for it to boot and to my surprise it works, it has 4g and all.
I was wondering if this has happened to anyone else?..
The phone is S-off btw..

I just bought one today, it's supposed to be unlocked, tried my tmobile sim but nothing,the Mobile Network box is greyed out, what to do?

Did you s-off your device it did you buy UT lie that? If you bought it lie that chances are it was unlocked by that person. If not you at 1 in a million

I'm the one and only owner, I s-off the phone myself, but never unlocked it due to that I don't travel much outside of the U.S.
Yea sms and mms work... Plus 4g speeds here are crazy fast...

Little question
I have an HTC amaze from T-mobile and put in a telcel sim card, i can make and receive calls but i still dont have any luck with the data, APN's already set up and nothing, are you sure that you didnt unlock and only are S-Off?

If you're unbranded, your unlocked! If you're T-mobile branded, you weren't supposed to be unlocked, unless the precious person unloxked it for you.

Meaning you want to unlock your sim card right?
I don't know why you would buy to phones >.<
but maybe you should just try
taking out the sim card and putting in the revolution. I mean its the same carrier. I don't see why It wont work. Unless the sim cards is registered to your phone then maybe it won't work. But who knows
Okay 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.

or flash quiksense automaticly detects it on install
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

hua? you mean buy it From the carrier then have them unlock it?
I think you can do that but that's too much money. Your better off on craigslist and have it unlocked online.

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.

[Q] Switching between LTE phones

If I wanted to switch from one verizon 4G phone to another, do I have to call and switch the ESN/IMEI or will just swapping sim cards be enough?

Just swap SIMs.
Ive been wondering this. Lets say my phone gets stolen, can I still call verizon and have them lock the phone as stolen or can someone just stick their sim card in and works?

you can get the phone blacklisted.

Sweet. That's what I was worried about.
Sent from my ADR6425LVW using xda premium
it would get black listed but they would have no trouble sticking any GSM network sim in it.

I don't think verizon has fully transitioned over to black list imei numbers to fully block them from being used on the network.

Carrier name issues on T-Mobile

Hey guys,
I'm kind of new to android stuff, so bear with me .
About a week back I bought this Motorola Photon 4g for Sprint off craigslist and used the kddi radii trick to make it work on GSM networks, namely T-Mobile. Right now imeon the hybrid 2.3.5 rom, but even when I was in the stock sprint rom, the carrier name randomly shows up as T-Mobil instead of T-Mobile. Is there any way to fix this other than spoofing the carrier name? Thanks for the help!
From what I know, the name is stored in SIM card, try to replace it with carrier.
Thanks, I'll try that. I'm actually planning on doing that soon anyway . The strange thing is it sometimes shows the full name T-Mobile, I'm still trying to figure that out haha

Where is the trick?
Sent from my MB855 using xda premium
My phone does this too, I'm not sure why. To me it seems like it says 'T-Mobil' when signal is pretty weak, but i have overall weak signal in my apartment so it could just be me making a bad guess.
same thing
i also have the same thing, but i haven't noticed it till you have mention it.
i guess it belongs to 2G/3G. coz when you are having connected to 2G it tells you T-mobil
while when you are connected to 3G it tells you T-mobile.
pleas tell me if i'm right
Can you not get tmobiles 4g or is it because bootloader is unlocked?

Tmobiles 4g is HSPA+ which is technically 3g
Jellybean Poppin MoPho
You guys must be in the refarm area cause the 3g frequencies are the same as the iPhone's. I'm still waiting on that . Btw I got a new SIM and it hasn't said T-mobil yet so maybe it's just a certain kind of sim that does it?

Carrier unlock

Is there a way to carrier unlock the amaze without calling T-Mobile?
I called T-Mobile and they gave me the code but I put it in wrong and after one failed attempt you can't put it again.
What's weird though is that I went to mexico and inserted a foreign sim card and to my surprise my phone got service.

Hey Eduardo!
Well the best way (easiest) to unlock is to just call T-mobile and say that you're going to some foreign place like Brazil or Ecuador or something. If one rep refuses to unlock you just call again and repeat until someone gives you an unlock code lol. Just tell them you're going out of state and need an unlock code, they will give it to you 9/10 times anyway, so you shouldn't have much trouble.
The OTHER way is to do this. Right now it's in a gray area because of the stupid law banning unlocking (except by carrier), but the Amaze was released before the law came into play so I guess it avoids the law. Good luck!

Also, if you entered the code wrong, it's fine! It will still work anyway. :good:

I'm going to update ALL of them now and put them in line with SS3.2. Time for full domination again lol.
I'm also working on a Sense 4 port and MIUI but it's harder.
But yeah good luck, I unlocked my S3 within the dialer. HTC can't be too hard either. :thumbup:
