Unlock sim Att HOX

I'm new so stick with me, I want to unlock
My One X to work on straight talk but here's the problem, bought on att but I no longer have service and my att account is in bad standing. They canceled my account for me. So does that mean that even if I unlock the phone it won't work or will it? I want to know before I pay for the micro sim.

Its been reported by several folks on here that the phone does not need to be SIM unlocked to work on Straight Talk, as long as you pick the AT&T SIM when you sign up.

Straight Talk uses the same towers as At&T, so the At&T SIM will definately work.

Straight talk with One S and changing apns

Sent from my SGS3

So I bought my son straight talk pre paid plan for his tmobile one s. Where we live straight talk uses T-Mobile as a carrier. Right now he is visiting his mom for xmass and the area he is in has straight talk but through at&t. Can I change the apn settings to make his tmobile straight talk work on at&t straight talk? I did try to change his apn settings to at&t straight talk and the apn wouldn't stick. He's running Zen Rom. Also I never updated the hboot. It's still below v .13 (that iterations not right but I think u guys well know what I mean.) Thanks for the help!

Hard to say. I also have ST but I unlocked my phone and am using the micro at&t sim card. I'm not sure exactly how it works buy considering there's a at&t and TMO sim card. I think it works with the network the sim card is associated with. I could be 100% wrong but I may also be right.

Thanks for the reply. I'm going to give ST customer service a call. How lame though tmobile ST doesn't work on at&t ST. I asked at the store where I bought the SIM card and they said that they only sell ST through Tmobile in the twin cities... oh well maybe I can get it online or just change to another at&t prepaid.

Hopefully CS will give you some good info. They are never too helpful when i call in.. Not sure if it'll work but maybe order an at&t sim and just switch out which ever sim with the better coverage is.

Hi everyone!
I just got on to ST with a t-mobile htc one s and am using the APN given on the sheet that came with the sim card. My emails are coming in just fine but when I go to send or attempt to download a picture text, it fails. Can anyone tell me what they have used for their APN? I was also curious if maybe the locked tmobile APN's are having something to do with the fail. Anyone know how to get rid of them so I can create a separate MMS APN?
THANKS!

What Rom are you on? If stock Sense what version? Also are you using the TMO ST SIM card or are you unlocked and using AT&T?

Just noticed actually that the ST APN isn't sticking. It keeps going back to the locked TMO APN. The version of Android I'm on is 4.0.4. I just tried to use the app APN Lock, but it states that Android versions 4.0+ don't allow it to work. I'm using the TMO ST SIM card.

I'd definitely recommend you unlock your bootloader(if you haven't done so already) flash recovery and install a custom Sense Rom or maybe even give a AOSP Rom a try. I personally just installed LiquidSmooth Rc1.5(AOSP) And when I booted up the ST apn was already there and selected..
All the necessary tutorials and roms are located in the Development Section.
This all assuming you haven't unlocked/rooted your one s before

HTC one x ATT on Straight Talk question

Im about to buy a new ATT branded HTC one x USA.
I was wondering do i have to buy a unlocked version if i am wanting to put on Straight talk with there ATT Sim card from there site?
I hear mixed opinions / answers.
Do i have to have a unlocked to use on straight talk even though it uses ATT towers and i here other posts not mentioning unlocking / unlocked phones?

I am using a art HTC one xl right now on straight talk
If you order the att SIM card from straight talks website it will work on any att phone it doesn't have to be unlocked my HTC one xl is not unlocked an runs great on straight talk with the micro att SIM straight talk offers I get the same speeds as att also
So simply no if you have the att SIM from straight talk any att phone will work it does not have to be unlocked

Do you get a new number when you activated straight talk?
I have no service / phone in front of me. But i hear you have to port your current service number what if you don't have one? Do they give you a new number like ATT Gophone plan i just activated and choose my number on there website.

I don't really understand what your asking if you can or if you have to port a number not sure if that's it or not so let me answer them both
You can port your existing cell phone number to straight talk
You do not have to poet your number like me I didn't have a number before straight talk just you choose activate an get a new number or something along those lines an they will give you a phone number for your area
Sorry if I still didn't answer everthing for you buddy

Krazy....I have a HTC One X and a ST micro sim that I have been using for the last 6 months in an iphone. I want to use the sim in the HTC but for the life of me I cannot get the data connection to work. Both phones are At&t versions. I get voice and texts, just no data. Can you help? Maybe share your APN settings?

[Q] Verizon Samsung Galaxy SIII - SCH i535 - GSM doesnt work

Folks, I need all of your help.
I have bought three Verizon Samsung Galaxy S3 phones in the US. This was purchased via the corporate program. I was told this is a global phone and I cannot use GSM SIM cards if I am in India.
Verizon also told me the phone would be global only after the 4.1.2 Jelly Bean update. The phone is upgraded with the newest verzion of 4.1.2.
Now, the phones are in India. I insert the local GSM Sim (Airtel / Vodafone) and cannot seem to be make it work.
1. With Airtel SIM, I played around with the Global Network Mode and GSM and CDMA etc.. I seem to get Airtel listed as a network and when I select it, it says "unable to connect, try later". The same happens whatever I do.
1. With Vodafone SIM, I inserted the SIM, turned on, set it to Global and it picks up the network in a jiffy BUT when I make a call it says Mobile Network not available or when someone calls to this number says it's switched off, but the tower comes up and says Vodafone IN at the top but nothing happens.
I then searched XDA, I found solutions for the APN settings etc.. and the Phone Info tool to change it to Global etc.. but nothing seems to be working. I also rooted the phone, put on a Synergy ROM and still the same problem.
I called Verizon Global Support and they do their usual blah blah and says that if their SIM works and since there is no other complaint they cannot do anything about it. Local carrier support in India have no clue at all.
I have seen in the forum that some say it works in India with an Airtel SIM too but why not me. Just in case I bought a new replacement SIM from Airtel 64k and that doesnt work too.
I need urgent help since I have bought three phones and all three of them doesnt work.

Thanks for your post. I did try the steps in the link but no go. It's soooo frustrating. I get to the point to select my networks, but when I select, it says "unable to connect, try later". Could it be GSM Band problems?. I even get Airtel for a sec and then it says emergency calls only.

Hey I have the same problem. I have a Verizon Samsung SIII and I can't seem to get the data working. Voice calls work just fine. But I spent hours getting data to work, but no luck. The problem seems to the lack of APNs when you look for one. I think Verizon has locked the device in a way, even on 4.1.2, that you can only use their SIM card to "see" an APN. I'm getting furious with Verizon locking the devices.
Please let me know if you figure out a way. I'm in India for a funeral and for a very short amount of time. I need the data working so that I can stream the ceremony back home. Vzw is a sack of duesch for pulling such moves. Grrrrrrr!!!!

3. Backed up the apn settings to sd card using apn manager pro.
4. I had normal sim, went to idea showroom and got new microsim.
5. Installed apn manager pro on s3. Converted to system app using titanium backup. With the sd card having backed up working apn, restored the apn settings using apn manager pro.

Unlock note 8 does not support LTE on AT&T

Hello,
Can you guys who have the unlock note 8 and on AT&T network confirm that it does not support LTE?
I saw a review on Best Buy stating that he could not get it to work after numerous call to tech, and AT&T suggested they buy the AT&T version and unlock it.
I just bought the unlock version from Samsung and planning on using it on AT&T, I tether a lot in my car and if LTE is not available I will probably return it.
I am not going to paid almost $1000 for a phone that does not support 4G LTE

Exactly. Weird how it's not working. I had an unlocked version of the S8+ on AT&T which worked on the LTE+ network.

I have the factory unlocked version and I have LTE. Make sure when you activate your note they use and new sim.

Well, I am in the same boat as you. I bought unlocked directly from Samsung and put my AT&T sim from my AT&T branded S7 edge in thinking that it will just work. First I didn't even have data so I changed the APN and got data but only H+ speed at best. I did chat online at AT&T and the first time the tech said that I needed a new sim and I can get a free one at a local AT&T store. I reverted the phone back to stock without data connection and went to my local AT&T store. I told the guy there what the tech said and he took my phone and just mucked around with it and got data connection but only H+. He said it is probably the best this phone can do. I am like ??? But I didn't argue with him and left. I again went on chat at AT&T website and the tech did something on her end and eventually open a case for me. I waited 2 days and finally got an email saying that it is the area that I am in and that would be the best signal I will get. Again what the ????. I had LTE all along in the past at the same place, home. So after 2 more days, I again did chat with AT&T and this tech basically said I needed a new sim and he will send one to me for free. So now I am waiting for the new sim and hopefully with the new sim, I can register the sim with my IMEI and get LTE back. You should probably save all this trouble and ask for a new sim to start with. Good luck.

Thanks Xenshen, I think that will be my last resort. You said unlocked verizon variant, what is that? There is unlocked and there is branded unlocked directly from Samsung. My is not even branded. I guess either way works with flashing. Would love to get the direction if you don't mind. I will save it for the last resort after I try a new sim.

all Verizon phones are unlocked without the bootloader being able to be unlocked but if your flashing carrier firmware you can go from any carrier without voiding warranties and messing your phone up. The unlocked one from samsung just comes without the bloatware and from what ive read its still bootloader locked as well because of the snapdragon chipset in it. But if you put the att rom on it you wont have a issue and will get all the features including the lte enhanced services and all
---------- Post added at 11:49 PM ---------- Previous post was at 11:47 PM ----------
ive flashed 3 different roms on it now so seems to be just like the s8 where all US models are the same minus the carrier oh and i removed most the bloat and just disbaled the apps i wont use

Well all I had to do is put in the sim from my V20, add the NXTGENPHONE APN and it was game on immediately.

i got the unlocked verizon variant and switched to att and i kept getting h+ i then flashed XAA rom same thing if you want to get all the features and the actualy 4g + like i have now you need to flash the rom wont void warranty and legit i can send you directions how if you want took me a day and a half of searching and trials
Thanks Xenshen, I think that will be my last resort. You said unlocked verizon variant, what is that? There is unlocked and there is branded unlocked directly from Samsung. My is not even branded. I guess either way works with flashing. Would love to get the direction if you don't mind. I will save it for the last resort after I try a new sim.

The new sim will fix your problem. The old sim was connected to other phone imei.

I had the same issue
I received my phone last week and I was also having LTE problem. At first it was no service, then after some apn configs I was getting H, and H+ speeds. I had talked to multiple ATT reps and most said I would have to wait until they released the phone for it to be seem in there system. Since it was realeased on the 15th and the update came today, I thought it would fix it. It did not so I called ATT again. after about forty mins on the phone and many restarts later we finally got it to work. I now have LTE and LTE+ for ATT on my unlocked SM-n950u1 .

I think he said something along the lines of, " It's permissions were defaulting to 3g," or something similar. He may have also removed my device and re added it. He also mentioned that he was getting permission from a supervisor to make an official report since it seems to not be an isolated incident.

Attached is the post on best buy I was referring to, that's why I was scared since I have already ordered it.
But glad to hear it works and should work just like the locked version for LTE.

Getting the unlocked today, will goto local AT&T store and get a new sim card first thing. I will let you know how it goes.
