Galaxy S4 AT&T Unlock? - Galaxy S 4 Active Q&A, Help & Troubleshooting

Hello, my grandfather got a new GS4 from AT&T after he complained about his iPhone (ha). He's sick of his $85 price for only 2 gigs of data, so I was wondering if he could unlock his phone or just put a straight talk SIM card into his phone.
If someone could clarify for me, that'd be great, thanks guys in advance.
If you need any further information, just ask.

[Q] APN Settings for Galaxy Note On Straight Talk

Ok I have a moderate grasp that it is definately possible to use the Note on Straight Talk. I recently read the only other thread on it here in these forums. But I thought to start one here so that the information is available for others who need in its own post. This is also, of course for my benifit.
I am about to purchase an International Note from Amazon or Newegg this week. I plan to use it on StraightTalk wireless. I know specific APN settings are necessary for it to be usable to its full potential. So i have a couple of questions:
1) What is the correct APN settings for Straighttalk using the Note?
2)When ordering the Sim, so I chose unlocked phone or ATT compatible phone?
3)I currently have Straighttalk service on a dumbphone. Is that Sim usable in the Note? If it is, will just be able to change my plan to the Unlimited all for $45 and get the same service as I would if i ordered the unlocked or att sim?
4)I also saw some loose mention of a Data cap in the other thread but to my knowledge Straighttalk clearly says unlimited. Which is it?
Thank you in advance.
imho, the best thing to do is call your provider? anyway, for comparison, i purchased my note from company A with their own sim. Note is unlocked. im using company B's sim on my note without any problem.
SO...
Anyone using it know the exact settings and if i need to purchase new unlocked sim from them or if i can use my old sim from my original straighttalk dumbphone?
you can find the info you need here
http://forum.xda-developers.com/showthread.php?t=1487293
those are the settings most of us are using.
I didnt want straight talk to set me up on tmobile so I ordered the at&t sim..i would suggest the same if you have good at&t coverage cause you'll only get edge speeds on tmobile.
Is Sim Card in the Moto W418G same as the "AT&T Compatible Phone Sim Card" from ST??
Hello my fellow XDA-Developers,
Just have a quick question for anyone who can answer, I am coming from a Black Samsung Galaxy S2 [which I love] (on BS Sprint <--- who i HATE... no wait... who I DESPISE...) to my (sexy white) Unlocked Samsung Galaxy Note, that of which, arrives today! IM SO HAPPY ABOUT THIS!!! ;-)
My question is... is the Sim Card that comes with the Motorola W418G (www shopstraighttalk dot com/bpdirect/straighttalk/PhoneDetails.do?action=view&productVariantExtensionId=13092337) [which I had to purchase, because I really needed a phone at the moment) the same Sim Card as the "AT&T Compatible Phone Sim Card" that can be purchased separately online from StraightTalk for $14.99?? (www straighttalk dot com/ShopSims)
I would like to know this because I am planning on taking the sim that I activated with the $45 Unlimited plan yesterday, out of the Motorola W418G and putting it into the Galaxy Note that will arrive today... I am assuming/hoping that everything will function correctly (Voice, Text+MMS, & Data) once I update the APNs appropriately... This should be ok... right?? Or are they different Sim Cards??
Worst Case Senario... if they are different Sim Cards and I am forced to purchase one from StraightTalk separately... how would I go about putting my account onto that Sim Card and not the one that came with the Motorola W418G??
Thanks in advance for your help!
Best Regards,

[Q] Samsung Galaxy S4 Active SGH-i537

Hi guys,
I was wondering if anyone out there can help me? I have been trying to get this this Samsung Galaxy S4 Active Sgh-I537 to work on Verizon. It is right now with At&t. I was told by at&t that the phone is unlocked already. Actually according to at&t the S4's and up come unlocked. I keep getting the Sim Network Error. I was told by at&t that that means my sim is locked through Verizon. Anyone hear of that? I am not under contract and have not been for at least a year and this phone is not under contract either. Not sure if that is true. I paid to have this phone unlocked and the site told me they cannot generate a code for this phone and refunded me my money back. I want to get this phone working on Verizon due to the fact that I have the unlimited plan an cannot upgrade without paying high dollars for a phone. I bought this phone with the understanding that it will work with Verizon. Can anyone help me or give me suggestions on what to do? I have had this phone now for about a week and about ready to sell it on eBay if I cannot get it working. PLEASE any help would be greatly appreciated.

The i537 won't work on Verizon. Verizon is a CDMA network and this is a GSM phone. This phone will work on nearly any other network in the world except Verizon or Sprint.

Bottom line first, like the other member said, your phone is GSM based. It is IMPOSSIBLE for your GSM phone to work with Verizon because Verizon (and Sprint) use CDMA technology. (And vice versa, Verizon and Sprint phones will not work with AT&T or T-Mobile (also a GSM carrier).
Not sure HOW you bought the phone, but if someone told you that the AT&T phone would work with Verizon, they told you wrong.
You have a few options:
- You can sell the phone on eBay to someone who wants a GSM phone (if it is truly unlocked that adds value to the phone. But before advertising it as unlocked make sure it is). And use those proceeds to buy a CDMA Verizon SGS4 phone.
- You can keep the phone and switch to a GSM prepaid carrier. Straight Talk is what I use. And I am using an AT&T branded Samsung Galaxy S4 AT&T Active SGH-i537. (Because I have a Straight Talk AT&T SIM card.) With Straight Talk for $45 monthly I get unlimited talk, text, and 3GB of true 4G LTE service. That's hard to beat, IMO.
Bonus Tip: Next time, notice the difference between phones. The letters that matter are "GSM" or "CDMA." If you see a phone branded AT&T ot T-Mobile, those are GSM phones. If you see a phone branded Verizon or Sprint, those are CDMA phones. Rely on that rather than what someone tells you.
Good luck.
P.S. The carriers kind of told you right. Your phone is a GSM device, but your SIM is CDMA. The easy fix, if you are not under contract with Verizon is to get a GSM SIM, such as through Straight Talk.
If you are under contract with Verizon consider switching to Straight Talk and paying the ETF penalty. This is because the savings with Straight Talk (e.g., $70 monthly off your bill) quickly pays the ETF penalty.
Pencil out the cost of your Verizon unlimited plan. Is it worth the price you are paying, over that which you would pay with a carrier like Straight Talk? If it is, then simply get a CDMA phone. Easiest way is to get an S4 that says "Verizon" on the battery cover. :good:

It should have taken a carrier 15 seconds ito tell you in plain English that you were using the incorrect phone.
If I was an AT&T CSR I would have had you flip the phone over and tell me what it says or what graphic it had on the battery cover. I believe Verizon phones say "VERIZON"
On hearing that I would have then tried to sell you an AT&T account.
Whoever sold you the phone (eBay purchase) and the carriers left you floundering on the dock like a fish out of water.

[Q] Help with nexus 6 (several questions) (tmobile to Verizon)

After attempting to buy from 3 retail tmobile stores (who wouldn't sell me the phone without a plan) I ordered my nexus 6 via the phone. Several retail workers and customer support agents on the phone have told me I need to keep service on my phone for 45days to get the unlock code from them. Currently awaiting delivery (back ordered )
What happens if I don't wait for the unlock code And I just insert my Verizon sim?
The tmobile nexus 6 is suppousedly the same as the Unlocked GP nexus 6, so what exactly is unlocked?
I'm coming from a note 4 (my note 4 lags a lot more than everyone else and I can't take it anymore, couldn't figure out the cause)
will the nexus 6 have multi windows at all?
Also how do you use the notifications on this (I played with a 2013 moto x, is it the same?)
Sorry for all the question and thanks in advance for any help.
I just bought the phone from T-Mobile with their cheapest plan Wednesday and I'm canceling them today. From what I've been Reading I shouldn't have to pay anything for the plan. I haven't used it at all and just popped my Verizon Sim card right away.

nothing, except youll have a code that does absolutely nothing. i bought my n6, n5, and n4 via tmobile. they have never ever sim locked a nexus, never. its exactly the same n6 that you can buy at the play store.

Thank you, you pretty much saved me 45 days of phone bill payment.
Im assuming if i dont activate the tmobile sim, i can cancel/not have any charges.
I prev had the z1s with them for like a month and canceled due to their poor customer service , surprised they let me sign up again. (Then again theyre the ones who wanted me to sign up, i just wanted to buy the phone outright and use it on my unlimted data verizon line)
T-Mo Nexus 6 on VZW
OK, so I see that the T-Mo Nexus 6 works fine on VZW, however I see that all of you said you bought it outright, how about buying subsidized? Will it work if on VZW then, since the phone is getting activated, will it lock it to work only on T-Mo? Thanks for the help in advanced!

As stated above T-Mobile doesn't sim lock phones.... They also don't subsidize phones because they are the "uncarrier" so it will work if you pop the Verizon sim in assuming you have a bank sim ready to go.
As what others have said, T-Mobile doesn't lock the phones.
AT&T and Sprint are on a different story, AT&T I've heard locked their phones via carrier.
Sprint doesn't lock their phones but some people have reported buying them from Amazon have carrier locked so be careful on that.
T-Mobile will however make you stay with them for one month (I believe) before you can cancel. If you cancel, your EIP balance is due. If you pay outright, you'll still have to stick with them for a month. At least thats my understanding of it.
U.S. Cellular also sells the phone now but I'm not sure about their policy.
I just bought a white 64gb off swappa, anything in particular to check for? (My tmobile one is backordered).
Pretty sure i overpayed, but as long as the phone is like new i'll be happy.

Check the imei of course to see if it has been reported stolen etc or if the user has paid off the financing if it is financed.

Swappa pre-checked it, ill check it the imei again when i receive the phone
Its a 64gb CW with an extra turbo charger, dBrand skin, and a qi wireless charger. And it has the one year manufacture warranty.
http://swappa.s3.amazonaws.com/listings/GCM288/images/HwOwxHlg_small.jpg
I (over)paid $910 ($900 + $10 swappa charge) and its my first swappa purchase so hope all goes well.
Double checked my tmobile order and its not arriving till 1/19/15-2/2/15. And i havent seen any avail 64gb on moto or the GP store

Wow.... I would have definitely waited a bit longer than pay that much for a phone.
Theres availability, you just need to stick around for them. Have a auto refresh script that alerts you when its available. They randomly add them in stock.

Glad I caught this thread. Few questions to get clarification:
Assuming I buy the N6 from T-Mobile (subsidized or not) - what is their cancellation policy? Someone mentioned 45 day scenario where you can cancel without penalty? Is that true?
Thanks!

They dont do contracts. Just dont activate their sim and call them up saying you want to cancel.
If youre looking for a 32g id recomend buying off motorola.

Reliable and inexpensive way to unlock phone

I was wondering if anyone sim unlocked their ATT Galaxy S6 for a decent price? I bought the phone at full retail price, but At&t keep telling me i need 6 months of gophone service to unlock it, which i think is BS. I would be grateful for PMs or replay to this thread, thanks.

Still No Way to Put Stock TMO ROM on ATT S6, Right?

I'm ashamed to even ask.....
Former TMO S3 owner here who switched to Nexus and never looked back. Things are just so much easier now with firmware updates and rooting.
We currently pay cell bills for one of our workers and his wife on our TMO family account. His wife was using my old S3, and without talking to me first, he bought her a SIM locked ATT S6 online recently.
I'm working on a SIM unlock code, that won't be a problem.
I'm right in thinking that there's no (current) way to load a TMO S6 ROM onto the ATT S6, right?
Bootloader still locked up tight on ATT?
I know that in the past some of the Galaxy S phones had hardware differences......are the ATT and TMO S6 variants now the exact same hardware (other than exterior logos)?
Sorry for what seems to be an obvious and already asked question. I know someone asked the same question back in August.....wondering if anything has changed since then.
Thanks for all replies.
Yup, bootloader locked tight, can't even get a root working besides the people who are selling it
