AT&T sim in Tmo tab - Galaxy Tab Q&A, Help & Troubleshooting

I just got a message on my tab that I need a data plan for my tab. I never had this problem with the first tab I had that I sold. Bought another tmo tab of Craigslist unlocked it now I got the message a few hours later. I didn't think att could detect that.

[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,

Bought a AT&T Note 3, can i not activate it?

So basically my roomie was kind enough to let me use his discount to buy a note 3 since i'm not eligible for a while.
Obviously the phone is for me, even though we bought it thru his account.
So do I still need to call AT&T and activate the phone (it came with a sim card in the package)
Or i can just ignore the sim card and calling them and just use the new note 3 with my sim card, and he uses his iphone with his old sim card thats already in there.
Do you know how does the whole thing work?

If you already have your own SIM card linked to your account, just put it in the phone and you are good to go as long as the phone is an ATT model. Also the phone will only work with a MicroSIM regular sized SIMs will not fit this phone.
On ATT the phone has no bearing on your account. What you are paying for is the SIM. I bought a Lumia when my contract renewed with ATT. Could not stand it so I bought an N3 full price and slapped my card in it. The device is even updated on my account on the website as being a N3 and not a Lumia.
oh cool.
So i dont have to do anything?
ATT doesnt care that the phone was never activvated?

On ATT phones are not activated. They are ready to use out of the box. The SIM is the key. All your account data is linked to the SIM, not the phone. You can use any phone that ATT sells on your account and you don't have to buy it from ATT . I bought my N3 on Amazon at full price but I still use it on my Lumia account. The exception is if you use a smartphone on a none smartphone account, when they see it on the network they will upgrade you and charge you accordingly. You cannot use ATT with a smartphone on a standard phone account.
OK let me shed some light. If you call and give them the imel number of the new phone then its registered and if you have the insurance it will automatically be transferred to the new phone regardless where you got it. That's the benefit. I have my Lumia insurance with att and my note 3 and s4 with square trade.

[Q] Galaxy S5 still connecting to service although blacklisted days ago

I have a blacklisted S5 and I popped in a AT&T GoPhone sim and its still connecting to the service. I get LTE text and voice. So I'm just wondering whats going on. Would you guys recommend unlocking it and using it with T-Mobile? I also checked the IMEI with T-Mobile's website and it said its blacklisted. AT&T said the same but is still working. Thanks for any answers.

Blacklisted phones will work for a day or two before getting disconnected. Whatever check AT&T does, it does not happened right away when you insert the SIM it takes sometime. But it will get disconnected.
Thanks for the heads up. I decided to just go ahead and list on eBay as a blacklisted phone.

[FYI] UNLOCKED S6A sent for repair and returned LOCKED

Hi guys,
I just thought I should share my experience with SAMSUNG and AT&T.
I've bought my brand new UNLOCKED S6 Active from EBAY about 13 months ago and used it for 11 months with no problems at all. I've never dropped it nor put it under water or anything etc. However about 2 months ago the phone started freezing and randomly rebooting.
I'm an IT specialist so after carefully examining the phone during freeze I realized it's probably a defective motherboard. The phone was under warranty so I shipped it to SAMSUNG USA for repair. They send it back after two weeks with a replaced battery claiming the phone is fixed. Of course it wasn't and I had the exact same issues as before. I had to send it back to SAMSUNG and after another month they confirmed it's the motherboard and replaced it. The service slip states "Replaced PBA".
Since then the issues are resolved but.... as soon as I've put my international SIM card the phone stated "Invalid SIM card. Enter network unlock code". What a surprise! I called SAMSUNG and they claimed it's locked by AT&T (??) and connected me to AT&T rep about it. I've explained everything again and the AT&T guy said since I don't have an AT&T account he'll send me the unlock code after 3 business days to my phone. "How exactly are you going do to do that when my phone is with an international SIM card which is not working on the locked phone?" I asked. "Oh... in that case I'll give you the code now". So in a minute I had the code and the phone is UNLOCKED again.
Cheers!
Hey I am having the same issue with S6 edge. I bought AT&T S6 edge unlocked from ebay. I used it with Tmobile sim. Something went wrong with the phone, sent the phone to repair and Samsung replaced the PBA and sent back. Now it is locked. When I put Tmobile sim, I get this "Invalid SIM card. Enter network unlock code". I called Samsung and they told me to call Tmobile to get unlock code. I don't think it is going to work. How did you get the Samsung to connect AT&T rep to you?

The SAMSUNG rep told me to call AT&T and request an unlock code. I told him I'm living in Europe and I've never had an AT&T accout which is required in order to speak with AT&T support. So he was kind enough to call them and then to forward my call directly to an AT&T support rep.
It's unexpected to see an AT&T rep provided unlock code so fast. But yours phone came back locked is understandable, since its motherboard had been replaced. I think the IMEI is also changed as well. In the past, usually if motherboard was replaced by Samsung then the IMEI is clean and ready to unlock with AT&T device unlock portal, so even you didn't get it unlock at that time, you can just go to the link above to unlock your phone.

TMobile carrier boot screen on different network

I purchased a Galaxy note 8 from Verizon years ago. After being with Verizon for a year I switched to TMobile to save some money and I brought my Verizon note 8 with me. I used the note 8 on TMobile for another year then I switched back to Verizon and got the pixel 4xl. I sold my old note 8 to a friend who was using straight talk as his carrier. The TMobile boot screen still pops up and he still get messages from T-Mobile and he doesn't have data when he is talking on the phone. Is there a way to fix this? The phone is unlocked and paid off. TMobile says they don't know how to get their stuff off the phone. Any help is much appreciated.
