Unlocked s3 and wanting to switch to prepaid - T-Mobile, Samsung Galaxy SIII

hey everyone i'm new to this so please bare with me..I have a T-Mobile Samsung galaxy s3 and I got the unlock code off eBay for a pretty cheap price, so far it looks liked it accepted it . I wanted to switch over to net10 or simple mobile. I heard about if not paying my T-Mobile bill they will block the imei number. If so will I be able to use it at all on those carriers I stated, or will I just have to use it on H2o or Att.
Also as far as the apn settings is there an application that will help? Thanks in advance

OK thanks a lot. Also I did hear that simple mobile is run by T-Mobile so will it work on simple mobile if Imei is blocked?
Sent from my SAMSUNG-SGH-t999 using xda app-developers app

Yeah it will work. Simple mobile doesn't even ask for imei. Only if you want to put it there is the option but its not required

Ok thanks alot for the info

To be fair, they're going to know your IMEI even if you don't disclose it to them during the sign-up process. Just by using the phone it will send that information out when you communicate with their cell towers - so I'd imagine if T-Mobile shares its block list with Simple Mobile, it won't matter if you disclosed the IMEI at signup - they're going to know it anyway.
That, and the Big Four is actively working with the FCC on a cross-carrier database - so unless that falls through at the 11th hour, that's on the horizon in the next year or so.
Just sayin'.

What do you mean by the big four carriers is working with the fcc in the next year? Please explain, thanks

Yeah your right. I just called simple mobile and they said even if it is blacklisted for not paying my bill, it will still work because its an unlocked gsm phone so it wouldnt matter, just pop in my sim card and I would just honestly get edge network which is slower than 3g speed.
Sent from my SGH-T999 using xda app-developers app

It will work if they don't use T-Mobile IMEI blacklist and continue not to do so.
It seems like that's the case, at least for now.
Just saying, it doesn't have anything to do with if the phone being carrier unlocked or not - IMEI is tied to the phone's hardware, not the SIM card.
I went through something similar with T-Mobile, and most of the reps don't know what the block list is let alone how it works.

***T-Mobile GAB Sim Card***

So ive been doing researches cuz i would like to get my "WIFI Calling" to work...
So i called T-mobile to see they had a solution for me...
And this is what they said:
They told me that the Normal Sim Card i have is not supported to use WIFI Calling.....
So the guy said that i need to buy a "GAB SIM CARD" that supports WIFI Calling and its price is $20
I even Google it to see how they look but didn't find it...
What do you guys think?
Should i buy it or is there another way to do it without buying this SIM CARD

sim cards are and should be free from t-mobile. go to your local store.
BUT, when you got your phone (if you bought it from t-mobile) it should have come with a sim card, that supports wifi calling. That's what I had to do, had them activate the sim that came with my galaxy s2, and then started using it instead. and bam wifi calling
It sounds like you went to a dealer.
Not every t-mobile store is operated by t-mobile. Many of them are dealer stores that charge whatever they want.
Dealer stores are usually pre pay only, but there are some authorized to collect commission off contracts and that have access to t-mobiles "quickview" account software. (Quickview is the system the infamous SOC codes are set up in.)
A lot of dealers incorporate sleazy practices and do not conform to the standards set by t-mobile. They do things like charge egregious amounts of money on SIM cards, and may not honor the return polices set by t-mobile. They also sell lots of "out of production" phones they get at good deals ex. Lg-g2x for under 240 dollars wholesale and resell for over 550.
Call t-mobile and ask for a corporate store, not a dealer store.
T-mobile seems to allows this since "money is money"
As for the SIM card I don't think it has anything more than you're IMSI and your half of the encryption cypher, (for establishing a network connection) and some limited memory regarding contacts and previous network connection frequencies . . . The fact that your SIM card did not support wifi calling is most likely because t-mobile identified it a a card not to allow access to for whatever reason. I don't believe there is a technical deficiency in you're old SIM preventing such a technology, or support in you're new one for that matter.
But then again, I am no expert. If anyone knows more please share.

Initially they told me $20 too...but I explained to them in a very gruff voice that I give them over $200 a month and I am completely done with my contract and would be happy to switch carriers. Manager came out and gave me the SIM. Since that day I always go to that store and the Manager normally sweetens my purchase with a discount on what I buy.

T-Mobile is actually using new type of SIM cards - GBA cards that allow WiFi calling via the SIM, and the device must support it as well - you must have a GBA SIM and a compatible device for this type of WiFi calling to work.
If I remember correctly, only the Galaxy S2 and the HTC Amaze support WiFi Calling through the SIM, rest of the devices have it using the app.

Tmobile 3g plan

I had a hd2, but I bought my friends tmo samsung galaxy s2. At the moment I can only access the internet through wifi, when I try to go online with just the phone with my plan it comes up.. your data plan does not support this device. Anyway I can get around that and still be able to use my 3g data with this phone or do I have to actually update my plan to 4g for this phone in order to get data again?
Have you tried going into advanced settings and turning off 4g? The settings would be accessible from the phone dial pad with a particular code.... Something like *#0011# I can't remember the exact code but if you poke around for it I'm sure it's been posted before.
Sent from my SGH-T999 using xda premium
edit. Just thought about it for another second... You would probably have to tell the phone to use edge only. Not sure it would work, but I am sure it would suck. I would look for it in the settings, but if my girl woke up and I was rummaging through her phone I might look like a creep.
Hmm you must be on the old grandfather data plan. TMobile blocks any of their 4g devices from utilizing it. If you want to continue using your old data plan you would need the telus version i think. I know this is true with the sensation and amaze, possibly other phones too...basically any non TMobile branded phone.

In the united states, last I've read, is that they just fine you a hefty fine. And I think getting banned from whichever carrier you were using. It's not like you go to jail. Unless something gas changed.

I would try the different apn people use to get around throttling; in the Hd2 days, data was 3 different packages: smartphone (windows devices), G1 (which would eventually become Android), and BlackBerry; if you mismatched them, your data would be touch and go at best.
Back then it was an easy fix; to do so now, you'd have to have them change your plan to the new ones WHICH WILL EXTEND YOUR CONTRACT LENGTH but will not affect your upgrade eligibility.
The hd2 is still such an amazing phone.

Does att block imei?

I have been chatting with this girl on Craig list who wants to get rid of her sgs3 to help pay for an iphone later this week....
I know all the sprint / tmobile phones on Craig list eventually are blocked for non payment / reported stolen...
To my understanding att doesn't care about this stuff... At least last year the un didn't..
Is that still the case? Don't want to get this good deal on a phone just to have to unlock and sell it again..
Want to buy it for my sister

What if somebody opens an att account.. Sells their phone on Craig list and stops payments to it.. Will att block the phone they got with the contract?
Sent from my SAMSUNG-SGH-I747 using xda premium
Just meet up at the store make the purchase there. If the seller is unwilling to go there then tell them to screw off. They will have security cameras all over the place so there is evidence that this person is selling you the phone; and you will also have a witness that this is taking place so if later they claim that they never sold it to you and it was in fact stolen then you have some evidence in your corner. Legally speaking nothing is concrete but you have to think as litigious as possible because scum is everywhere.
And if you want to get really ridiculous you could type up a document stating that they will in fact pay in full the remainder of the contract and/or pay any fees necessary to keep "the specific ImeI" from being blocked from att service. You would have to have them sign it in front of a witness and a notary. If I were spending more than 400 bucks I would get this ridiculous. Then if you have to take them to small claims court this contract will be as good as any other contract and any judge worth a damn will force them to pay the damages.

[Q] Simple Mobile Support?

Hey you guys, I've been using the 40$ Plan for SimpleMobile and will be soon buying a Galaxy S3. I will unlock it and use it for SimpleMobile. I was wondering if it supported and how the connection is. I know the connection and internet speeds can vary depending where you are, so I am in Boston Massachusetts. If anyone could help that would be nice, thank you very much!
Ive had simple mobile a long time ago now i have t-mobile also u dont need to unlock it because simple mobile runs same network as t-mobile but yea its cheap and all but speed are like what ever u know its okay but u get what u paid for

I have my daughter on simple mobile and its fine. The only thing you have to do is change the apn but there is actually an app on the market the changes it for you. The other thing is you may have to cut a sim card down to size because I was told micros weren't available but that was a few months ago so that might've changed.

I've had simple mobile before and had no problems what's so ever. I'm actually thinking about going back to them after my t mobile contract expires in February.
The only reason I went to t mobile is because at the time they were offering the HTC hd7 for free with a new account.. Lol btw that phone sucked.
Now they do sell the micro sim cards. You can get one off their website for like 12$ or on eBay for about 2$.
So no manual cutting needed. If it's a t mobile phone no need to unlock it for simple mobile. And another thing you have to adjust is the apn. But that is described step by step on the simple mobile website.

Hey guys should I be careful buying a used tmobile phone? How can I be Shure the is good to use? Not stolen or in the blacklist or what about if I buy the phone and then the seller report it stollen. Will tmobile disconnect my phone even if it is on simple mobile? Is there a safe way to do the transaction. Lots of questions. Thanks
well, it is not safe, if the phone report stolen or blocked it by tmobile, you can't use it with simple mobile. and there is no way to know if the phone ok or not, it will works for a couple of days/weeks/months but once tmobile block it. you will be sorry. anyway I bought mine from amazon, I talked to them first about people selling phones on amazon and then the phone gets blocked. they put a note in my account that if the phone got blocked I can return it back for a full refund no matter how long. and btw mine is used.

T-mobile phones are the worst to buy used because it can be blocked for 2 reasons, unpaid EIP and phone reported stolen. I almost got burned but luckily I was able to tracked down the previous owner. The phone worked for weeks before it was blocked. Scarry.
This is currently my experience.
I own an AT&T Galaxy Note 2 that I just got yesterday. I got it unlocked, and right there I'l put Simple Mobile on it and it worked just great with the only exception that I get only 2G on it and I'm on an area where most T-mobile users get 4G.
So got somewhat disappointing but didn't give up. From there I rooted it and I flashed a T-mobile SGH-T889 ROM on it and it ROM itself works, but with Simple Mobile I still get only 2G.
From here, I'm thinking the only thing I'm missing is the Radio (or Modem if you wanna call it that way) for a T-Mobile phone since I'm suspecting I'm still using an AT&T radio.
I haven't done enough research to see if I'm right on my theory. So as soon as I get back to the kitchen I'll flash a T-Mobile Radio and see if that works.
