Fake roaming

Is it possible to make my phone think that it is roaming?
Sent from my SGH-T989 using Tapatalk

trying to get out of your contract this way wont work......tmobile is already aware of the threats people are using as roaming capping data.....in a unlimited data plan...contracts states thete allowed to make changes within..sucks.....

Just find a dead spot on there coverage map and say ur moving there since they can't provide service they have to terminate ur contract

i tried that as well...they will need a bill to verify your address....lol...and they told me you should have checked the coverage map when signing co tract...these tmobile guys wont let u loose unless your deceased .....

Fuuuuh that sucks that's why I don't like contracts

Start a series of dialogs with customer service regarding dropped calls and terrible service signal. Call each day for a week or so, eventually they will "pass it to the engineers" and you can still call and complain. After a week or two file a case with the Better Business Bureau. They will ask you what you want them to do, just tell them you want out without the ETF. Worked for me.

I guess that's what I will have to do.: I have already called about that maybe four or five times and nothing. I think you're right and that in should file with bbb. Reason I want out is because I am moving to a crappy coverage area and frikin tmo keeps charging me $100 more than what I should be paying. Att gives me that same plan, but for half the price.

***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

That's bull****, they should have updated your SIM card when you bought the phone off of them unless of course you didn't buy it from them

Sent from my SGH-T989 using xda premium

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.

Why would you pay for it? They are free

Because TMobile likes to get every dime they can. Usually they are free in the corporate owned stores.....franchises have the option to charge

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.

Please help....

I have a friend that he is selling his Tmobile GS3 but he didn't pay his bill so Tmobile blocked the IMEI so now he can't use it and he wants to sell it to me for 350, I think it is good price compare to what people is selling right now. Is there anyway I can unblock IMEI so I can use it on Tmobile network? Thanks.

If he pays his bill they should unblock it. Other than that the only way you could use it on T-Mobile is by changing the imei which isn't really legal.

He switched to pay-to-go as type of service, he doesn't have tmobile any more, he just totally doesn't want to pay the rest of his bill at all. One more question, since I have another GS3 and back up the IMEI on the working GS3, can I restore it on the blocked IMEI GS3? It likes both phone have the same IMEI, will it works that way?

or can anyone show me how to change the IMEI? Thanks.

Unlocked s3 and wanting to switch to prepaid

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

Just means u cant use the phone back on t-mobile other company's dont care if the phone has bad record I had and s3 before I got the one I have now it could not work with tmobile because the person that sold it to me did not pay bill but u can use it on att simple mobile net 10 any (gsm) cell phone carriers

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

Sent from my SGH-I747 using xda app-developers app

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.

Wallmart has a cellphone company fairly new, called FAMILY MOBILE. Bottom line... activation kit is only 27$. Uses T-Mobile towers and speeds seem to be 4G to me...I technically just pay 27$ a month and get a new number every month.(I dont pay the bill...no contract )

If you value privacy it is... theres plenty of reasons that may be positive. Doesn't necessarily mean it outweighes the inconvenience. But for 27$ Im real cool with that. No complaints. And if you were to be monitored by tyrannical government it helps. If a stalker is out to get you ir helps...avoid bill collectors lol ect.

Go to Walmart. ...hit the electronic dept. ask the clerk for a FAMILY MOBILE START UP KIT. If you rooted your phone and your on XDA, then you probably able to follow the step by step instructions to activate the chip with the customer rep. Its 27$ to start....if you pay the bill, its like 44$ a month. I dont. I just get a new kit. Dont care for the number to stay the same.
