Thank you for the reply, but what I don't understand is that this phone came from the T-Mobile store. And I do have a contract with them. But it wasn't bought under my account name. The phone was bought from a friend who worked at a T-mobile stand. So why I don't get 4G or LTE service I'm still puzzled. I am so sorry for being an idiot on this, but I'm really dont understand why?

Every T-Mobile Samsung Galaxy SIII model is the SGH-T999 and that phone itself does not support LTE connectivity

But it does support 4G service, i know this because my sister actually has a TMobile Account and she is getting 4G service on hers. But for me I can only pick up 3G service. So that is question 1.

And for question two, is basically your saying I would need to get a AT&T model version of the phone in order to receive the LTE or 4G service that is provided in my area?

Thanks so much for helping me out here.

I have the tmobile version of the S3 running on At&t. The SGH T999 does not have an LTE firmware. The most you will get is HSPA+. You will definitely need to get the AT&T version to take advantage of their LTE network.

OK thank you everyone who has helped me understand this. I really have no idea why it wasn't registering in my head. I 100% get it now. I also called AT&T and i did a 3G speed test and I'm getting like 700Kbps and 50Kbps up. which is horrible. I don't even think I'm getting HSPA+. I'm like a step below.

So i was talking to him and he suggested that I could get a refurbished version of the phone for $100 and all i would need to do is extend my contract a little by 6 months. Now Since my phone is factory unlocked I could sell my phone and easily get the $100 for the phone plus it comes with a 90 day warranty. And for $5.99/month I could get the insurance package which if something happens they will replace it for $199.00. Which isn't a bad idea. But he said a lot of times people buy the phones and decides they just simply don't like it or would rather have a different one and since it has been used, they have to advertise it as " refurbished."

So what my question is, is has anyone ever bought a refurbished phone and had success with it? Or has anyone had any horror stories with the getting a refurbished one?

Thanks in advance everyone.

If you are still trying to sell your SGH-I999 I would be very interested. I am in the opposite situation as you I have a Gaqlaxy S II and went to t-Mobile and now I don't have 3g/4g so I have to find a T-mobile Phone. Please message me if possible
