Thats what's getting me perplexed because T-mobile is merging with metro pcs and they're getting lte from metro pcs . How would they convert it to gsm ? Or is lte universal?

well metro does use some sort of sim inside their 4g phone i know its not a sim card it just used for 4glte purposes so maybe their 4g runs off some sort of gsm system maybe ??

LTE is based off of the GSM standard but it uses a different radio interface, so it requires a its own antenna, and so could be added to CDMA phones. Because of this, since T-Mobile and Metro PCS will use the same 1700 Mhz spectrum, their services are compatible.

The LTE is run off the sim card but it does not have phone info on it, I am not sure if you could pull the card from one phone and put it in another and get service.
My wife has a metro lte phone but we dont have another to try it on.

Yes I can confirm the metropcs sim cards are interchangeable
Only if they are a cat3 microsim though.

Here's hoping this was a stock Note!

I have an AT&T note 2 running on T-Mobile. I've also got the hack working to enable T-Mobile HSPA+ Frequencies (1700/2100 in the AWS band) to work. My understanding is that LTE should work when it comes to T-Mobile.
As I understand it, AT&T LTE is one of two forms. Most of their LTE is 700 MHz on. However, some of it is DC (dual channel) 1700/2100. This is the same frequency T-Mobile is using. Consequently, it should work fine. Since it hasn't lit up in OKC yet, I can't verify that.
note - the Dual channel thing is a technology that allows for better speed without requiring a continuous frequency band. For example, I can't get 2100-2120 Mhz, but I can get 1700-1710Mhz and 2100-2120 Mhz. With DC capabilities, you get the advantages without requiring a continuous range of frequency.

I doubt that one is for download and one is for upload as both are the same freq range (5Mhz or 10Mhz). Considering the large amount of traffic is download that would be very inefficient. If it was that way, the download would often get congested and the upload would remain relatively free. This would mean on speed tests one would often see much faster upload speeds than download. That isn't the case.

For me, if I were to get a 2 I'd just get a TMobile branded one (or international to use AT&T prepaid tablet plans)- I'm looking for a used 1. I really should have bounced on one of those original AT&T Note's I saw for 250.
I bought the AT&T N2 because it supports wireless charging accessories while the T-Mobile one doesn't (sort of does with a hardware hack). Plus, I got it Brand New In Box for 550 on Ebay. not a bad deal.

Yes one is upload and one is download. The reason you don't see faster upload speeds is because it is the limitation of the hspa+ technology (~2mbps max upload speeds). That is one of the reason for the move to Lte. It can handle more bandwidth both upstream and downstream.

after looking around for a while, I finally found mention of this on the HSDPA wikipedia page. Strange that there is this limitation on upload speed despite the same amount of bandwidth. Maybe it has to do with packet construction verses de-construction. Maybe construction is more difficult and so the phones can't pack the data as well as the towers. Consequently, slower uploads. Just an educated guess.
