Ordered 7t through Amazon, have questions.

[oakleyguy89]

Hey guys I am getting my wife a 7t. I was going to get it from their official site but noticed that Amazon had the 7t with 256gb ROM for cheaper. I noticed in the reviews a few people were complaining its the Chinese model (HD1900) and that its not global version. Should I cancel my order and just get it from one plus' website or am I fine with the one coming from amazon?

Don't take my word only but I don't think there is a specific model for China. I believe there is only a global model, european model and indan model. And a T-Mobile model if you want to count that. So I would think you probably got the global model and should be good but let someone else come in here and confirm it

You should be fine, I have the same model. all I did was change the rom to the global rom because it does come with Hydrogen OS. And also it should work fine with US carriers, I tried T-mobile, Verizon and AT&T

I think the basic differences between various variants are the network frequency bands. The question is which bands are supported in your region. On the basis of that, you can choose the correct variant.

I am from India and I ordered 7T from amazon and I got the Indian variant (HD1901).

This.

HD1900 is missing bands 25, 30, 46, 66, 71.

25 is a superset of 2, currently used by Sprint and potentially by TMobile eventually.
30 is important for ATT.
66 is a superset of 4, used by all the main supported carriers, although generally you'll be fine with just band 4.
71 is TMobile's new lowband frequency.

Yes, the hd1900 would likely work fine with all the carriers, especially in urban areas. However, reception may be spottier (lack of lowband 71), or bandwidth may be lower (4 instead of 66, missing 30).

My guess is the hardware is the same, but there hasn't been much effort to figure out how to unlock the other bands.

Ah, I cannot confirm that whether the hardware is the same or not. But in other threads, people are saying that if you flash the roms of other regions you can unlock those bands. There are many tutorials out there on how to unlock all bandwidths. I'm giving some useful links. Read them. Maybe you can find what you're looking for.

Well i got it the 7t today and it works great with my carrier (Cricket but it shows AT&T in the menu). Im really impressed with it especially for paying less than $500, its a bit snappier than my s10+. It already had Oxygen 10.0.4 installed and I just flashed 10.0.7 global and it gave me an OTA for 10.0.9. Really nice phone!
