CUBOT unlock smartphone MAX3

Worked for 1 week and then blah! Returned without any issues

I an looking for another phone if it says unlocked at the top then it says t mobile as carrier can I use us cellular or not

UPDATE: I have to return this phone because I couldn't use it after 5G came out and 3G was discontinued. I bought it with the idea it would be great for 4G, but I could not make or receive any phone calls. All other functions worked, but, REALLY?? No calls? RETURNEDThis phone is big, but not too heavy. I love it!! May give up my tablet for it!It has a quad camera, including slow motion. Now I need to find a great case.

About 90% of websites that I went on to would not let me on, screen message would say "no internet check your internet connection". Also when I did get onto a website it was very slow, would switch from 4g to 3g a lot. Also for a 5000mah battery it didn't last a full day, it drains very quickly,in 10 minutes of sitting idle it would use 6% battery.
