Hello, i am new to the forum thing and have no idea how to navigate the site. I am sorry if my post (and ignorance) upsets and offends but i need help. i have read through some of the sites do's and dont's and i apologize for for this in advance but i dont have any money to donate so if my questions are above and beyond the call of "duty" to answer feel free to tell me to piss off and i will continue my sad research on my own.

so i am on straight talk and i know that they use a multitude of carriers and to use thier BYOP plan is available and they want you to use the provider that your phone used to use. I, however, am looking to bring an factory unlocked phone (Oukitel U10 to be precise) and am getting nowhere trying to find out if this phone will operate on 4G LTE if i try to use an AT&T sim card. (because i have seen that AT&T elegedly has the best 4G in my area) so i am seeking guidance in my attempt to learn the world of cell phones, providers and how to spot a good phone in these regards.

i know that the phone i want to BYOP uses the following frequencies:

2G GSM 850/900/1800/1900 MHz
3G WCDMA 900/2100 MHz
4G FDD LTE 800/1800/1900/2600 MHz

Can anyone tell me if it is even possible for this phone to operate in North America and what provider's SIM i should use becuase my research has led me in circles and i dont know what to believe because there is a lot of run around when trying to deal with straight talk directly (i have tried).

Any information provided would be greatly appreciated. however as i stated before i cannot provide any donations so if my question is a tough cookie to deal with feel free to tell me to figure it out on my own.

Thank you to anyone who took the time to read my post and have a great day, night, morning (whatever time it is in your neighborhood)
