Its in perfect condition just bought it they sent mecwrong one but I need the Lm-V600-AM

So I bought another LgV60 my old one was an Lm-V600Am which abused my old Straight talk att sim in with no issue, I purchased another online that said Att unlocked but I received an Unlocked Tmobile LM V600TM, I can use the internet but im unable to make phone calls or texts, ive emailed the seller and they just keep saying it will work with any Sim and network because its unlocked, I have searched and searched, ive tried changing apn , ive gone into phones secret settings but nothing is working. Has anyone got a straight talk att sim to work in this phone, if so please tell me how.

cant get past roku spaceship screen, continuous flashing to black and back to screen , roku just keeps flashing on spaceship screen for days can't go to any other screen tried changing cords resetting even moving to another tv in another room still does the same thing, I've seen other posts tried all the suggestions , I've had this stick for couple months and just started doing this, I've tried leaving it on to see if it would run through an update but I don't see how it could assuming it's not connected to WiFi since it can't even start
