Question for those with more experience! BF and I are hoping to take advantage of Best Buy's "$150 off when you activate an unlocked pixel 3a" deal. Problem is, I have T-Mobile, which Best Buy doesn't deal with. He has Verizon. How difficult would it be if we bought the 1st one, activated it on his line, then bought the 2nd one and did the same, then I take the first to activate on my line. I know in theory it should be very easy since they're unlocked, but it's our first time buying unlocked and first time buying from Best Buy. So I wanna be sure I'm not missing any details lol
