Can you do trade-in with this deal somehow?
Yes, trade in works. The values are relatively low though. Once you add it into cart, there should be an option for trade in.

IIRC, directly from OnePlus website. It could be BF price. Now shows $300.

Unlocked Samsung models get their OS updates very last after carrier branded variants. So, buyer beware.

Has anyone pop in att or verizon or prepaid sim after cancelling the line with tmobile? Works fine without issues?

I am worried about cancelation charges or contract breach fees especially since it's a credit pull for new customers

OnePlus 8 at $300 is a tough sell now because it was launched in April 2020 and it came with Android 10. $250 is more reasonable. It won't get many more updates in the future. Samsung phones get a ton of updates. Even the cheap budget phones are getting 4 years of updates. OnePlus Nord line is only 1 system update which is understandable to me but tough to compete with Samsung and Apple updates. Samsung have surpassed Pixel with updates in my opinion as Pixel A line gets 3 years. I got a t-mobile samsung A71 5G unlocked phone and I get a ton of updates. I am shocked how good it is with the updates. I don't even use t-mobile carrier.... I say that as I am more of a Pixel fan too.

OnePlus has actually declined when it comes to updates now.

"OnePlus used to be one of the best when it came to software updates, now you've got updates arriving a year late."

I was getting that with my wife's info, even in incognito. Used my info on the same window and it worked.
