Don't Wait If You Don't Have T-Mobile
While it's great news to see a company like OnePlus finally being offered in-stores and online from a carrier, T-Mobile, exclusive deals aren't good for anyone.
It looks like the OnePlus 7 and OnePlus 7 Pro will again ONLY be available in the United States from T-Mobile. Keep in mind that they will absolutely work just fine on Verizon or AT&T, but only T-Mobile is offering the devices.
This basically limits how many people (other than enthusiasts) ever see or know the phone exists. Google had the same problem with the Pixel on Verizon, and finally realized they needed to offer the phone on all carriers.
Basically, it looks like T-Mobile will be the exclusive carrier of the OnePlus 7 and 7 Pro in the US again this year. Once everyone gets a look at the stunning OnePlus 7 Pro, though, we have a feeling other carriers will offer the OnePlus 8 in 2020.
