@chasesdad. They don't need to activate an unlocked phone. All you need is a sim card. I bought an unlocked 10 and 11 and used my sim card from my 7 pro and it worked fine. Can't comment on the pad though.
OnePlus is now tipped to have designed its next top-end smartphone with "user feedback" on its previous generations in mind. To that end, the "12" is now believed to boast an updated rear camera hump packed with in-demand features such as powerful optical zoom. It may also charge even faster than the current flagship 11.
