Selling phone didn't turn off find my iPhone

I removed it from my iCloud account beforehand. Ouch.

It's sure gone from find my iPhone now.

will I be able to reinstate it so that it could then be erased?

And if I do remote erase it, will the buyer be able to activate it ok and use it?

Thank you. I probably should have hit the Correct Answer button, but I haven't actually tested the solution by ensuring that the phone can be safey activated by the new user.

For sure he must get his own SIM. I was just concerned that Apple's newest theft safeguards have added a new layer of tethering between icloud and a phone's hardware identity, such that, even though it's been erased successfully, it's still tethered to the old account and prevented from being activated with a new account unless find my iphone was formally turned off prior to erasure.

Over worried. The 'tethering' just prevents the erasure in the first place. I entered the password back then already, so the phone should be good to go for the new buyer.

Thanks again. This forum and you experienced people are a god-send.

Thanks!
