iPhone 7 given to friend
I gave my old iPhone 7 that's been offline for a couple of years to a friend for him to use activate before doing so I erased all content and settings and signed out of Apple ID
then I had ATT unlock the iPhone using imei
i received confirmation that is unlocked from ATT
then I gave it to friend
After giving it to friend I thought about the Find my iPhone setting
so I signed into iCloud.com and in Find my iPhone I removed the iPhone that was showing as offline
Question is
Did I do everything now for my friend to put his new SIM card with new phone number from Consumer Cellular "Bring your own Phone" in the iPhone 7 Plus I gave him?
thankyou
