iMessage & Facetime Activation
i bought a second hand iPhone and everything is works fine except the iMessage & Facetime activation.
it's saying "An error occurred during activation, try again"
i have tried all methods including auto update time & date, software update, i have credit on my sim card.
my career support sending text overseas. i don't know what's wrong with iMessage & Facetime!
iPhone 5s, iOS 12
