after erase all setting and content,I can't activate manually with the SIM NO SERVICE problem on iphone 8 plus.I have no damaged on this,just SIM not detected problem.Activating with iTunes is said "Make sure SIM is inserted".
What happened with the ACTIVATION SERVER ever?
iPhone 8 Plus, iOS 12
Please look at this --> If you can't activate your iPhone - Apple Support
If you are the owner or the owner has shared all information with you then to open Activation Lock:- If it is Activation locked, read here --> Turn off Activation Lock - Apple Support Activation Lock for iPhone, iPad, and iPod touch - Apple Support
If you are not the owner and do not have the Apple ID and Password then there is no way that you can get into this iPhone unless the original owner shares the Apple ID and password with you. If you are lucky you can get into this iPhone if they (owner) accidentally remove the device from their apple ID.
