You seem to be ignorant of the technology I am using.
My iPhone's phone number is 6010.
It is impossible for iMessage or Facetime activation to ever succeed with that phone number, even if another carrier did offer a similar service to SIP2SIM, because of how Apple have designed activation.
If you were an Apple representative telling me to switch carrier, knowing full well what I use my iPhone for, that would be a clear case of misselling.
If you don't know why an iPhone would try to activate iMessage and Facetime when both are disabled, don't suggest I switch to a carrier that supports iPhones. Instead, tell me whether this is (a) a bug in iOS (and where to find more information), or (b) where the setting is to stop the sending of these SMSs.
