Q: iPhone sends paid SMS to activate iMessage, what happens when SIM card is changed

According to https://support.apple.com/en-us/HT201422, “If you're using an iPhone, you'll need SMS messaging to activate your phone number with iMessage and FaceTime. Depending on your carrier, you might be charged for this SMS.”

Does anybody know answers to any of the following questions, mostly applicable to international traveler:

  1. If one changes SIM card in the iPhone (iMessage/FaceTime already enabled), does it always automatically send this paid SMS to activate iMessage/FaceTime for the new cell phone number, without additional confirmation?
  2. What is the number to which iPhone sends this SMS, how is it defined (to properly distinguish it from fraudulent charges in the monthly bill)?
  3. Does iPhone send one or two SMS when activating both iMessage and FaceTime for the newly inserted SIM card (new cell phone number)?
  4. If one inserts a foreign SIM card (in roaming), would iPhone automatically send this SMS to activate iMessage/FaceTime for the foreign cell phone number, which could be more expensive in roaming than for local number?

Thank you.
