    In the past couple of years, there was a big issue when you swap SIM cards from one carrier to another where as iMessage stopped working or you did not get the activation email. This happen even when you swap back the old SIM card.

    Example:

    I am planning to move from T-Mobile to Verizon but will be doing testing first, so what I'll be doing is:

    1). Swap out my T-Mobile SIM card and replace with Verizon Pre-paid SIM card
    2). Test
    3). If work, swap out Verizon Pre-paid SIM card with Verizon Post-paid SIM card

    Does anyone know if the iMessaging issue still happening? If not, what is the proper steps to activate/deactivate iMessage with different SIM cards?

    For me, when swapping my two SIM card, Apple will almost always try to send an SMS to somewhere during the process. This has resulted in international charge once before. (I need that SIM for certain apps to work)

    But perhaps I don't have the situation which Apple fails to send activation SMS.

    Where did Apple send the SMS to? Old number?

    No. Apple uses the new number to send SMS.
