The second SIM card will not work and it is called unsupported SIM card on the iPhone. In this post, I’ll show how to fix SIM not supported on iPhone.

If you’ve tried to enter the second or third SIM card you might have probably come up with the error such as, “The SIM card you currently have installed in this iPhone is from a carrier which is not supported under the Activation.” This isn’t the only problem your iPhone might have with the SIM card.
