How do I switch iPhone carriers?
iPhone 11 has a SIM card from my old iPhone 6. While attempting to transfer the iPhone 11 from Verizon to Xfinity, I received a notification "Your SIM is Not Supported, The SIM in your old iPhone does not support eAIM transfer. Contact Verizon for asistance". Verizon tells me they will try to unlock the SIM but it may take up to 48 hours to do.
If they are successful unlocking the SIM, how do I transfer the iPhone from Verizon to Xfinity? Do I need a new SIM card or can Xfinity use the one from my iPhone which I think is needed to keep my cell phone number?
