Apologies if this has been asked before, but I couldn't find it with a search. I'm traveling to England next month and planning to get a local SIM for my iPhone 5s's rather than paying Verizon's international roaming. I understand I'll have a different phone number as long as I use the new SIM and that my current phone number won't be active. Here are my questions: Will Messages still recognize the iPhone or will it require the two-step verification process? If it does want to verify, how can I configure this since it will try to send the code to my number that isn't active? Or am I overthinking this so that it won't be a problem? Thanks in advance for any insights.
