Ring protect plan and emergency contacts (foreign phone numbers)?

Hi, I know that with my protect plan I can register 3 phone numbers as emergency contacts. In my case, there's my own number, my wife's and my brother's. We all live in France, so all numbers are with +33 as country code. Let's imagine I travel abroad this summer. I normally use a local (foreign) sim card to avoid paying expensive phone bills when I travel abroad. In that case, may I just register 3 new phone numbers as emergency contacts during 2 or more weeks and back in my country, register my usual numbers back ? Are we allowed to get emergency phone calls during an alarm alert when we travel abroad at no extra cost ? Thanks.
