Sorry for the issues.
10 minutes in my case, but likely I would leave the hotel/apartment parking lot and just kill some time driving around the block.
Regarding "dual phone/text" phones ... even better if you have a personal family phone and a separate hobby phone.
Inexpensive and that way you don't expose the hobby number to family. Yes, I know about Google voice.
And you have a backup phone unit just in case... ijs
