Hi all. Imminent trip to Florida (April) and never used LAANC before. I am unlikely to want to fly in Controlled Airspace but just in case! I have AirMap. All looks straightforward but just a bit worried about what phone number to give them. I use my iPhone 11 to fly with but it has a U.K. number and SIM. And, when I fly, I have it set to Airplane Mode. I realise I can make the application before I want to fly. Am I good to give them my U.K. number or would I be better off buying a preloaded US SIM and use that whilst in the US? Hope this makes sense. PS all signed up and FAA Registered and have TRUST. Add to this the roaming costs in the US for a U.K. phone-could cost more than our hotel!!
