Two apps are available for the inreach mini 2. I have explore already working on my PC with the inreach as well. Do I need messenger? Also, looking at the messenger app, it requires a 2FA like code to be sent for install. I'm going around the world and my phone number will be changing in every country I visit. Keeping up =with 2FA on banking, gps, accounts and everything will be a nightmare. For the messenger app, is this easily updated or can there be a secondary way to handle 2FA on this app? Thank you.
