I was recently stuck for 10 hours in the middle of nowhere Colorado on the California Zephyr. No WiFi, no cellular service (less than 1 bar or SoS and 200 passengers pinging the tower). Had to try satellite to send text messages about our delay, and staying in contact with a satellite was laborious, tedious, and frustrating. Plus, the satellite text message took minutes to send and then minutes to receive if someone responded, all the while trying to maintain contact with the satellite. Satellite communication on cell phones is not ready for Prime Time. iPhone 16 Pro Max.
