I can't send or receive texts or email, again, even though I show 2-5 bars on the phone. On the latest iOS and all other software.
Is anyone else noticing anything similar?
Specific planes have different bodies that block signals, whether the door is open or not. It’s the body of the aircraft inhibiting the signals.
Also you shouldn’t be avoiding WiFi due to security concerns. Use a VPN, buy a 30 day trial. Avoiding is the wrong security measure to use. If someone wanted to hack you, going through your cell’s phone network or open wireless connections isn’t much harder.
To be honest, it’s probably just network congestion while you’re in the terminal. Number of users and number of available slots. This occurs at lax as well while on the taxiway. If it’s just data that’s slow, sometimes LTE networks can be more congested than 3G (especially at sporting events) as a result of most people having newer phones. Every time I’m at a major sporting event with a LTE slowdown on data, 3G is much more reliable and faster, 100% of the time.
