No. The requirement to have them turned off from before takeoff to after landing is an archaic rule. They don’t work anyway once airborne, and once the groundspeed exceeds a certain value, the cell towers don’t process their signals. Also, Cell towers are designed to have a horizontal beam, not a vertical beam, so the reception capabilities quickly drop below the required minimum signal strength, once above a fairly low altitude.
Here’s a tip to make phone call while airborne. Get on the aircraft’s WiFi. Use the FB messenger app’s phonecall feature to make a crystal clear call to anyone else with FB messenger. Now you can be annoying all of the time!
