My Rogers/MTS cell phone is useless at the airport when airside. Telus works incredibly well but MTS/rogers keep going to emergency mode even though there are windows. When I stand right underneath the Telus booster in the back hallway I get full signal. As soon as I leave that area it just doesn't work, or works very limited. Any chance this Telus equipment is interfering with the MTS signal? Even in the departures area it's not the best.
