I have three lines on TM, all used to get decent but not great coverage at home and in the neighborhood (Lakemont in Bellevue, WA). For past few days, I hardly get 1 bar on my two Windows 10 Nokia phones, but my iPhone 7 gets 3-4 bars, I switched the sim cards from my Win-Nokia to Win-HTC, Win-Samsung phones, still barely 1 bar. But then I switched to a 4-year old Samsung-Galaxy-Android, I am getting 3-4 bars! The three phones (iPhone, Android,Windows) are on my table now next to each other, still the bar strength is 4-4-1, respectively. Anyone have this experience?
