I use T Mobile. Coverage is weak . It buffer s all the time. Sometimes I can't get a trip because of buffering and sometimes I get lucky close and reopen the app and it's there. Frequently especially in fog can't end trips and gave to go a mile or several to find coverage. This has resulted fairly in several pax request information fare review for excessive time and distance. Is this just in T Mobileand us there a better carriet or is it common among all carriers ?
