I don't know about your area, but when Mobilicity launched in Vancouver it was noticably better than Wind, Mobilicity has now regressed, while Wind has improved significantly.
You could try just getting a Wind SIM card and signing up on the Pay Your Way plan, take a few calls in various places and see how it goes.
The word 'Pentaband' means '5 Bands', from the Greek word 'pente' meaning '5'. For a phone to be pentaband it has to support 5 bands. If the phone has AWS support, it doesn't automatically mean that it is pentaband.
Don't send me PMs for questions that can be asked publicly.
