There are of course a number of factors at play when it comes to signal strength. If restarting your phone or resetting your Network Settings doesn't help (and you're obviously in an area where our network should be sufficiently covered; downtown Calgary), the first thing to check is our page at www.telus.com/status as it shows any issues reported in the area...if there are any, that is. That all being said, if nothing seems to be improving your signal, your best bet would be to visit the nearest TELUS store so our team can take a look in person or by calling our Mobility team so they can assist!
