This has been happening to me in the NE (very near downtown) since January. I get periods of Searching... or No Service in areas that just a few months before had not been giving me problems. Usually toggling airplane mode solves the problem, but overall this problem is very frustrating as I need to receive important work calls and other calls and find that I have missed them and they have gone straight to voicemail. Moreover, I have changed both my SIM card and my phone, still with no improvement. My wife has the same phone with Rogers and never has this problem. I am considering switching away from koodo.
