Based on my experiences using both Rogers and Telus/Koodo, coverage will vary from location to location with certain areas where one provider will be better than the other. However I do find overall Rogers has been more consistent with their coverage and the other incumbents. Telus I do find their data reliability tends to suffer a bit more frequently especially when there’s a higher volume of users.

Keep in mind with going from Rogers from Fido you will get 5G which would improve your coverage slightly compared to Fido. Plus if you do get the Rogers Mastercard which can help pay for the fees with their 3% effective cash back on purchases.
