Well, i never had a problem with Fido..
Reception was really good..
No drop calls...
No disturbance...
No call cuts...
Fido gives really good deals on cell phones..
If you dont want a contract..then u have to buy the phone for its orignal price..
It also depends on what phone you buy...
Signal strength, drop calls...etc..all depends on the phone too..
The best thing with fido is that they have per second billing...
So if u talk for 10 seconds...then only 10 seconds get cut off from your total minutes

Another good provider is Telus...It has one of the finest services, but its more expensive...Telus also charges per minute billing...so if u talk for 10 seconds...then they will charge u for a minute..so thats the main disadvantage...

I would stay away from rogers wireless..
Bell is expensive too...and they have crappy plans...

So at the end, my recommendation would be Fido!!!
