I cant seem to find this one using the search so forgive me if its been asked.
Im going to toronto next year for a year and my phone is triband supporting only the 1900 band for north america. What sort of coverage might i expect with it or would it be necessary to get one with 850 support too?
It is the Fido 1900 network coverage but I think it should be the same for Rogers.
The coverage maps on GSM World may not be updated entirely, but Fido and Roger's both have 850 and 1900 Mhz GSM and WCDMA networks. Therefore, you will need atleast a phone that supports ONE of the 2 bands to get network access, but having 2 of the 2 bands will mean you will gain FULL coverage to the network including fringe areas.
GSM 1900 penetration is poor in buildings and undergrounds, where 850 does better. While Toronto has decent 1900 coverage, many of the outer regions do not. You really should get a GSM 850/1900 phone, although many people manage with 1900 alone.
