It’s unclear.
Last I checked for this (and it’s been a while), this was the frequency distribution in my region:
- base 4, 7 (1700/2100, 2600 MHz: Bell, Rogers/Fido, others?)
- base 10 (700 MHz: Vidéotron)
- base 13 (700 MHz: Bell, Vidéotron, Telus)
- base 17 (700 MHz: Bell, Rogers?/Fido)
The overlap with the FP3 specs (“Bands - 1, 2, 3, 4, 5, 7, 13, 20, 26”) are:
- base 4, 7 (1700/2100, 2600 MHz: Bell, Rogers/Fido, others?)
- base 13 (700 MHz: Bell, Vidéotron, Telus)
Which means you don’t get 700MHz with Fido, for example, but might get coverage with the others.
My experience with 4G (and even 3G) with the FP2 is that coverage is also spotty anyways. From what I can tell in the specs, the coverage with the FP3 is better than the FP2, which only had bands 3, 7 and 20 covered. So if you are happy with the FP2 coverage now, you might be happier with the FP3 in terms of connectivity, which is good news…
