The radio frequencies E.g. 800 MHz versus 850 MHZ.
Search STA100-3 STA100-1 STA100-4 etc to see all the frequencies for other countries.
This STA100-5 is best for Canadian carriers because of the radio frequencies it uses.
The STA100-5 might be the only one distributed in Canada, for all I know.
Other than the radio frequencies, there might be one more thing, in one model: wireless charging.
Hope this helps.
