A lot of plans in the US and Canada charge you money when you receive a call.
FWIW, in the US, although that's technically true, it's in a very roundabout way.
On almost all US plans, if you're talking on the phone (regardless of if you called someone, or they called you), you're using "minutes".
Depending on the time of day and who you're calling, the minutes you spend on that call can be deducted from the amount of minutes your plan comes with. The only time you get charged money is when your plan runs out of minutes.
Typically, the only minutes that count towards your plan minutes are the minutes when you're on your phone between 7am-9pm on workdays. After 9pm (and on weekends), minutes are almost always free. Again, it doesn't usually matter if you make the call or receive the call. There are a few oddball plans offered by 1 or 2 carriers where all incoming calls are free (meaning the minutes you spend on them don't get deducted from your plans minutes), but those plans are very niche.
To make it even more fun, most carriers offer a "mobile to mobile", where if you call another person that also uses the same carrier, the minutes you spend on the phone aren't deducted from your plan, even if you're calling during the middle of a workday.
Sorry for the novel, I just didn't want anyone to have the impression that in the US, everytime you answer your phone you are charged money.
