Will calling an 877 toll-free number generate a bill to the caller?

Calling a toll-free number will not incur any long distance charges, so a call from a landline phone will not show up on your bill. However, a call from a mobile phone (cell phone) will still use airtime minutes, so it may show up on your bill. The toll-free codes in North America are 800, 888, 877, 866, 855, and 844, with 833 and 822 reserved for future toll-free use.
