No! This is the #1 roaming trap. Jamaica is an independent country and is NOT included in any US, UK, or Canadian domestic plans. Most home carriers (like AT&T, Verizon, T-Mobile, or UK's Vodafone/O2) will charge you expensive international "Day Pass" rates (e.g., $10-$14 per day). A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper.
