Salutations Del, thanks for reaching out with your question about the Samsung Galaxy A36 5G. The advertised unlocked Galaxy A36 5G is the U.S. version of this device. It's compatible with the following U.S. wireless carriers: AT&T, Boost Mobile, Cricket, Google Fi, H2O Wireless, Metro by T-Mobile, Sprint, T-Mobile, US Cellular, Verizon, and Visible. We recommend reaching out to a compatible wireless provider to inquire directly with the carrier if this device would be functional while in Jamaica. If you would like further assistance afterward, do not hesitate to reach out to Support. Thank you for being a valued Samsung customer. - Debra
