Greetings Jrelbebe, thank you for finding the time out of your bustling day to ask us your question about the Samsung Galaxy A15. The advertised unlocked Galaxy A15 works on the 4G LTE and 5G wireless networks. It is actually compatible with Verizon as well as AT&T, Boost Mobile, Cricket, Google Fi, H2O Wireless, MetroPCS, Mint Mobile, Simple Mobile, T-Mobile, Ting Mobile, Ultra Mobile, and US Cellular. Considering this is an unlocked device, we suggest reaching out to Xfinity Mobile to inquire if this device would also be compatible on their network with the information that has been shared above. If you think of any other questions for us, do not hesitate to reach out to Samsung Support at your leisure. Thank you for being a dedicated Samsung customer. - Debra
