Folks there have never been able to text or surf using cell data. "The new 4G LTE coverage is a huge boon to everyone at Naval Station Guantanamo Bay," Captain David Culpepper told T-Mobile. John Legere and Co. reportedly took over from a small private company with "not very good" service, according to a Reddit commenter. "Lots of families on NAS Guantanamo here [and] connectivity is a pain ... the facility is way more than just that [prison and camps], with lots of similar activities and things we get in the rest of the US," says user "nps-ca."

Gitmo residents get the same level of service as folks on the mainland, and a screenshot (above) shows healthy 38 Mbps upload and 26 Mbps download speeds. As of August, residents could buy postpaid and prepaid T-Mobile plans, along with smartphones and accessories, from a retail kiosk in the Navy Exchange store.

In a separate arrangement, T-Mobile recently started offering cellular roaming service in Cuba. That gives vacationing magenta customers access to text, mobile and data, thanks to a deal with the government-run Empresa De Telecomunicaciones De Cuba company.
