Does Sprint Work in the Dominican Republic?

No — Sprint's native network does not operate in the Dominican Republic. Sprint (now part of T-Mobile) has no domestic infrastructure there.

Roaming Option (Historical)

Sprint previously offered an International Roaming Add-on: $15/day for unlimited talk/text + 1 GB high-speed data (then 2G speeds). This was a pay-per-day travel pass, not a local plan.

Current Reality (Post T-Mobile Merger)

• Sprint brand retired (2020); customers migrated to T-Mobile
• T-Mobile plans (Magenta, Magenta MAX, Go5G) include free international roaming in 215+ destinations — Dominican Republic is included
• Benefits: Unlimited texting, 2G data (5 GB high-speed on MAX/Go5G), $0.25/min calls
• High-speed data passes available for purchase

Better Alternatives for Extended Stays

• Local SIM: Claro, Altice, Viva — ~$10–20 for 10–20 GB + calls
• eSIM: Airalo, Holafly, Nomad — instant activation, data-only plans
• Portable WiFi: Rent at airport or pre-order

Bottom line: If you're on a current T-Mobile plan, you're covered. Old Sprint-only plans? Contact T-Mobile to migrate.
