One of the best-covered destinations in the Caribbean, with strong 4G and growing 5G across every major tourist zone. Two solid carriers, and one genuinely surprising dead zone on an excursion nearly every visitor takes.

⚡ POWER TIP
Taking a day trip to Isla Saona? There is no signal at all there from Claro, Altice, or anyone else — it is a protected nature reserve with zero towers. Download anything you need offline before the boat leaves, and let people know you will be unreachable for the day.
✅ VPN FULLY LEGAL
No restrictions on personal VPN use in the Dominican Republic. Use one freely on public WiFi, in hotels, or anywhere else — it is simply good practice, not a legal grey area. See our travel security note below.

// Network operators
Claro
The largest network by a clear margin, covering 98% of tourist zones and offering the strongest rural and peninsula reach of any Dominican carrier. Most travel eSIM providers route through Claro for this reason.
Altice
The strong second option, covering 95% of tourist zones with excellent performance in Santo Domingo, Santiago, and Punta Cana. Slightly weaker than Claro once you head into rural areas.
// Coverage by area
Punta Cana, Santo Domingo & Santiago
Coverage is excellent across every major tourist zone — Punta Cana, Bávaro, the Colonial Zone in Santo Domingo, Santiago, Puerto Plata, and Samaná all get strong 4G, with 5G now live in the three biggest cities.
The Bahoruco mountains & Haiti border
Away from the tourist corridor, coverage from all three networks drops to roughly 60–70% in mountainous areas like the Sierra de Bahoruco and near the Haitian border. Still generally usable, just less consistent than the coast.
💡 The one real exception: Isla Saona
Despite being one of the most popular day-trip excursions from Punta Cana and Bayahibe, Isla Saona is a protected nature reserve with no cell towers and no signal from any operator. It is not a coverage gap you can work around — genuinely plan to be offline for the day.
// Practical tips
A dedicated tourist police hotline
Beyond the standard emergency line, CESTUR (tourist police) has its own number: 809-200-3500, for theft, scams, or tour operator disputes. Worth saving separately from 911 for non-emergency issues.
One number for everything
The Dominican Republic runs a nationwide unified 911 system, expanded since 2014 to cover police, fire, and ambulance from a single call, free from any phone including mobiles with no active plan. Multilingual operators handle English and Spanish.
Airport SIM registration takes 30–60 minutes
Buying a physical Claro or Altice SIM at Punta Cana or Santo Domingo airport means passport ID and a real time cost — often half an hour or more after a long flight. eSIM tourist plans skip this entirely.
// Travel security
Protect your identity abroad
Hotel and resort WiFi in the Dominican Republic carries the same everyday risk as anywhere else. Avoid logging into banking or sensitive accounts on public networks. Use your eSIM data instead where you can — and since VPNs are unrestricted here, running one on public WiFi is genuinely worth doing.
Alternative ID for travel
When signing up to local apps and services — convenience store WiFi portals, rail booking sites, loyalty apps — consider using a disposable identity and email address to keep your real details private. Surfshark Alternative ID is built for exactly this use case.
