Claro is the local SIM most visitors should pick in the Dominican Republic, with the broadest coverage for excursions and a prepaid SIM at around 150 DOP (about 2 USD) plus cheap tourist data packs; Altice is a strong city-and-resort alternative with generous unlimited day passes. That said, a travel eSIM skips the passport registration and the airport stall, and connects you the moment you land, so check our Dominican Republic eSIM guide to compare, or let the eSIM Finder match a plan to your trip.

The Dominican Mobile Landscape
The Dominican Republic runs on three mobile networks: Claro, Altice, and Viva. Claro is the heavyweight, with the largest subscriber base and by far the most complete reach across the island, including the resort corridors, the highways between cities, and the smaller coastal towns where Altice and Viva start to fade. Altice, which absorbed the old Orange and Tricom brands, is the polished number two and genuinely strong in Santo Domingo, Punta Cana, and the bigger towns. Viva is the budget third operator and best treated as a city-only option.
For a vacationer the headline is that data is cheap once you are on a real local plan. A Claro tourist data pack runs only a few dollars, and Altice sells unlimited day passes for the price of a coffee. The catches are that every prepaid SIM must be registered to your passport, that your phone has to be carrier-unlocked, and that the SIM vendors near the airports charge tourist prices, so where and how you buy matters as much as which logo is on the card.
Passport Registration Is Required
Dominican rules require every prepaid SIM to be registered to your passport at the point of sale. Official Claro and Altice stores, airport counters, and large retailers will scan your document and activate the line for you on the spot. Bring the physical passport, not a photo, and make sure your phone is unlocked before you travel, since a locked handset will reject a Dominican SIM no matter where you buy it.
Claro
Claro: The Nationwide Standard
The country's largest carrier with the widest coverage for excursions and road trips
Claro is the default for nearly every traveler because it is the network that keeps a signal where the others give up: the road north to Macao Beach, the docks at Bayahibe, the highway across to Santo Domingo, and the smaller towns inland. Tourist data packs are inexpensive, so a 5 GB or 8 GB pack costing the equivalent of a few dollars covers maps and messaging through a busy excursion day, and you can stack recharges through the Mi Claro app as you go.
Buy the SIM at a proper Claro store or branded airport counter rather than an unmarked kiosk, and the staff will register it to your passport and set up the data pack correctly. That single step gets you the real plan at the real price and avoids the most common Dominican SIM headaches.

Altice
Altice: Strong in the Cities and Resorts
The polished number two with generous unlimited day passes and a free SIM
Altice is a great pick if your trip centers on the resort zone and the bigger towns. Its short unlimited day passes are remarkable value, costing barely a dollar or two for a full day of data, which suits a guest who only wants mobile data on the days they head out on an excursion or into Santo Domingo. The tourist bundle, roughly 15 GB with unlimited calls and texts plus some credit for around 550 DOP, is a tidy single purchase for a full beach week.
The one thing to keep in mind is reach. Altice is dependable across Punta Cana, Bavaro, and the capital, but it thins out earlier than Claro on the rural coastal tracks and remote beaches, so if your plans lean heavily on off-the-beaten-path excursions, Claro is the safer card.
Strengths
Weaknesses
Viva
Viva: The Budget City Option
The smallest of the three, fine around the cities but limited elsewhere
Viva rounds out the trio. Inside Santo Domingo and Santiago the service is perfectly usable, but its footprint is the weakest of the three once you move toward the eastern resorts, the excursion routes, and the smaller coastal towns. For a Punta Cana vacation it is rarely the right choice, and the price edge over Altice is too small to justify the patchier coverage. Treat it as a backup carrier rather than your main travel SIM.
Dominican Republic SIM Plans Compared
| Carrier | Typical Plan | Validity | Price (store) | Best For |
|---|---|---|---|---|
| Claro Data Pack | 8 GB | 5 days | ~170 DOP (about 3 USD) + 150 DOP SIM | Excursions and all-round coverage |
| Claro Data Pack | 5 GB | 5 days | ~145 DOP (about 2.60 USD) + SIM | Budget nationwide coverage |
| Altice Day Pass | Unlimited / day | 1 to 5 days | ~49 to 139 DOP (1 to 2 USD) | Occasional data on excursion days |
| Altice Tourist Bundle | ~15 GB + calls/texts | ~30 days | ~550 DOP (about 10 USD) | A full resort week in one buy |
Prices above are typical official-store rates. Vendors clustered near the airport arrivals halls tend to run higher and sometimes bundle a data pack you did not ask for, so the table is your sanity check before you hand over cash. Adding the one-time SIM cost, a full week of Claro data still lands in the low single digits of US dollars.
Where to Buy a SIM Card in the Dominican Republic
Official Claro and Altice Stores (Best Value)
Both carriers run branded shops in Santo Domingo, Santiago, La Romana, and around Downtown Punta Cana. This is the cheapest and safest route: staff scan your passport, register the line, and load the data pack at the listed price. Look for the Claro and Altice stores in the Punta Cana and Bavaro commercial plazas a short ride from the resorts.
Airport Arrival Counters
You will find carrier stores in the arrivals area at Las Americas (Santo Domingo) and vendors near the open-air halls at Punta Cana (PUJ). Handy if you want data before your transfer, but expect to pay more than in a city store. Stick to the branded counters rather than the loose stalls, and confirm the exact pack and price before you pay.
Supermarkets and Pharmacies
Large chains and pharmacies around Bavaro and Santo Domingo sell SIMs and recharge vouchers. Coverage of the registration step varies, so a carrier store is still the smoother option, but these are a reasonable fallback for a top-up once your line is already set up.
Test Before You Leave the Counter
Wherever you buy, slot the SIM in and confirm data works on the spot. Load a map or a webpage, check that the pack and validity match what you paid for, and keep the receipt. Doing this at the counter defeats almost every overcharge or wrong-pack mix-up.
eSIM vs Local SIM in the Dominican Republic
| Factor | eSIM | Local SIM |
|---|---|---|
| Setup time | 3 minutes (before your flight) | 10 to 20 minutes at a store with passport |
| Passport registration | Not needed | Required by law, done in person |
| Price (week of data) | ~5 to 12 USD (Airalo, Nomad, Holafly) | ~3 to 10 USD (often with calls and texts) |
| Coverage | Pick a plan that lists Claro for excursions | Buy Claro directly for the widest reach |
| Best for | Most vacationers, no stalls or registration | Long stays or anyone needing a local number |
Local SIMs are genuinely cheap here, but the passport registration, the unlocked-phone requirement, and the inflated airport vendors make them more fiddly than the rock-bottom prices suggest. For most short-stay vacationers who just want data, a travel eSIM is the simpler path: install it before you fly and you are online the second you land, no stall, no scan, no haggling. If you want a Dominican number for calling resorts, drivers, or tour operators, a local Claro SIM is still worth the extra effort.
Dominican-Specific Tips
Practical Advice for Staying Connected in the Dominican Republic
Take Claro for the excursions: For the road to Macao Beach, the Bayahibe docks for Saona, and the drive to Santo Domingo, Claro is the network with the most consistent signal. Expect the odd dead patch mid-channel on boat trips even on Claro, with service returning near the coast.
Unlock your phone before you fly: A Dominican prepaid SIM only works in a carrier-unlocked handset. Check with your home provider before the trip, because there is no fix for a locked phone once you land.
Carry the physical passport: Registration is mandatory and handled at purchase. A photo is usually not accepted, so bring the real document when you go to buy.
Recharge through the app: Mi Claro and the Altice app let you top up data packs with a card, which is easier than hunting for a voucher once your line is set up.
Lean on resort WiFi for the big stuff: Hotels offer free WiFi for downloads and calls back at the room, so your data mainly covers maps, ride bookings, and uploads while you are out and about.
Frequently Asked Questions
Do I need my passport to buy a SIM card in the Dominican Republic?
Yes. Local rules require every prepaid SIM to be registered to your passport at purchase. Official Claro and Altice stores, airport counters, and larger retailers will scan the document and activate the line for you. Carry the physical passport rather than a photo, and make sure your phone is carrier-unlocked, since a locked handset will not accept a Dominican SIM. A travel eSIM avoids the registration step entirely.
Which carrier has the best coverage for Punta Cana excursions?
Claro. It has the widest footprint on the island and the most reliable signal on the routes excursions follow, from the coastal road to Macao Beach to the Bayahibe docks for Saona Island and the highway to Santo Domingo. Altice is excellent in the resort zone and the cities but fades sooner on rural tracks and remote beaches, and Viva is weaker still. For an excursion-heavy trip, choose Claro or an eSIM that lists Claro as its network.
How much does a tourist SIM cost in the Dominican Republic?
Very little. A Claro SIM is around 150 DOP (about 2 USD), and a 5 GB five-day data pack adds roughly 145 DOP, so a week of data lands in the low single digits of US dollars. Altice gives away the SIM with a recharge and sells unlimited day passes from about 49 to 139 DOP, plus a roughly 15 GB tourist bundle near 550 DOP. Buy from a carrier store rather than an airport stall to get those listed prices.
Can I just use the free WiFi at my all-inclusive instead of a SIM?
You can, but it has limits. Resort WiFi is shared among hundreds of guests, so it slows in the evenings and often reaches only the lobby and pool areas rather than your room or the beach. It is fine for big downloads and calls back at the room, but a local SIM or eSIM gives you your own connection for maps and bookings on excursions, where there is no resort WiFi at all. Many travelers use both together.
Should I get an eSIM or a local SIM for the Dominican Republic?
For most vacationers, an eSIM is easier. It installs in minutes before you fly, works the instant you land, and skips both the passport registration and the unlocked-phone requirement of a local card. Local SIMs edge ahead on price and give you a Dominican number for calling resorts and tour operators, which helps on a longer stay. If you go local, buy Claro from an official store for the widest coverage and a fair price.
