How to Get a Dominican SIM Card and Cell Phone Plan as a Foreigner: Claro, Altice, and Viva Compared

Getting connected in the Dominican Republic is one of the first practical tasks you'll tackle after landing, and thankfully it's one of the easier ones. Whether you're here on a tourist stamp scouting for a move, settling in as a new resident, or working remotely from a beach town, a local SIM will save you money, unlock better data speeds, and let you actually call a plumber, a landlord, or a delivery driver without WhatsApp being your only lifeline.

This guide walks you through the three carriers foreigners use — Claro, Altice, and Viva — how to buy a SIM as a non-resident, how prepaid ("prepago") and postpaid ("pospago") plans compare, and the small tricks that make daily life smoother.

The three carriers at a glance

The Dominican mobile market is dominated by three operators, all of which run modern 4G LTE networks and are rolling out 5G coverage in major cities.

• Claro — The largest carrier and part of the América Móvil group. Widely considered to have the best nationwide coverage, especially in rural areas, the interior, and along highways. If you plan to travel outside Santo Domingo, Santiago, and the tourist corridors, Claro is the safest default.
• Altice — The second-largest operator, strong in urban areas (Santo Domingo, Santiago, Punta Cana, Puerto Plata) and often the most aggressive on data promotions. Also a major home-internet and TV provider, so bundling is easy if you rent long-term.
• Viva — The smallest of the three but often the cheapest, with competitive data packages and decent urban coverage. Coverage thins out in remote areas, so it's better as a secondary or budget line.

There's no single "best" — many long-term expats keep two lines (one Claro for coverage, one Altice or Viva for price) in a dual-SIM phone.

What you need to buy a SIM as a foreigner

Dominican regulations require carriers to register every SIM to an identified person. As a foreigner, you can absolutely buy one — you just need to bring the right documents.

At a minimum, bring:

• Your passport (original, not a photocopy). If you have a Dominican cédula as a resident, bring that too — it makes the process faster.
• A local address (your Airbnb, hotel, or rental will do). The clerk will type it into the registration form.
• Cash in pesos or a card. SIMs themselves are inexpensive; you'll pay more for the recharge than the physical SIM.

Buy your SIM at an official carrier store ("tienda" or "centro de atención") rather than a street kiosk or corner colmado. Official stores handle the registration properly, activate the line on the spot, and can sell you a data package immediately. You'll find flagship stores in every major mall — Ágora, Sambil, Blue Mall, Galería 360 in Santo Domingo; Sambil Santiago; Downtown Punta Cana; and Playa Dorada plaza in Puerto Plata. Airport kiosks exist but tend to be pricier and less flexible.

Expect the whole process to take 15–30 minutes. The clerk photographs your passport, registers the SIM in your name, hands you the new number, and helps you top up.

Prepaid vs. postpaid: which should you pick?

Prepaid ("prepago")

This is what most newcomers and short-term visitors use. You pay up front for a bundle of minutes, texts, and data that lasts a set number of days (typically 7, 15, or 30). No contract, no credit check, no Dominican bank account required. When it expires, you recharge — through the carrier's app, at any colmado or pharmacy showing the carrier's logo, at a Western Union counter, or online with a foreign credit card.

Prepaid is the right choice if you:

• Are still on a tourist stamp or in your first months as a resident.
• Don't yet have a Dominican bank account or cédula.
• Want to test coverage in your neighborhood before committing.
• Travel back and forth and don't need the line active year-round.

Postpaid ("pospago")

Monthly billing, usually more data per peso, and often includes perks like international roaming minutes or streaming subscriptions. The catch: carriers generally want a cédula (so, legal residency), sometimes proof of income or a Dominican bank account for autopay, and a signed contract in Spanish. Some carriers will accept a passport plus a Dominican co-signer or a large deposit, but policies vary by branch and by the mood of the manager.

Postpaid makes sense once you:

• Have your cédula.
• Plan to stay at least a year.
• Want to bundle mobile with home internet or TV (especially with Altice).

Realistic costs and what to expect

Prices shift with promotions, so treat any figure you read online — including this one — as a ballpark. In broad terms, a basic prepaid monthly bundle with several gigabytes of data plus unlimited WhatsApp and social apps runs in the low thousands of pesos. Heavier data plans, or postpaid with unlimited calling, cost more. All three carriers publish current prices on their websites and apps (Mi Claro, Mi Altice, and Viva App) — check there for today's offers before you walk into a store, and confirm the final price with the clerk.

A few things worth knowing:

• "Unlimited social" bundles are common and genuinely useful — WhatsApp, Instagram, TikTok, and Facebook don't count against your data cap.
• WhatsApp is the national nervous system. Businesses, doctors, landlords, and government offices communicate by WhatsApp far more than by email. Make sure your number works with it from day one.
• Data speeds are good in cities and tourist zones and adequate in most towns. Rural mountain areas and remote beaches can drop to slow 4G or 3G.
• International calling to the US and Canada is often included or very cheap because the DR shares the North American numbering plan (+1 809, +1 829, +1 849).

eSIM and keeping your foreign number

All three carriers now support eSIM on compatible phones, which lets you activate a Dominican line without swapping out your home-country SIM. This is ideal if you want to keep your US, Canadian, or European number active for banking two-factor codes while using the local line for daily use. Ask specifically for an "eSIM" at the store; not every branch or clerk is equally comfortable with the activation, so it may take a few extra minutes.

If your phone is older or single-SIM, consider a cheap dual-SIM Android handset (widely available locally for the equivalent of a nice dinner out) as a dedicated Dominican line.

Unlocking, compatibility, and common mistakes

• Make sure your phone is unlocked before you arrive. Carrier-locked phones from the US or Canada will not accept a Dominican SIM.
• All three carriers use standard GSM/LTE bands that work with virtually every unlocked international phone.
• Don't buy from street vendors. SIMs sold outside official channels may be pre-registered to someone else, which creates headaches if the line gets flagged.
• Save your PUK code and the receipt with your assigned phone number. You'll need them if the SIM locks or you lose the phone.
• Register the SIM in your own name. Some short-term visitors let a friend or landlord register it "to save time." Don't — you'll lose access if the relationship sours, and it complicates recovery.

Quick FAQ

Can I keep my Dominican number if I switch carriers? Yes — number portability exists in the DR. You can port your number between Claro, Altice, and Viva by requesting it at the new carrier's store.

Do I need to be a resident to buy a SIM? No. A tourist with a valid passport can buy a prepaid SIM. Postpaid contracts generally require residency and a cédula.

Will my US or European carrier's roaming work here? Yes, but it's usually expensive. A local prepaid SIM or eSIM almost always pays for itself within a week.

How do I recharge? Through the carrier's app with a card, online, at any colmado or pharmacy showing the carrier's decal, or at supermarket cashiers. Ask for a "recarga" and give your number.

Which carrier has the best coverage where I'm moving? Ask neighbors before you commit. Coverage genuinely varies block by block, especially in mountain towns and remote coastal areas.

Carrier pricing, promotions, and registration requirements change frequently — always confirm today's plans and documentation rules directly with Claro, Altice, or Viva before you sign anything or hand over cash.
