Bottom line: a Dominican prepaid line now carries an identity requirement that visitors are not warned about. Under INDOTEL Resolución 064-2025, tightened by Resolución 073-2025, every active prepaid line had to be tied to a verified holder — cédula, passport or residence card — with a final deadline of 28 September 2025 for Claro customers and 29 September for Altice; unvalidated lines are suspended for up to two months and then cancelled outright. A travel eSIM bought before you fly is not a Dominican line: it attaches as inbound roaming, so nothing to validate and nobody’s counter to visit. On speed, MedUX measured Claro at 46.84 Mbps average download nationwide in June 2026, Altice at 29.52 and Viva at 15.23 across 41,162 samples. And the market is about to change: on 19 August 2026 INDOTEL awarded Viettel 240 MHz of spectrum for a 20-year concession, putting a fourth mobile operator into the country.

This page was rewritten from scratch in August 2026 against primary sources: the Dominican telecom regulator’s own resolutions and press releases, the immigration authority, the operators’ published terms, and independent field measurement. Every number below is dated, because most of the ones circulating online are from before the prepaid clean-up.

What changed: the prepaid identity purge of 2025

For years a Dominican prepaid SIM was among the easiest in the Caribbean to obtain. That ended on 29 June 2025, when the Consejo Directivo of the Instituto Dominicano de las Telecomunicaciones (INDOTEL) issued Resolución núm. 064-2025, giving mobile operators 30 days to validate and purge the identity of every user holding an active prepaid line. The stated purpose was to let investigators trace the holder of calls or messages linked to crimes.

The resolution set out the mechanics, and they matter to anyone buying a local line:

• Identification is by official document. The text names cédula, pasaporte o carnet de residencia — so a foreign passport is expressly accepted, and expressly required.
• Operators must store the data securely and notify customers by SMS or other means of the procedure and the deadline.
• Non-compliance has teeth. An unvalidated line is suspended for up to two months, then cancelled. The number is gone.

Operators and the industry association Comtec asked for reconsideration. INDOTEL granted more time through Resolución 073-2025, and the extended window closed at the end of September 2025 — 28 September for Claro subscribers, 29 September for Altice. Dominican press reporting at the deadline put the number of prepaid lines still needing validation at more than eight million, on a population of roughly eleven million. That is the scale of what was cleaned out of the registry.

Why a travel eSIM sits outside all of this

The resolutions bind Dominican concessionaires and the lines they issue. An eSIM profile you download from an international travel-data provider before departure is issued outside the country. On landing, your handset attaches to Claro, Altice or Viva as an inbound roamer under the home operator’s identity. There is no Dominican line, so there is no entry in the Dominican registry, no validation deadline, and no store visit.

That is a real difference in 2026, but it is a trade-off rather than a verdict. Read the table as a decision rule:

Network reality: measured numbers, not marketing

Three mobile networks serve the country today: Claro (América Móvil), Altice Dominicana and Viva. Whatever brand is printed on your eSIM, your phone is talking to one of those three radio networks — so their measured performance is your performance.

The independent measurement firm MedUX publishes a country report built from SDK-based tests on real handsets. Its Dominican Republic Mobile QoE report for June 2026 is based on 41,162 samples taken nationwide across 3G, 4G and 5G, at a 95% confidence interval:

Two things worth noticing, because they are not what the marketing says. Claro leads on download by a wide margin — roughly 1.6× Altice and 3× Viva. But Altice wins on upload, by about 43% over Claro. If your trip involves sending video, backing up photos over mobile, or joining calls from a rented villa without fibre, upload is the number that decides your experience, and the ranking flips. If you are mainly streaming, navigating and messaging, Claro’s download lead is the one that counts.

Coverage and speed are not the same thing either. These are country-wide averages that mix Santo Domingo with the Cordillera Central and the Samaná peninsula. Expect the resort corridors — Punta Cana, Bávaro, Puerto Plata, Bayahíbe — to sit well above these averages and the mountain interior to sit well below.

A fourth operator is coming: the August 2026 spectrum award

This is the item that will date every other eSIM guide to the country. On 19 August 2026 INDOTEL’s Consejo Directivo announced the results of tender INDOTEL/LPI-001-2026, adopted unanimously as Resolución núm. 73-2026:

• Viettel — the Vietnamese operator — won 240 MHz on a 20-year concession: 40 MHz at 700 MHz, 100 MHz at 2.3 GHz and 100 MHz at 3.6 GHz. It must incorporate a Dominican company to hold the licence.
• Claro Dominicana took 20 MHz at 700 MHz for the 15 years remaining on its existing concession.
• The 30 MHz offered in the AWS band drew no bids and was declared deserted.
• Winners must sign the concession contract or addendum within 90 days, and up to 30% of the payment may be made by executing INDOTEL development projects.

What this means practically: 700 MHz is the long-range coverage layer that reaches inside buildings and across rural terrain, and 3.6 GHz is the capacity layer 5G needs. A newcomer holding 100 MHz at 3.6 GHz has more contiguous 5G capacity than the incumbents deploy today. Nothing changes for a trip taken this year — network build-out takes years, and the concession contract is still to be signed — but if you travel to the Dominican Republic regularly, the competitive picture from 2027 onward is not the one described in the guides currently ranking for this topic. INDOTEL separately presented a draft General Telecommunications, Digital Infrastructure and Connectivity Law on 14 August 2026 to replace Ley 153-98, with a single-concession regime and stronger user-protection rules.

Devices, bands and eSIM support

Dominican LTE runs mainly on band 4 (AWS 1700/2100), band 2 (1900) and band 5 (850), with 700 MHz now being layered in following the August 2026 award. 5G is concentrated on mid-band in Santo Domingo, Santiago and the eastern tourist corridor.

• Phones sold in North America cover bands 2/4/5 as standard — no issue.
• Phones sold in Japan, Korea or parts of Europe sometimes omit band 4, which is the workhorse layer here. You will still connect, but on weaker bands. Check the model’s band list before you depend on it.
• The handset must be carrier-unlocked and eSIM-capable. Claro publishes its own supported-device list for eSIM, which currently runs from iPhone XS and Galaxy S20 forward through iPhone 17, iPhone Air and Galaxy S25 — a useful proxy for what works on Dominican networks generally.
• Install the profile before you leave home. Downloading an eSIM needs an internet connection; airport Wi-Fi at Punta Cana and Las Américas works, but it is not something to depend on with luggage in hand. Note also that as of 2026 there is no SIM retail counter in the Punta Cana arrivals area, which is where most visitors land.

The provisioning standard your phone implements is the GSMA’s consumer remote SIM provisioning specification; the GSMA maintains the specification and the device list.

Entry formalities that assume you have a phone

The Dominican Republic replaced its paper arrival and departure forms with a single digital E-Ticket in April 2021, administered by the Dirección General de Migración. It is free, mandatory for both entry and exit, and it produces a QR code the airline checks at the counter.

• The old “72 hours before travel” rule no longer applies. You can file it as soon as you have flight details. What matters is having it before you reach the airline desk.
• Save the QR code offline — screenshot or PDF. The arrivals hall is exactly where mobile data is most congested, and it is the one moment you cannot afford a spinning loader.
• You need a second E-Ticket for departure. Travellers routinely forget this and fill it in standing at the check-in desk. That, too, is easier on a working data connection.

A checklist that reflects the 2026 rules

1. Decide whether you need a Dominican number or only data. That single question settles everything else on this page.
2. Data only: buy and install the eSIM profile at home, leave it switched off, enable it after landing. No validation, no queue, no passport copy in a third party’s file.
3. Need a local number: bring your passport, buy in Santo Domingo rather than at Punta Cana arrivals, and expect the identity check at the counter — it is now a legal obligation on the operator, not a formality it can waive.
4. Choose the network for the job: Claro if you are downloading and streaming, Altice if you are uploading video or joining calls.
5. Turn off data roaming on your home profile before you fly, so the eSIM carries the traffic and your home carrier does not.
6. File both E-Tickets — arrival and departure — and keep both QR codes offline.
7. If you are combining the trip with other stops, the rules differ more than people expect. We keep country pages for Mexico, the United States and Canada, and the eSIM basics guide covers the setup steps common to every destination.

FAQ

Do I have to register a travel eSIM with the Dominican authorities?

No, if the eSIM was issued outside the country. INDOTEL’s Resoluciones 064-2025 and 073-2025 apply to lines issued by Dominican concessionaires. A foreign-issued travel eSIM attaches as inbound roaming under its home operator’s identity, so it is not a Dominican line and does not appear in the Dominican registry.

What do I need to buy a local Claro or Altice prepaid line as a visitor?

Your passport, in person. Resolución 064-2025 requires the operator to identify each user with an official document — cédula, passport or residence card — and to store that data. Since the 2025 purge, operators apply this at the point of sale rather than treating it as optional paperwork.

What happens to a prepaid line that was never validated?

It is suspended for up to two months and then permanently cancelled, and the number is released. The deadline ran to 28 September 2025 for Claro and 29 September for Altice. If you kept a Dominican SIM from an earlier trip and left it dormant through 2025, assume the number is gone and check before you rely on it.

Which network is fastest in the Dominican Republic?

It depends on direction. MedUX’s June 2026 measurements put Claro first on download at 46.84 Mb/s against Altice’s 29.52 and Viva’s 15.23, but Altice first on upload at 14.79 Mb/s against Claro’s 10.31. Download matters for streaming and maps; upload matters for video calls and photo backup.

Will Viettel’s arrival change anything for my trip?

Not this year. The award was announced on 19 August 2026, the concession contract has a 90-day signing window, and Viettel must first incorporate a Dominican company. Building out 240 MHz across 700 MHz, 2.3 GHz and 3.6 GHz takes years. It matters if you visit regularly: a fourth network with that much mid-band spectrum is the first genuine competitive pressure on Claro in a long time.

Can I buy a SIM card at Punta Cana airport?

As of 2026 there is no operator retail counter in the Punta Cana arrivals area, which is where most visitors to the eastern resorts land. Las Américas in Santo Domingo does have Claro and Altice stores. If you are flying into Punta Cana and want connectivity from the moment you switch your phone on, an eSIM installed before departure avoids the problem entirely.

Do I still need to fill in the E-Ticket 72 hours before travel?

No. The 72-hour window was dropped; the E-Ticket can be completed as soon as you have flight details, and what matters is presenting it at the airline counter. It remains mandatory, it is free, and you need one for arrival and a second for departure.

Can I keep my home number while using a Dominican eSIM?

Yes, on any dual-SIM handset. Keep the home profile active for SMS and calls with data roaming switched off, and set the eSIM as the data line. This is the standard way to keep receiving bank one-time passwords without paying roaming rates.
