In popular destinations like Las Terrenas, Santo Domingo, Punta Cana, and Cabarete, digital connectivity has improved significantly in recent years. Most hotels, vacation rentals, and restaurants offer Wi-Fi, while mobile networks cover much of the country, even in some surprisingly remote areas. That said, knowing how to access fast, affordable, and secure connections can save you time and hassle.

In this guide, we’ll walk you through everything you need to know about Wi-Fi availability, choosing a SIM card, and using mobile data in the Dominican Republic. With the right information, you’ll be able to stay connected with confidence throughout your stay.

Wi-Fi Availability in the Dominican Republic

Staying connected via Wi-Fi is relatively easy in the Dominican Republic, especially in tourist areas. However, quality, speed, and accessibility vary depending on the type of establishment and location. The table below provides a comprehensive breakdown of what travelers can expect.

Mobile Internet in the Dominican Republic

For travelers who need flexible, on-the-go connectivity, mobile internet in the Dominican Republic is generally reliable, especially in cities and tourist zones. With local SIM cards, prepaid data, and eSIM options, it is easy to get online without depending solely on Wi-Fi.

Overview of Mobile Networks

The three main mobile providers in the Dominican Republic are Claro, Altice, and Viva. Claro offers the most extensive network coverage, making it the best choice for travelers moving across different regions, including rural and coastal areas. Altice has good coverage in cities and major tourist towns like Santo Domingo, Punta Cana, and Santiago, and is known for competitive pricing. Viva is a smaller, budget-friendly provider with limited rural coverage.

In general, 4G LTE service is widely available in populated areas, with average download speeds between 10 to 30 Mbps. Remote areas may still rely on 3G or slower connections. In towns like Las Terrenas or Cabarete, where digital nomads and expats are common, Claro usually delivers the most stable signal. It’s a good idea to check the provider’s coverage map online or ask locals before purchasing a SIM card, especially if you’re heading to less developed areas.

Tip: If you’re staying in a mountainous or coastal village, always test coverage with a local’s phone before choosing a provider.

Best SIM Cards for Tourists

Tourists visiting the Dominican Republic can choose from prepaid SIM options designed for short-term stays. Claro is the most popular choice due to its strong coverage and dependable service. Altice also offers tourist-friendly packages and may be a more economical option if you plan to use a lot of data.

A basic Claro tourist SIM usually costs around $10 to USD 20 and includes 5 to 10 GB of data, with local call minutes valid for 15 to 30 days. Altice offers similar packages and sometimes adds unlimited access to apps like WhatsApp or Facebook as part of the deal.

You can purchase SIM cards at airport kiosks (especially at SDQ, PUJ, and STI), official stores in shopping malls, or even in supermarkets. Airport vendors are convenient but often slightly more expensive.

Tip: If you want to save money, wait until you’re in town to visit an official Claro or Altice store for better prices and more plan options.

How to Get a SIM Card?

Buying a SIM card in the Dominican Republic is straightforward. You will need to present your passport, as all mobile numbers must be registered under your name. The process typically involves a quick ID scan and takes less than 15 minutes.

In larger cities and airports, customer service representatives often speak some English. However, in smaller towns and local stores, communication is usually in Spanish.

Example phrase: “Quiero comprar una SIM con internet por una semana” means “I want to buy a SIM with internet for one week.”

Tip: Take a screenshot of your phone settings showing your IMEI number, in case staff need it for registration.

Data Plans and Top-Up Options

Prepaid data plans in the Dominican Republic are affordable and flexible. You can choose from daily, weekly, or monthly data packages depending on your needs. For example, a one-day package with 1 GB of data might cost RD$50 (less than USD 1), while a 7-day plan with 5 GB could cost around RD$250 (USD 4.25).

Top-ups can be done in several ways. Most colmados (local mini-markets), pharmacies, and supermarkets sell recharge codes. Alternatively, you can use the provider’s mobile app or online platforms like Recarga.com or MobileRecharge. Apps are also useful for checking your remaining data balance and plan expiry.

Tip: To top up quickly, ask at any colmado: “Puedo recargar mi Claro, por favor?” (“Can I recharge my Claro, please?”). They’ll just ask for your phone number.

eSIM Options (for eSIM-Compatible Phones)

eSIM technology is growing in popularity, and the Dominican Republic is slowly catching up. Claro offers limited eSIM support in its flagship stores, though availability can vary. International providers like Airalo, Holafly, and Nomad offer tourist eSIMs you can activate before or upon arrival.

eSIMs are ideal for travelers who want a hassle-free setup. You simply scan a QR code to activate your data plan and can still use your home SIM for calls and texts if your phone supports dual SIM. They are especially convenient for short stays or when arriving outside of store hours.

However, eSIMs tend to be more expensive than local physical SIM cards and lack in-person customer support in case of technical issues. They’re best suited for tech-savvy travelers or those on tight schedules.

Tip: If you’re arriving late at night or during a national holiday when stores are closed, installing an eSIM in advance can keep you connected from the moment you land.

What to Expect from Internet Speed and Reliability?

Internet quality in the Dominican Republic has improved significantly, especially in areas with a strong tourism or expat presence. However, travelers should be aware of regional differences in speed, occasional service interruptions, and how to prepare for them.

Average Speeds in Urban vs. Rural Areas

• Urban Areas (Santo Domingo, Santiago, Punta Cana):
  • Average download speeds range from 20 to 100 Mbps, depending on the provider and infrastructure.
  • Fiber-optic internet is common in newer buildings and residential neighborhoods.
  • 4G LTE mobile coverage is consistent, making tethering or hotspot use a reliable option.

• Rural Areas (mountains, small villages, remote beaches):
  • Expect lower speeds between 1 to 10 Mbps, with occasional dropouts.
  • 3G is still in use in many remote locations.
  • Some areas rely on satellite connections or wireless repeaters, which may be unstable during storms or high network usage.

Flyhack: When booking an Airbnb or rental, ask the host to send a screenshot of their speed test result from speedtest.net. This is more reliable than a vague “Wi-Fi available” listing.

Best Regions for Digital Nomads

Some locations in the Dominican Republic have developed strong infrastructure for remote work and digital nomad lifestyles. These areas typically have high-speed internet, coworking spaces, and a supportive expat community.

• Las Terrenas (Samaná Peninsula):
  • Popular with digital nomads, with fiber internet available in many rentals.
  • Coworking spaces like CoWorking Las Terrenas offer speeds over 50 Mbps and power backup.

• Cabarete (North Coast):
  • Surf and kitesurf hub with a growing remote work scene.
  • Cafes and coworking spaces provide stable internet and a social work-friendly environment.

• Santo Domingo and Santiago:
  • Best access to consistent high-speed fiber internet.
  • Corporate coworking chains and cafes with AC and power outlets are widely available.

Tip: Choose rentals that specifically mention “fibra óptica” (fiber optic) in their amenities, and confirm the connection type directly with the host before arrival.

Peak Time Congestion and Power Outages

• Peak Internet Hours:
  • Between 6 PM and 10 PM, networks can slow down due to high traffic from local users.
  • This is especially noticeable on mobile data networks in apartment complexes or rural areas.

• Power Outages:
  • Known locally as “apagones,” outages can affect Wi-Fi routers unless a power inverter or generator is present.
  • Rural areas may experience brief daily blackouts or infrastructure issues after heavy rain.

Tips to stay connected during interruptions:

• Always keep your phone charged and a data plan active as a backup to Wi-Fi.
• Consider carrying a portable power bank or mobile hotspot device if you plan to work during travel.
• Ask your accommodation if they have a “planta” (generator) or an inverter to keep the internet running during outages.

Flyhack: If the internet is mission-critical (for remote work or meetings), rent in areas where Claro offers fiber service and look for accommodations with battery backup (inverter) included. Add a local SIM with hotspot capability as a failover.

Staying Connected During Excursions and Remote Travel

While the Dominican Republic has decent coverage in populated areas, many of its most beautiful attractions, secluded beaches, waterfalls, and mountain trails, are far from strong Wi-Fi signals or mobile towers. If you plan to explore off-the-grid locations, it’s important to prepare in advance to avoid getting stuck without communication, navigation, or access to essential info.

Tips for Off-the-Grid Locations (Beaches, Mountains)

• Research mobile coverage before you go.
  • Use online coverage maps from Claro and Altice to check signal strength in rural areas.
  • Popular but remote spots like Playa Frontón (Las Galeras), Playa Rincón, or El Limón waterfall often have little to no signal.

• Let someone know your location if venturing far from towns.
  • Especially when hiking or heading to undeveloped beaches, share your plan with your host or a contact.

• Download everything you’ll need in advance.
  • This includes directions, offline maps, and translator apps.
  • Save hotel/host contacts and important info as screenshots in case the signal is lost.

Tip: In Samaná and mountainous areas around Jarabacoa, the signal can drop without warning. Make sure to switch your phone to low power mode to conserve battery while off-grid.

Portable Hotspots (MiFi) and Travel Routers

• MiFi devices allow you to create your own mobile Wi-Fi zone using a local SIM card. These are ideal for group travel or working from your laptop on the go.
  • Most work with prepaid Dominican SIMs from Claro or Altice.
  • Useful for day trips or car travel when tethering from your phone drains battery too quickly.

• Travel routers can be used to boost weak hotel or café Wi-Fi signals or to convert a wired Ethernet connection into a wireless one.
  • Recommended brands include TP-Link and GL.iNet.
  • Some models include built-in VPN functionality for added security.

Tip: If you’re traveling as a family or a remote working couple, a portable hotspot is more efficient than multiple devices tethering to a single phone.

Offline Map Apps and Download Recommendations

• Google Maps
  • Before leaving Wi-Fi, zoom into your area and tap “Download offline map.” It will store routes, landmarks, and directions for use without a signal.

• Maps.me
  • Great for hiking and rural areas, this app offers downloadable topographic maps and trail guides.
  • Includes points of interest like water sources and lookout points.

• Organic Maps
  • A privacy-focused alternative to Maps.me with similar offline functionality and no background tracking.

• Google Translate
  • Download the Spanish language pack for offline use. Helps with road signs, restaurant menus, and simple conversations in remote towns.
    

Flyhack: Use your hotel or coworking Wi-Fi to download all your maps, podcasts, or translation tools the night before a trip. Set your phone to airplane mode with GPS on, you’ll still be able to track your location via satellite without using data.

Safety Tips for Using Wi-Fi and Mobile Data

Staying connected while traveling is essential, but it’s equally important to protect your data and privacy. In the Dominican Republic, like in many countries, public networks and unfamiliar devices can pose risks if not used carefully. Here are the top precautions to take when using Wi-Fi and mobile services.

Avoiding Scams and Insecure Networks

• Be cautious with public Wi-Fi in airports, cafes, or shopping centers.
  • Many hotspots are open and unencrypted, making it easy for hackers to monitor your traffic.
  • Avoid accessing sensitive information such as bank accounts, passwords, or work email on unsecured networks.

• Verify the correct Wi-Fi name before connecting.
  • Scammers sometimes set up fake hotspots with similar names to trick users.
  • Ask a staff member for the exact network name and password.

• Don’t leave your phone or laptop unattended in public areas.
  • Petty theft can happen, especially in busy cafés or while charging devices.

Tip: If a network doesn’t require a password, treat it as unsafe. Only use it for general browsing or downloads, never for transactions or login activity.

Using VPNs and Encrypted Messaging Apps

• Install a trusted VPN before traveling.
  • A Virtual Private Network encrypts your internet traffic, making it much harder for anyone on the same network to spy on your data.
  • Good VPN options include NordVPN, Surfshark, and ExpressVPN, all of which work well in the Dominican Republic.

• Use encrypted apps like Signal, WhatsApp, or Telegram for communication.
  • WhatsApp is especially popular locally and offers end-to-end encryption by default.
  • Signal provides even higher security and works well on mobile data.

• Secure your email and cloud storage accounts with two-factor authentication.
  • This adds an extra layer of protection if someone tries to access your accounts remotely.

Flyhack: Turn off automatic Wi-Fi connections on your phone. This prevents it from connecting to unsafe networks without your knowledge while walking through public spaces.

SIM Card Theft or Cloning: How to Protect Yourself

• Register your SIM card only at official stores or verified vendors.
  • Don’t share your phone number or ID with unauthorized sellers or individuals offering “activation help.”

• Physically protect your phone.
  • Use biometric locks (fingerprint, facial recognition) and keep it in a secure pocket or anti-theft bag when in crowded areas.

• In case of phone loss or theft:
  • Contact the carrier immediately to suspend the SIM card and prevent unauthorized use.
  • Some carriers, like Clar, allow you to lock your account via customer service or app support.

• SIM cloning is rare but possible.
  • To reduce risk, avoid using your SIM for sensitive two-factor authentication (2FA) unless necessary.
  • Consider using app-based authentication (like Google Authenticator or Authy) instead of SMS-based codes.

Tip: Store your SIM card packaging or registration number in a safe place. It may be required for reactivation or blocking the SIM if lost.

Local Apps That Help You Stay Connected
