The best eSIM for Dominican Republic depends on how much data you need, but for a typical trip eSIM Ahora offers plans from $4.50, activated by QR code in about 30 seconds with no roaming from your home carrier. A 3 GB, 30-day plan costs $9.03. You connect, with top-ups available and nationwide coverage. Compatible with iPhone XS or newer, Samsung Galaxy S21+ and Google Pixel 3+.
Full-speed data every day; after the daily cap the speed is reduced.
Full speed up to 500 MB/day, then 512 Kbps.
Every eSIM can be installed within 180 days of purchase. Plan validity starts when you first connect.
Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Dominican Republic eSIM runs on one network: Altice. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick Altice by hand.
Dominican Republic has three main carriers: Claro Dominicana (largest nationwide coverage with 5G in Santo Domingo and Santiago), Altice Dominicana (5G in Punta Cana and tourist zones), and Viva (Trilogy subsidiary, best value). Plugs are Type A and B (American format, same as the US), 110V — no adapter needed if you're coming from the US. 4G coverage reaches Punta Cana, Bávaro, Santo Domingo, Samaná, Puerto Plata, and main highways.
Punta Cana (PUJ), Las Américas (SDQ), and Puerto Plata (POP) airports offer limited free WiFi. The currency is the Dominican peso (DOP, ~60 DOP/USD); USD is accepted in tourist zones but the rate is unfavorable. Use Banco Popular Dominicano, BHD León, or Scotiabank ATMs — no commission on Visa/Mastercard up to 10,000 DOP. Tips are 10% (sometimes included as "propina legal" on the bill). Watch out at all-inclusive resorts in Bávaro: coverage is good in the hotel zone but may drop crossing to Macao Beach.
