WiFi speed, SIM cards, and data plans in Puerto Viejo Costa Rica are the infrastructure questions that every digital nomad asks before committing to a stay on the Caribbean coast. The honest answer is better than the reputation suggests — fibre internet is genuinely available in the main areas, mobile data coverage is solid, and the combination of home fibre plus mobile backup is a setup that most remote workers find entirely functional. This guide covers the real numbers, the real providers, and the backup strategy that keeps you working through Caribbean coast variability. 📡
Real WiFi Speeds — What to Actually Expect
The range in Puerto Viejo is wide: a well-maintained long-term rental in Playa Cocles on a fibre connection will test at 40–100 Mbps consistently. An older property in a less-served area on a cable or ADSL connection will test at 5–15 Mbps with more variability. The difference between these two categories of connection is significant for video call quality and large file transfers. It is not significant for normal browsing, email, or even streaming video. 💻
The critical practice: ask for a real-time speed test at any specific rental before committing to it. Not a claimed speed. Not what the landlord says. A screenshot of Speedtest.net taken while you are connected to the property's network. Any landlord worth renting from will do this without hesitation. One who gets vague or defensive about internet speed testing is telling you something useful.
Fibre vs Cable — Why It Matters
Fibre connections (available through ICE/Kolbi fibre service) provide the most consistent speeds with the lowest latency — typically 30–100 Mbps symmetrical (same upload and download speed). This symmetrical speed matters specifically for video calls, where upload speed is as important as download. A 100 Mbps download / 5 Mbps upload connection will struggle with multi-participant video calls despite its impressive headline number. Fibre gives you both. 🔧
Cable and ADSL connections — older infrastructure still present in some properties — tend to be asymmetrical (faster download than upload) and more variable in speed. For nomads who need consistent video call quality, fibre-connected properties are significantly better. Ask specifically about connection type, not just speed.
Best SIM Cards in Puerto Viejo
Kolbi (ICE) — Costa Rica's national telecommunications provider has the most comprehensive 4G/LTE coverage throughout the Puerto Viejo corridor, including the southern beaches toward Manzanillo. Coverage in Punta Uva is more consistent with Kolbi than with other providers. Buy at any ICE office, major supermarket, or pharmacy. Affordable prepaid SIMs available without ID requirements for tourists. 📱
Movistar — Strong 4G/LTE in the town center and Cocles. Competitive data plan pricing, particularly for higher-volume packages. Slightly less consistent coverage than Kolbi in the more remote southern areas. Good second choice or alternative if Kolbi signal is weak at your specific location.
Claro — Less consistent coverage in the Caribbean corridor. Generally not the first choice for Puerto Viejo specifically, though it works adequately in the town center. Worth having as a third option if you are doing extended stays in areas where Kolbi and Movistar both have weak signal.
Data Plans — What They Cost in 2026
Prepaid data packages from Kolbi and Movistar run approximately $8–20 for 10–30GB depending on validity period and package structure. Both providers offer weekly and monthly packages. Top-up credit is available at any supermarket (AMPM, Palí, BM), pharmacy, or convenience store — you will see the yellow ICE/Kolbi signage or Movistar red throughout town. The process is simple: buy the SIM (inexpensive), register it (requires a photo of your passport at purchase in most cases), and top up the credit you need.
For nomads doing an extended stay, a monthly data package of 20–30GB is the right amount for backup use — covering the outage days and any sessions in areas where your home WiFi is not accessible. It is not intended to replace your home fibre for primary work use, but as a backup it is more than sufficient.
The Backup Strategy — How It Works in Practice
The setup that experienced nomads in Puerto Viejo use: primary fibre connection at home for normal work. Kolbi SIM with a monthly data package in a dedicated mobile router or phone hotspot for outage coverage and café sessions. Some also use a second SIM from a different provider for maximum redundancy. The cost of this dual-SIM backup approach is approximately $15–20/month — a negligible line item against a comfortable remote work budget. 🛜
The psychological benefit of this setup is as important as the practical one: outages stop being work-stopping events and become minor inconveniences that you handle automatically. The Caribbean coast variability stops feeling like infrastructure failure and starts feeling like a normal Tuesday.
