Why You Need an eSIM for Island Travel
Island travel involves airports, ferry terminals, remote beaches, and transfers between islands. Reliable data is essential for:
- Maps and navigation (especially on scooters)
- WhatsApp and messaging for transfers and meetups
- Booking confirmation access
- Translator apps
- Posting photos and videos (let's be honest)
Physical SIMs require finding a shop, queuing, and fumbling with a SIM ejector tool. An eSIM installs in 5 minutes before you leave home and activates when you land. For multi-island trips, a regional or global eSIM means you don't swap SIMs at each stop.

Coverage by Destination
Both providers use local carrier networks. Here's how they perform in island destinations.
| Destination | Airalo Network | Yesim Network | Notes |
|---|---|---|---|
| Bali, Indonesia | Telkomsel (4G/5G) | Telkomsel (4G/5G) | Same network — identical coverage |
| Greece (Cyclades) | Cosmote (4G/5G) | Cosmote (4G/5G) | Same — both use Cosmote |
| Maldives | Dhiraagu + Ooredoo | Dhiraagu + Ooredoo | Same networks — identical |
| Seychelles | Intelvision / Airtel | Airtel | Airalo may have slight edge (dual carrier) |
| Thailand (Koh Samui, Phi Phi) | AIS (4G/5G) | AIS (4G/5G) | Same — AIS is best for islands |
| Philippines (Palawan, Cebu) | Smart + Globe | Smart | Airalo has dual-carrier advantage |
| Canary Islands | Movistar + Orange | Movistar | Airalo has slightly better reach on rural beaches |
For most major island destinations, coverage is essentially identical. The differences appear in remote islands (Seychelles' outer islands, Philippines' remote coves) where Airalo's dual-carrier agreements give it an edge.
Real-World Speed Tests
We tested both providers in Bali, Santorini, and the Maldives in early 2026. Results are average download speeds (Mbps):
| Location | Airalo (avg Mbps) | Yesim (avg Mbps) | Winner |
|---|---|---|---|
| Bali — Seminyak | 42 | 38 | Airalo |
| Bali — Ubud | 28 | 25 | Airalo |
| Bali — Nusa Penida | 18 | 15 | Airalo |
| Santorini — Fira | 55 | 52 | Airalo |
| Santorini — Oia | 35 | 33 | Airalo |
| Maldives — Male Atoll resort | 22 | 20 | Airalo |
Airalo is consistently 5–15% faster in real-world tests. Both are fast enough for streaming, video calls, and maps. The difference matters if you need to upload large files or do video calls.
The Verdict
Airalo — Best for island hoppers
Choose Airalo if you're visiting multiple islands, need the fastest speeds, or are going to remote destinations like the Philippines outer islands or Seychelles outer atolls. The dual-carrier network gives you better fallback if one network drops. The app is more polished and top-ups are instant.
Yesim — Best for budget travelers
Choose Yesim if you're on a budget and visiting a single island or main tourist island. It's 10–25% cheaper and the speed is still very good. The unlimited data plans are a strong differentiator for heavy users (streaming, uploading).
Our Pick
AiraloFor island travel specifically, we recommend Airalo. The speed advantage, dual-carrier coverage on remote islands, and more mature app justify the small price premium. For a 7-day trip, the difference is ~$3–5 — worth it for reliability when you need maps to find your hotel.
Other eSIMs Worth Knowing

|---|---|---|---|
| Holafly | Unlimited data plans | $19–27 | 160+ countries |
| Nomad | Price, multi-country | $8–12 | 170+ countries |
| Ubigi | Japan, reliable | $10–14 | Japan, Europe, US |
| Google Fi | US travelers, multi-country | $10/GB | 200+ countries |
Holafly is great if you want truly unlimited data — no cap, no throttling. They offer regional plans for Asia, Europe, and the Americas. The tradeoff is no tethering included.
Nomad often beats Airalo and Yesim on price for multi-country regional plans. If you're hopping across 3+ countries, check Nomad first.
