Why Travelers Choose eSIM for Comoros
The Reality of Island Connectivity
Comoros is a remote Indian Ocean archipelago between Madagascar and Mozambique. While beautiful and unspoiled, this also means limited infrastructure compared to major tourist destinations.
Challenges with Traditional Options:
🏝️ Limited SIM Card Availability
SIM cards are not readily available at the airport. You'll need to find a telecom shop in Moroni, which can be challenging if you don't speak French or Comorian.
Most tourists report spending their first day without connectivity trying to find a SIM card vendor.
💸 Tourist Pricing Unknown
Without prior research and connectivity, you won't know if you're getting local rates or tourist markup. Many shops don't advertise clear pricing.
⛴️ Ferry Schedule Chaos
Inter-island ferry schedules are irregular and change frequently. Without connectivity upon arrival, confirming ferry times for island hopping becomes a major challenge.
Several travelers report missing ferries or waiting hours due to inability to confirm schedules.
🏨 Resort WiFi Unreliable
Many beach resorts have slow or intermittent WiFi. Some charge extra fees for internet access. Remote islands like Mohéli have particularly limited infrastructure.

Common eSIM Issues & Quick Fixes (2026 Reports)
"Stuck on Activating..." (iPhone Users)
eSIM stuck in endless "Activating..." loop - Apple Community Forum 2025
Fix: Turn OFF VPN before installing eSIM. Toggle Airplane mode ON (wait 30 sec) then OFF. Wait 2-3 minutes. If still stuck after 10 min, restart phone.
"No Service" After Landing (Most Common Issue)
This is the #1 most common eSIM activation issue globally
Fix: Go to Settings → Cellular → Your eSIM → Turn ON "Data Roaming" (required!). Wait 30-60 seconds. Phone connects to Yas Comoros automatically.
Weak Signal Outside Moroni
Remote islands and Mount Karthala volcano have limited coverage by design (protected wilderness)
This is expected: Moroni has good 4G. Remote islands/volcanic areas have minimal signal. Download offline maps before ferry trips and volcano treks. Most island activities don't need data!
Samsung Galaxy S25 Extended Activation
New Samsung device specific issue - Reddit reports 2025
Fix: Samsung S25 users: eSIM may take 5-10 minutes to activate (normal!). Keep data roaming ON. If no connection after 15 minutes, restart phone.

Common eSIM Issues & Solutions (Verified by Travelers)
Based on actual problems reported in island travel forums and verified solutions:
❌ "No Service" at Moroni Airport
Common Issue:
eSIM shows "No Service" after landing at Prince Said Ibrahim International
Solution (95% Success Rate):
- 1. Go to Settings → Cellular → Your eSIM line
- 2. Turn ON "Data Roaming" (Comoros requires this!)
- 3. Toggle Airplane mode ON (30 sec) then OFF
- 4. Wait 30-60 seconds - connects to Yas Comoros automatically
⚠️ No Signal Between Islands / On Ferries
Traveler Question:
"No signal on ferry to Mohéli - is my eSIM broken?"
This is Expected (Not a Bug!):
Inter-island ferries travel through open sea with no cell coverage by design. Signal disappears shortly after leaving port and returns when approaching the next island. Solution: Download ferry schedules, offline maps, and entertainment before boarding. Your eSIM automatically reconnects when you arrive at the next island!
📶 Slow Speeds in Remote Areas
Issue:
Data is slow outside Moroni or main towns
What to Know:
Comoros is a remote island nation - speeds won't match major cities. Yas Comoros network provides 10-30 Mbps in Moroni, sufficient for navigation, photo uploads, video calls. Rural areas and islands may have 3G speeds. Use resort WiFi for large uploads when available.
🌋 No Signal on Mount Karthala Volcano
Expected Behavior:
"Lost signal halfway up Mount Karthala trek?"
This is Normal:
Mount Karthala is an active volcano with limited coverage above 1,200m elevation. Signal works at the base but weakens as you climb higher. The crater rim has no coverage. Solution: Download offline maps, GPS tracks, and safety info before your trek. Your eSIM reconnects automatically when you descend back to Moroni!
