Running out of data at Angkor Wat when you need your map to find the exit is not a great experience. I’ve been there. Here’s exactly how to stay on top of your Airalo eSIM data usage so you never hit zero at the wrong moment.
Method 1: Check via Airalo App
The simplest method:
- Open the Airalo app
- Tap My eSIMs
- Select your active plan
- View the data usage display (remaining GB and expiry date visible)
Airalo updates this in near-real-time. It’s the most reliable source because it reads directly from the network.
Important: The Airalo app requires an internet connection to update. Check it while connected to WiFi, or use a small amount of your eSIM data to refresh it.
Method 2: iPhone Settings
Checking data on iPhone:
- Go to Settings > Cellular (or Mobile Data)
- Scroll down to find your eSIM line (it’ll have the name you gave it, or your operator name)
- Tap it — you’ll see current period usage
Important caveat: iPhone tracks usage since your last reset, not since your plan started. This is useful for monitoring daily usage but doesn’t tell you your remaining plan balance. Always cross-reference with the Airalo app for the authoritative remaining balance.
Reset your counter at the start of each trip: Settings > Cellular > scroll to bottom > Reset Statistics.

Method 3: Android Data Monitor
Samsung / Android:
- Go to Settings > Connections > Data Usage
- Select your eSIM line
- Set the billing cycle to match your plan start date
- View usage breakdown and set warnings
Android advantage: You can set a data limit that automatically cuts data at a threshold (e.g., warn at 2.5GB remaining out of 5GB). This is excellent for budget-conscious travellers.
Setting Up Usage Alerts
iPhone: Settings > Cellular > Cellular Data Options — you can enable Low Data Mode to reduce background consumption, but iPhone doesn’t have a built-in alert threshold.
Android: Settings > Connections > Data Usage > Billing Cycle > Set Data Limit. Set a warning at 500MB–1GB before your plan runs out.
Airalo app: Push notifications are available when you’re running low. Ensure notifications are enabled in your phone settings for the Airalo app.
Apps That Eat Data Silently
Common background data consumers that drain your eSIM without obvious activity:
- iCloud/Google Photos auto-backup — disable on mobile data
- App Store auto-updates — disable
- Instagram/TikTok auto-play — disable
- Maps downloading tiles — only downloads when actively navigating
- Email with large attachments — consider switching to WiFi-only sync

What To Do When You’re Running Low
- Top up directly through the Airalo app — purchase additional data for your current plan (where available) or buy a new plan
- Switch to Low Data Mode (iPhone) or Data Saver (Android) to reduce consumption
- Identify a WiFi source — most cafés, hotels, and airports have free WiFi for non-critical tasks
- Prioritise: keep maps and messaging active; pause streaming and social until you top up
FAQ
How do I check remaining Airalo data?
Open the Airalo app > My eSIMs > select your plan. Remaining data is displayed in real-time (requires brief internet access to update).
Does iPhone show eSIM data separately?
Yes — Settings > Cellular shows each line separately, including eSIM lines. However, it tracks from the last statistics reset, not from plan start.
Can I set a data usage alert for my Airalo eSIM?
On Android, yes — through Settings > Data Usage > Set Data Limit. On iPhone, Low Data Mode reduces consumption but doesn’t alert at a specific threshold. Airalo app notifications alert when running low.
What happens when my Airalo data runs out?
Data stops automatically. You won’t be charged extra — you simply need to purchase a top-up or new plan through the app.
How accurate is the Airalo app data reading?
Very accurate — it reads directly from network-reported usage. May lag by a few minutes under heavy use.
