Your complete guide to using eSIMs abroad — simple, fast, and perfect for travelers & seafarers.
If you’re planning to travel abroad, one of the biggest headaches is staying connected. Buying a local SIM at every airport is expensive, time-consuming, and sometimes confusing — especially when you’re hopping between multiple countries.
That’s why eSIMs have become the most popular travel essential today.
They’re fast.
They’re cheap.
They’re convenient.
And they work in over 190+ countries.
Whether you’re a tourist, OFW, seafarer, backpacker, or business traveler, here’s a complete, easy guide on how to use an eSIM for international travel — even if it’s your first time.
What Is an eSIM?
An eSIM (embedded SIM) is a digital SIM already built into your phone.
You don’t need to insert anything — no physical card, no swapping SIM trays.
You simply scan a QR code → your travel plan activates → you get data abroad instantly.
What you can do with an eSIM:
- Switch between networks with one tap
- Use mobile data abroad
- Stay online for maps, calls (via apps), hotel bookings
- Avoid expensive roaming fees
- Buy multiple eSIM plans for multiple countries

- iPhone (XS and newer): supports eSIM.

- Google Pixel: Pixel 3 and newer support eSIM.
How to check:

Tips for Using eSIM Abroad (Things Travelers Usually Forget)
1. Keep your PH SIM for OTPs
Don’t delete your main SIM — you can keep it active while using the eSIM for data.
2. Turn OFF data roaming on your PH SIM To avoid unwanted charges.
3. Track your data usage. Unlimited plans often have fair-use policies (FUP).
4. Download the eSIM QR code before your flight. Some airports have weak WiFi.
5. Use WhatsApp, Messenger, Viber for calls
eSIMs mostly offer data-only plans, so app calls are your best friend.
