Question 1

What is a travel eSIM and how does it work?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM chip built into modern smartphones. Instead of inserting a physical plastic card, you scan a QR code to download a data plan profile and instantly connect to local telecom networks when traveling.

Question 2

When should I install my eSIM?

Accepted Answer

You can install your eSIM right before departing or upon arrival at your destination using airport Wi-Fi. Most plans only activate their validity timer when they connect to a supported network in the destination country.

Question 3

Can I keep my WhatsApp number and physical SIM active?

Accepted Answer

Yes! Modern dual-SIM phones allow you to keep your primary physical SIM active for calls and SMS/WhatsApp verification while using the MileSIM eSIM exclusively for high-speed travel mobile data.

Question 4

How do I check if my phone is eSIM compatible?

Accepted Answer

Dial *#06# on your phone keypad. If an EID (Embedded Identity Document) number appears on your screen, your device hardware supports eSIM technology. Carrier-unlocked iPhones (XR and newer), Google Pixel 3+, and Samsung Galaxy S20+ are fully compatible.
