How does an eSIM work?
An eSIM (embedded SIM) is a small chip built into your phone. Instead of inserting a physical SIM card, you download a digital profile directly onto the chip. The result is the same - mobile network access - but without any hardware to handle.
How installation works
When you purchase a MondoMate eSIM, we generate a digital profile linked to partner networks at your destination. You install it onto your device via a link, QR code, or by entering the details manually.
- 1You choose a destination and data plan on MondoMate
- 2We issue a digital eSIM profile linked to supported mobile networks at your destination
- 3You install the profile onto your device (via automatic link, QR code, or manual entry)
- 4The eSIM profile is stored on your device's eSIM chip
- 5When you arrive at your destination, your phone connects to the local network automatically
- 6Enable mobile data for the MondoMate eSIM in your settings - you're online
How the connection works
Your eSIM connects to partner mobile networks through roaming agreements. The local network recognises your eSIM profile as a valid subscriber and provides data access according to your plan. This happens automatically.
Multiple eSIM profiles
Most modern phones can store multiple eSIM profiles but only activate one at a time. You can switch between them in your phone's SIM settings at any time.
MondoMate is backed by ONLINECITY.IO and NexCon.io - a team with 25+ years of international telecom experience and access to 525+ networks worldwide.
eSIM works exactly like a physical SIM in terms of network quality and speed. The only difference is that the profile is digital, not plastic.
