Everything You Need to Know About eSIM
Discover how eSIM technology is revolutionising international mobile connectivity. No physical cards, no waiting, no hassle.
What is an eSIM and how does it work
An eSIM (embedded SIM) is a chip built directly into your mobile phone that performs the same function as a traditional physical SIM card, but without the need to insert or remove any card. Instead of receiving a plastic card that you must manually place in your device's SIM tray, with an eSIM you simply scan a QR code or enter an activation code, and your mobile data profile downloads and installs digitally in a matter of seconds.
eSIM technology was standardised by the GSMA (the global association of mobile operators) and has become the industry standard for modern mobile connectivity. Since 2018, major smartphone manufacturers have integrated eSIM support into their devices, and adoption has grown exponentially. Today, the majority of mid-range and flagship phones support eSIM, allowing users to manage multiple lines and data plans without handling physical cards.
It's that easy
eSIM advantages for travellers
Travelling with an eSIM completely transforms the connectivity experience abroad. Instead of searching for a local carrier shop or paying steep roaming fees, you can have your data plan active before you even board the plane.
Instant connectivity
Activate your data plan before travelling. As soon as you land and turn on your phone, you will have internet access with no waiting or queuing at local carrier shops.
Keep your home number
When using eSIM for data, your main physical SIM stays active with your regular number. You can receive calls and verification SMS on your usual number.
No roaming charges
Most modern smartphones support using a physical SIM and an eSIM simultaneously. Keep your home line for calls and use MiMobile's eSIM for data abroad.
Works worldwide
Some devices allow storing several eSIM profiles (up to 8 or more on recent iPhones). Ideal for frequent travellers visiting multiple countries on a single trip.
Easy setup
There is nothing physical you can misplace, and you do not need special tools to open the SIM tray. Nano-SIM cards are tiny and easy to lose.
Eco-friendly
eSIMs eliminate the plastic of SIM cards and associated packaging, helping reduce electronic waste. No card, no packaging.
