eSIM INSTALLATION & ACTIVATION
What is an eSIM?
eSIM is a physical yet digital SIM. It is embedded into certain mobile phones, tablets and smart watches as a small electronic chip. A QR provided by us enables you to activate the eSIM in a few easy steps, before connecting to 1O1O’s network.
You can swap the SIM card via settings, instead of inserting a new physical SIM card after removing the old one.
Existing customers using a physical SIM can change to an eSIM at one of our outlets.
Why an eSIM?
You can manage multiple eSIMs easily via “Settings”, which means you can separate SIM card usage – eg private or business.
You can keep a roaming SIM standing by, thereby removing the need to purchase a new one each time.
Unlike with regular SIM cards, no specific slot is required and there’s no way you can lose a card.
How do I activate?
Visit any 1O1O center to subscribe to a new number, port-in or replace an existing postpaid number on an eSIM. Scan the QR code following the device activation process. You can start enjoying service after the eSIM is activated.

If I have two mobile phones, can I use them with the same eSIM?
No. eSIM for Android smart devices will only work with one smartphone.

Can I reuse the eSIM QR code on the same or other devices?
No. Once an eSIM voucher’s QR code is downloaded and installed, it will be invalidated immediately, regardless of device concerned.
