How do I activate my SIM?

You do not have to do anything besides putting your yallo SIM into your phone once you receive it via mail.

SIM activation date for a new number
Your plan will be active once you receive the SIM. You can start surfing and making calls immediately.

SIM activation date for an existing number
Once your number porting is confirmed, you will receive an activation date. We will activate your plan at yallo on that date. We will send you several reminders by SMS so that you will be ready to insert your yallo SIM in your phone on the activation date.

You can also check the activation date here in my yallo at any time.
