o2: Activate Multicard - how it works
Before you can use your second SIM with o2, you have to activate the multicard. The exact procedure depends on whether you receive your Multicard in the o2 shop on site or ordered it online.
Activate multicard at o2
If you bought your Multicard in an o2 shop, the employee has usually already activated the SIM card. So you can insert the SIM directly into your device and start surfing. However, if you have applied for the Multicard online, you must first activate the SIM.
- To do this, open this o2 website in your browser and log in to your o2 account.
- Change to the tab "Activate replacement SIM and multicard".
- Then enter the 19-digit SIM card number of your Multicard in the corresponding field. You will find the number in the letter that came with your SIM card.
- Then click on "Activate now" to activate the multicard. As soon as the process is complete, you will receive a confirmation via SMS. The process itself usually only takes a few minutes.
