Activate Nano SIM - how it works

At Telekom, Vodafone and O2 there are different ways in which you can activate your nano SIM card for the iPhone 5 or iPad Mini. We'll show you how it works with the three major mobile operators.

Unlock the Telekom nano SIM card

If you have exchanged your normal SIM card at T-Mobile for a nano-SIM, simply go to the website of the mobile phone provider set up specifically for activation. There you enter your mobile phone number, the number of the old and the new SIM as well as your customer account number. That was it.

Regardless of whether you are an existing or a new customer, you must activate your nano-SIM with O2 in any case. To do this, go to the activation page of the provider and choose whether it is a new or existing contract. Depending on the situation, enter the card number in the window that then opens or log in with your access.

Nano SIM activation at Vodafone

Vodafone does not provide a homepage for activation. As a new customer, all you have to do is insert the nano-SIM into your iPhone 5 or iPad Mini and you're ready to go. Existing customers receive detailed instructions and a hotline number when the card is exchanged. Call them, enter the card number and have the SIM activated.
