Can I activate my card?
Activate SIM card: This is how it works at Telekom, Vodafone, O2 and Co.
At Telekom, Vodafone, O2 and all other network operators there are many different ways to activate the new SIM card. We'll show you what to do with the most popular providers.
Since your new SIM card will be sent to you in the mail, it usually has to be activated before you can use the cellular tariff you have ordered. This is a bit annoying, but an important safety measure. Because if the SIM card falls into the hands of a stranger, it is useless for him this way. But don't worry, activating a SIM card is not difficult. A quick call to your provider's customer service department is often enough.
Your SIM card does not fit in your smartphone? Here we tell you everything about the SIM card sizes, adapters and how to cut them to size.
