Made online activation easy

In some reviews you can read, that there were problems with the activation of the SIM card. Because waiting after inserting the SIM card in the mobile phone to an automatic activation, the etc never done .. In my opinion, these are reviews completely incomprehensible.
Before activating the card by O2, the card must first be registered by the user. As for the registration and activation verification of customers via identity card number is necessary (so that not everyone come and drive fast and loose with it), it is futile, "automatic activation" to wait for. (To my knowledge, there is this, this approach not only with CO2, but also with all other wireless carriers.)
Again, who can read is a clear advantage. In the case where the card is delivered, is "more information for you: [...]". There you will find among the FAQ item "How do I activate my SIM card?" This can be done by telephone or easily online - directly behind the following link ([...]). They will run with sufficient assistance by registering. Attention: keep identity card or passport ready. The final review of the data takes a while but then the call is no more obstacles.
Now it should fix the last one.
