Spain, Movistar. How to register or personal add data?

[base station]

I regularly visit Spain as transit passenger in the Barajas Airport. I have no time to leave the airport. I did not find a Telefonica shop in the airport. My SIM seems to be still active. When I dial a phone number I get redirected to a Telefonica Service number. So I am looking to reactivate it online.

I do not live in Spain, going to shop there is no option. I like to make some phone calls between the flights with a local SIM. Roaming is too expensive, that is why I use Movistar SIM.

Yes, I received a few SMS but I could not react to them because I live abroad.

Now that the date has lapsed, you will need to go to a Telefonica/Movistar shop here in Spain. They might need to issue you a new SIM, although I don't think they will charge you anything.
