Thanks a lot Petkow for your help.
I now checked, had translated the FAQ (
PROMT - Free Online Translator and dictionary - English, German, French, Spanish, Italian, Portuguese (Brazilian) and Russian languages.) and enjoyed.
The minimum consumption I'll spend for SMS in other EU countries....
I got the SIM in a Media markt in Pamplona for 10€ including 10€ balance
and including a free unlocked mobile ALCATEL OT-103 which properly works with my german VF CallYa SIM.
Do you know if there is a way to recharge with german i.e. E-Plus or BLAU vouchers too?
My swiss sunrise SIM for instance accepts german o2 vouchers.
