Trying to activate a jamobil card, what I am supposed to put in the vorwahl field? 😭

Man I literally searched for the Spanish vorwahl to put it and it says it doesn’t exist, I tried 34, 0034 and 034 and nothing, like how the hell am I supposed to get a German phone number if you are asking me for another phone number and won’t let me use the one from my home country?!?!
