Hi! we will be traveling to Spain in July and would like to have access to 3G service while we are there. Does anyone know where we might be able to buy a prepaid card for use while we are in Spain (preferably in Madrid as that will be our first stop)? We would need a microSIM card that is available without a Spanish bank account or credit card. We will need service for about 10 days, mostly for email and GPS, but don't want to have to rely on finding available Wifi. Info that I have read seems a bit confusing - maybe Orange sells one for 20 euros but it didn't seems clear if that was available to tourists...??? Thanks!!
