In a move that is sure to give executives and customer service reps from other carriers a major headache, Vodafone UK has announced that it will be doing away with all roaming charges. The change applies to both Pay As You Go and Pay Monthly customers from June 1st until the end of August, and applies to over 35 European countries. The only catch is that customers must sign up for Vodafone Passport in order to enjoy calling, texting and picture messaging at the same rates as at home. As for which countries are included in the Summer promotion, it seems that every major European destination is covered: Albania, Andorra, Austria, Belgium, Bosnia, Bulgaria, Canary Islands, Channel Islands, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Faroes, Finland, France, Germany, Gibraltar, Greece, Hungary, Iceland, Isle of Man, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Monaco, Norway, Poland, Portugal, Republic of Ireland, Romania, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, The Netherlands, Vatican City, New Zealand, and Australia. To opt into the promotion, text “Passport” to 97888 if you are a Pay Monthly customer or 2345 if you are on Pay as you Go.
