Hello,

Much to my surprise after reading that O2 only offer 4G roaming in Germany (which I have experienced, patchy at best especially in crowded areas) I visited Prague and found I had perfect 4G signal everywhere I went at faster speeds than I get at home (Exeter). This was through O2-CZ and I feel this is something for O2 to shout about, as the Czech Republic is a popular destination for UK visitors!

Off to Greece in a week and have very little hope of seeing a 4G signal there...
