Don't waste your money on Lebera. I chose a "pay as you go" service and it burned me 70 pounds in a month for just having 10-20 calls (no more than 20 mins each time) and using some 3G data. The data plan they provide is the most expensive one I have ever seen - 7 pounds for just 1GB.... What's more, they do not allow me to switch to monthly plan with fixed price, so as to take more money from me. After I decided to use Virgin, they refused to provide me the PAC code for transferring my number... It was not until I called them for the third time that they allowed me to have that PAC code... So terrible!
