I read the reviews here and thought they were too good, but I have to say that Lebara is the BEST mobile provider out there. They use the Vodafone network, so signal is good, and inclusive of roaming and international calling. Customer service is superb (shout out to Madhuri Wanjari) and second to none. The call centre is responsive and knowledgeable. I came from Voxi. Don't get me started on Voxi, take a look at their reviews on Trustpilot...!!
