Unlimited Data

The rate at which Lebara charges is so high and should be checked

You mean usage to price? I.e I've used 25g from approx 6 hours of streaming.

Yes, you are right in your usage but one thing I have noticed is that my rates are different. For example I have been doing unlimited date for over 6months now and I spend £25 to subscribe but others do so with £12.5. why is mine different. It is so unfair on me ..hence my conclusion on Lebara
