4.5 Superb for international calls. Ajayman | 04/01/2010 | See all Ajayman's reviews (9) I have owned a Lebara sim card for at least a year, i put it in a unlocked spare handset i had.I make international calls to Bangladesh,Dubai & USA.When the need arises to make call abroad i simply dial the number & hey presto im chatting away,immediate connection,clear calls. To top up, its dead easy,all leading supermarkets sell top up for Lebara, starting from 5 pounds, you then dial the number & enter the voucher code to activate & top up.Trust me using this is dead easy, for the person who has difficulty in topping up, i suggest you don't have common sense. My 8 year old even knows how to use this. Its a very convenient & handy purchase,Great buy i made.
