If you are looking for savings as an option, its better that you DONT EVER use Clay Sim Cards. I used it for UK and regretted it big time. Even after they blocked 10k on my credit card as buffer money, they billed me for 20k for a week!! Imagine with no data activated and calls made not more than a few minutes i got billed for 20K!! While i checked the records, most of the calls were repeated and over charged by 5 times! It has taken me more than 15 days to sort this mess out and finally have the 5k billed cleared! Never recommending this to anyone !
