o2 Genie sim cards are a VERY good buy.
Don`t worry if the first time you top up it tells you that you`ve got 50 free mins when you wanted 300 free text!
You can change what you get free by changing your free Bolt on,just dial 4444 and follow the instructions.
It really is as simple as that.
The O2 Genie card has saved me and my wife alot of money,the only down side is that when its time to "top up" again to get your free text You`ll find that you`ll still have credit left so you dont really want to top up!!!
But make sure you do or you`ll lose out.
You can get these cards FREE from the o2 website!!!!!!
Thanks for reading my guide,I hope it has helped.
