I've just browsed Virgin Mobile website and found they are offering 1000 free text with many PAYG phones. As I am not interested in the free text, I rang the CS and asked if they have any free air time offer. I was then told I can buy 20 pounds air time and get a free brand new Samsung E250 or Nokia 2600.
Also, the air time is on a voucher, I can use it on any Virgin number at any time.
So I bought one at 20 pounds plus 4.88 pounds delivery and the phone & air time voucher will be with me tomorrow.
I think this is a good offer and would like to share it with you.
