I bought a o2 pay & go sim card from the o2 shop for a spare phone I have aquired. When I got the sim the woman mentioned something about 'gene' free text messages. I topped up the sim card with £10. That was 4 months ago and the sim keeps topping up with 300 texts every month even though I haven't added any more money to the sim. Is this the case that you get 300 free texts per month even though you haven't topped up?


- they always said o2 was the best network in terms of value
