Not sure, had the old one and gave it to my friend as I have free texts anyway. They blocked her phoen. If you had the old one and was able to use it and still have your sim card you are very lucky. If you get another code just use another sim card. Buy a cheap one for like £3 or something. If you are between 16-24 you can get a Blyk sim card wth 217 free texts and 43 free minutes to any network. The only catch is they send you have to have a picture message phone so they can send you adverts. My little brother has one, he doesn't use it for personal calls just the free texts. The adverts are ok anyway as you can get money off vouchers etc. Not a Blyk rep just think its helpful to inform people of the latest offers etc. Hope this info helps anyway: )
