Mobile Broadband 15 GB, cheap, 30 days rolling contract .

Hi, I am an existing customer with 3G mobile broadband. it was a 2 years contract and ended before some days. now it is 30 days rolling contract. At present the same is 16+ per month now (in the market) with 2 years contract. most probably. now i have got unlimited internet and i dont need it anymore. so i will now cancel the contract or i can give it anyone (15 GB at 15 per month, 1 month rolling contract) who needs this. should you have any queries, please ask me. regards murshed khan
