I have O2 sim card from last 30 months, after extending my previous contract. Now i regret why i did that since the Speed of internet on many places including my office and home is really bad. I moved to Hamburg 9 months ago and every month i need to buy prepaid sim to get internet. I wish, I could get rid of this contract to move to Telekom or Vodaphone, Lebara since their network is better than O2 in Hamburg at least.
