Yesterday, I finally ended my account with Optus. I was with Optus for around 10 years. Why did I do such action? I am still very happy with Optus service. That is only because I found a provider is more suit for my needs. They are Amaysim. They are no minimum spending and I need to pay what I spend every month. That is what I want! I don't need a free mobile phone and extra bonus amount on my plan. I got my Galaxy S and connect with my friends via skype and msn, which can be done in mobile internet. I don't need to use voice calls that much. Moreover, they only charges 15 cents per minutes. My previous plan is $19= 127 minutes in Amaysim. I don't need to use that much. Thus, I think I can lower my mobile phone bills!
