Review of Telkomsel

I have recommend simpati telkomsel as provider for all my friend. I because I have experienced the wide range of good connection that I can get even when I am at small village.. But unfortunately, they fail to keep their strength. The connection both for call and Internet is very very unreliable. Very annoying when I called somebody there was very spooky and strange noise distruct during the conversation and it happened many many times..and more over they increase the price. I agree with that only if they could maintain their quality.
