Simple connection : Telkomsel Balikpapan, S*CK !!!

What you want is just simple connection, connects you to your relative, family, friend.
You can talk, you can chat, send messages, browsing, all just simple stuff you want.
Simpati, mentari, xl, fleksi, etc? Which one to choose?
My experience :
- Fleksi, local cdma, prepaid/postpaid, cheap, networks is limited to cdma 2000x 1x, but it is so stable, 10-15kBps. I use it for my home network, everyone happy at home, Unlimited internet monthly for 50k rupiah
- Mentari, national gsm, prepaid, i have been using this for 6years, great bonuses, network quite fast but a little bit unstable. My best gsm i ever try.
- Simpati, by telkomsel. They said they are the best, they said they are the fastest, the stablest network. But in my experience in this 2 months, they S*CK !!
90% times i try to make a phone call, it always said network busy. 90% times i try to connect to network to reach internet, it wont connect, or at the end connected with lost sync issue, mostly 1kBps when connected. I tried the unlimited data plan, they said max 384kbps, but to reach 5kBps is hard, when it able to connect. Their bonusses scheme works at early morning, am I a bat !!?
The worst thing is i need to use telkomsel as in my work place all use it, what a crap. Telkomsel need to learn from it's cdma brother. Telkomsel is S*CK !!!
