The Government has asked operators to decrease their rate and Telkomsel has done it. Check their website for the official announcement. It doesn't change much for me (Simpati users) as i only use short distance call. But for those who often use long distance call (not international call, but calling to an area which is quite far from the place you are calling), it may get the benefit from this new rate. Most of the long distance rate are now flat, meaning there are no difference for zone 1, 2, or 3.
I wonder why Simpati who has the most customers are still much more expensive than the other products.
