I’m making this as a mental note other than sharing it to the readers. If you are a Smart Communication user and at the same time, an Android or Nokia user these plans are really advisable.
The idea here is that you just use enough rather than paying for too much that you don’t really need. In summary, browsing twitter and facebook (9gag and FML as well) probably doesn’t even take megabytes. Downloading does though. Even usage of messengers are very light on the bytes.
