Celcom, Maxis sucks. The real fact is you don't know how to get the best internet! I can give you simple tips for all internet users in Malaysia.
1. Choose your internet plan wisely. This is the common tip to know how much quota will be used depends on type of your internet usage.
2. Let's try figure out which network telecommunication has the best service in the specific area. If it has excellent line and coverage, it also means the internet coverage and speed also good.
3. Don't ever play online game like Dota 2 by using broadband because it will use much quota and suddenly your speed of internet will be throttled.
4. Mobile internet is easy to use compared by using device. It surprisingly cheaper because you don't need to pay a fee of internet device such as modem.
5. Streaming video online uses your quota so much.
6. If you using broadband in your house and sometimes can't find the connection, you can try moving your laptop or desktop near the window.
7. If you play online games, make sure you choose the suitable server depends on the country. If Malaysia, choose SEA server if available. The benefit by doing this is you will have stable and smooth connection during playing games.
8. Use VPN software to bypass some websites that blocked by our country such as Netflix. My favourite one is MyTunnel VPN Software.
9. You need to know this, especially when you want to buy new internet. As example, the speed of internet as shown on the advertisements is 1Mbps. It means you need to divide the 1000 bytes by 8 to get actual speed of your internet.
