Dont go for Telkom Mobile data if you are a SW developer

You are probably better off setting cloudflare 1.1.1.1 as primary and 8.8.8.8 as secondary. They work the best. Fast website loading times. Telkom DNS has been unreliable and you will end off thinking the internet is down when it's just bad DNS.

Also @OP CGN is carrier grade nat which gets implemented when you use the internet apn so best to use unrestricted if you basically do anything other than facebook or youtube because even gaming can be problematic when using party chat on xbox or ps4 for example even p2p the unrestricted apn is best.

Using an alternate DNS helps a lot. I found this guide helpful for setting an alternate DNS (1.1.1.1 and secondly 8.8.8.8) https://developers.google.com/speed/public-dns/docs/using
