R.I.P English

There are many repeated numbers in the cipher text, maybe this is MONOALPHABETIC.

Maybe each words in the sentences only contain 1 character. Then I realize that this cipher must be an old phone keypad to alphabetic character. For example 444 will be “I” character and so on.

Found.

DI BALIK TIRAI MERAH

Btw, I create a program to decrypt phone keypad to alpha character. Maybe this program will help us if the cipher text is very long. HERE
