Answers to Questions
What is the configuration of the keys on a phone keypad?
By default, letters are associated to digits according to this arrangement :
| 2 | ABC |
|---|---|
| 3 | DEF |
| 4 | GHI |
| 5 | JKL |
| 6 | MNO |
| 7 | PQRS |
| 8 | TUV |
| 9 | WXYZ |
How to recognize T9 mode?
T9 has short numbers, whose length is equal to the letter number in the word. There is little repetition of the same digit.
Example: MESSAGE=6377243
How to recognize ABC mode?
The ABC multitap has long numbers (much longer than the original word), with many repetitions of consecutive digits (successive presses on the same key).
Example: MESSAGE=633777777772433
