I am not a native speaker and cannot figure out the solution. I tried to replaced the numbers, by keeping the given order. 3 must be a „D“, „E“ or „F“, 2 ABC and 1 is nothing I guess, so I do not have to take into account. The remaining numbers were translated in the same way. Please, could I have another clue.

Even if I rearrange the letters, I do not get a meaningful solution. I desperately need another hint.

Now select them in the order of the phone number. [/spoiler]
