How to encrypt using Multitap cipher?

Multitap replaces a letter by repeated digits defined by the corresponding key code on a mobile phone keypad (This mode is used when writing SMS/Texto).

The correspondence table is:

A2B22
C222D3
E33F333
G4H44
I444J5
K55L555
M6N66
O666P7
Q77R777
S7777T8
U88V888
W9X99
Y999Z9999
