That only works if you have this kind of keyboard showing:
This kind of keyboard knows nothing about the numbers that go with the letters on a phone keyboard:
The first keypad that I have posted the screenshot for is a combined keyboard that has certain letters assigned to certain numbers. The second keyboard knows nothing about that configuration. It's just a keyboard. Alpha characters are alpha characters, and numeric characters are numeric characters. And never the twain shall meet.
536682267 does not equate to any letter on the second keyboard. And even if you had the 1st keyboard, which of the three possible letters does each number equate to? Is 5 = j, k, or l? Is 3 = d, e, or f? It's not a one for one. So, you can figure out what number the word DEALT would be (33258), but you can't figure out which letter you should type on the alpha-numeric keyboard if you are trying to represent a 5.
