they are faster to type from a feature phone.
verification codes don't have to be long. 4-7 numbers with limited amount of retry is plenty.

My customers are entering the verification phones through a computer keyboard, they are only receiving the SMS verification messages to their mobile phone once so I can verify that they own a phone.
Unless you were assuming that their "browser" they would be entering the verification code into is on their feature phone?
