I’ve had some complain that my VOIP phone doesn’t accept text messages. I’ve told them that they aren’t getting my cell number and to deal with not being able to text me. None have walked away from my business.
So far, that hasn’t been an issue with us - everyone has offered the option of an email or voice call for two-step verification (again, so far.)
our business lines from ooma office allow us to accept TXT messages. We do in house financing and when people are late it is easier to get them to reply to a txt than a phone call.
We also use txt at the salvage yard to send photos of parts so they know the exact condition.
Could we live without it? sure, but its nice to have and keeps my personal cell personal :)
