Did you try putting a landline phone number in? Many times they'll check their database and see that it is a landline and use an automated call system instead of a text. Just don't be on a VOIP connection because that's what spammers use.
My landline provider is using VoIP and has been for a decade.
The good news is that it protects me from having a yahoo, google, facebook or any other accounts with stupid requirements to feed surveillance capitalism.
