Re: 2025? That long?
"[...] and claim they'll send SMS messages, but a feature phone would work fine for that.
My BT landline number happily accepts SMS messages. BT transcribe the text into an acceptable voice message. On that basis there is no reason for organisations to refuse to send text messages if you don't have a mobile.
I don't place orders with companies who insist on only a mobile number for any possible last-minute delivery messages. Any such messages are usually voice ones anyway to say they are arriving soon.
