I have VOIP and I think I have run into that problem a couple of times in the past, so I put in my old landline number that I haven't used since 2010.
It was accepted so I operate on the old saw, don't call me I'll call you.
I don't give out my phone number to many folk anyway beyond family, friends, bank and doctors.
I bought something at Harbor Freight last summer and the clerk asked me for my phone number and I said you don't need my phone number, and he said I guess your right.
Yup, I’ve run into,it numerous times- and usually they need to text a verification code or whatever, and I then can get what it is I’m after. I had voip for free with “text now” app, and bought a humber for a few dollars for the year, only now it doesn’t work(the text now app) and I have lost the number as a result. Looking for another free voip app now.
Yeah I don’t give out my number to store clerks either- and quite a number of places now want the phone number- maybe they get a % when spam companies buy the lists of phone numbers or some thi .
