Several businesses say that they can not send me security codes. They say it is because my Republic phone service is VoIP and not mobile or a land line. What can I do?
They are correct that Republic uses VoIP technology. They are incorrect the can’t send you security codes. They may have decided not to send you security codes, but that’s a policy decision on their part, and nothing more.
Most providers offer an alternative like an authenticator app, call or something else.
