They don't need Internet access to do phone sales. There are plenty of companies that have an agent/consumer friendly e-app process. I don't do business with companies that require email for e-apps. Fortunately the ones I use are also the most competitive in most situations.
In my home state (Florida) there really aren't any options for that-UHC/AARP has no Eapp for Med Supps without a face to face meeting and they are by and large the lowest rates statewide with a few exceptions.
