TracFone. Now owned by Verizon. Fifteen bucks a month minimum. 500 texts, 500 minutes a month 0.5 gigs of data...rolls over every month so it builds up. Or try the free “obama” phones. Or try wifi services( I am not sure you need a number,but you probably can use a free email program and get “text” and other crapola that way). No need for a phone “text” service. Lots of free crap out there.
Tracfone. I second that.
I use so little I had ran out the time limit on my last purchase so I just bought more time for my roll-over everything. A personal observation is that I have a hell ofa lot less painin the ass complaints about my phone service than a lot of everyone else other than premium unlimited hookups. Over the last 5 years I have averaged about $12-13 a month for Tracfone.
