RW sent me a new Sim card to supposedly improve my cell coverage in Colorado.  I installed two days ago and ever since have not been able to make outgoing calls over cellular network.  Incoming works fine (both WiFi and Cell), but outgoing only works on WiFi.  I've tried every help topic posted on this site, in addition to what RW help instructed me to try - still doesn't work.  I even re-installed the Sim card to see if anything different and nada.  Now I'm not even getting any other help/response to my open ticket!  Anyone else have this issue?  P.S.  The automated message I get when trying dial out, over cell, is:  "The number or code you have dialed is incorrect."
