Mrs ERJ and I drove the half hour into Lansing to sort out the phone numbers.
My phone is now a paperweight. According to the button-pusher, Verizon no longer supports Samsung Galaxy 5 phones. The only way to reconnect Kubota's number to his phone involved inactivating the Samsung and now Verizon will not reactivate to the now-obsolete SIM.
This may be a blessing in disguise. I now intend to drop my number on the Verizon plan and switch to a simple, rugged flip-phone Trac-phone. Trac-phone is a pay-as-you-go carrier. I expect to save $70 a month.
One complication is that my number is the "plan holder" so I think I need to make ANOTHER trip to Lansing to sort it out.
