For me, I maintain 2nd tactical phone, pre-paid. Always happy to receive mass sms from my OKTs without worry. Used to have a gadget to put 2 sim cards in 1 phone, but they seem unreliable, so just use 2 phones now. My tactical phone is kept under car mat at driver's side when not in use. (I'm the only driver)

Of course, everyone will have special circumstances, and must find a way that works best. However, to get all OKTs to work out a system seems impractical.

When considering your options, one should ASSUME that the OKTs WILL mass SMS you with incriminating messages. Also one MUST assume that your normal phone WILL be read by someone else. After considering this, only then will you be able to make a relatively secure choice.
