If you're on the 55+ plan, texting between phones in Simple Choice countries is free. You should enter all phone number in the "+" format (e.g. +1.234.567.8901). You may also be able to use VoIP calling apps, like Viber, Skype or Hangouts for free.
I was told we should dial #766# to enable texting overseas. Then what? hit send? reboot the phone? and can Iwe use our contact list?
