The following are Facebook groups where used carriers can be bought, sold and traded. They are closed groups so you will need to join. Most brands have a chatter group page. If you don’t find it here you can search for it in the FB bar usually by typing brand name and you will see all the groups with that brand in it’s name. Happy B/S/Ting!
