What to do with expired SIM cards?

You can make a Pen stand if you have too many of them , my friend had one. It looks cool and different. Else you need to littre.

you break it before disposing

break them as they will not be re-usable.

I dont think you can do anything with these sim cards..better throw them offf without burning!!

throw in trash

best to keep it wd u, as the mobile companies use to reactivate expired SIM cards in special schemes.

well you can still use it as back-up of your telephone directory of your contacts in case your working sims become damages in certain ways or lost with your phone. you may go to your service provider for re-activation but it cost as brand new sims but you will still retain your old number, ther are lots of way to do on your sim's you can make it as "pick" on guitar if you where a musician or use it as spacer if your table is not level or moving. before you throw something, think of usefull way that you will never to buy for something else

Mobiles usually can be operated only when SIM is inserted(There are exceptions). A couple of times I bought a new mobile & I didnt have a SIM to test the mobile. Its good to have them as a spare to use as contact store.

If they are expired then they cant be used to make or receive calls though the data on the sim cards like phone numbers and messages can be misused so its better to remove the data and break them n then dispose,you can keep one as a spair though cos if you have an extra phone which requires a sim card to be put in to start,you can use one of the old ones :)
