Q: can i export my contacts to my sim card?

This is not supported, you can only import from your SIM card. After that you'll have to export your contacts from your contact app on your computer, or send the info one by one from your contact app on the phone.

No but here is a work around I used. Search the app store for "export contacts." There's a bunch of apps capable of doing it. Filter through the paid apps and you'll eventually find a free one that can export to different file formats. I then was able to add them to the SIM card at my cellular provider's store.

My wife's phone syncs to my comptuer but she does not sync her contacts. I have lost so much data the last few years syncing things so I wanted to make sure I had a csv file of her contacts when moving them to a different kind of phone.
