How do you transfer contacts on a nokia lumia 625 to a sim card?

To transfer contacts from a Nokia Lumia 625 to a SIM card, you’ll need to use a third-party app, as Windows Phone does not support direct SIM card transfers for contacts. First, back up your contacts to your Microsoft account by syncing them. Then, you can access a compatible app that allows exporting contacts to a file format that can be saved to your SIM card. Alternatively, you can manually copy contacts to the SIM card using another phone that supports this feature.
