Vems Nummer is a free Android app developed by Robert Jonsson. It belongs to the Utilities & Tools category and is specifically designed to help users identify unknown Swedish phone numbers. With this app, users can easily find out to whom a particular phone number belongs.

To use the app, simply click on a phone number in your call history and select the "Edit number before call" option from the menu. Then, complete the action using Vems Nummer. Please note that this description applies to the Samsung Galaxy Nexus with Android versionOther phones and versions of Android may have different ways of accessing the "Edit number before call" option.

If your search results in more than one hit, you can swipe left or right with your finger to browse to the next hit. If you want to save the phone number as a contact, simply click on the image to the left and the phone number, name, and address will be automatically filled in the correct fields.

It is important to note that the app only searches a few common directories, so if the number you are looking for is not in any of these directories, the app will not be able to find it.
