To import the contacts, you will have to make sure that the contacts are in a Vcard format. Also, a Bluetooth is required to send the file. If you don't have PC with Bluetooth enabled, use another phone and copy the Vcard to that phone. Initiate a file-transfer and select the Vcard. The Modu T will automatically detect the file's contents and it will add the corresponding contacts.
Or to make it easier, sync those contacts to an empty SIM on another phone, then replace the SIM in Modu T and copy the contacts.
