Nokia Suite isn't compatible with the 301 but if you have your contacts stored there (and have lost your old phone like me!) and export them to another folder on the PC or Dropbox you can transfer them by usb cable.
Once exported drag and drop the .vcf contacts files to the Graphics folder on your phone (they should be viewable with Winows Contacts or Outlook). Then from phone find your contacts in Graphics folder under apps - files. Click mark all under files -options choose share marked - message. Send to yourself - open text - options - show contents. You'll have to click on each one then save (so not a perfect solution if you have 1000s) and the file will then be viewable under your contacts.
