trutap

It’s easy to invite friends to trutap. You can invite them via the web site using your online address books e.g. Yahoo, Gmail. Or alternately, on your phone go to your trutap 'Contacts', select 'add contact', then decide whether to import from your phone book or add their details manually. Once you’re done, you’ll be asked if you want to send an invite to your friends. Easy!

"decide whether to import from your phone book"...
I have a motorola w510. I didn't found this option. where exactly is this?

Hi, unfortunately the import phonebook feature is not currently supported on the motorola w510. You can still add contacts though by choosing the manual option, or searching for friends who are already on trutap.
