Is There an Option to Send Photos to Eyefi Cloud Free for Seven Days?

No.

At this time, your Eyefi Mobi card must store all of your photos and videos using an Eyefi app before it can upload them to Eyefi Cloud.

Once your photos are on one of those supported devices, the Eyefi Mobi app or Eyefi Mobi Desktop can sync them to Eyefi Cloud. You can also sync photos from a mobile device to Eyefi Cloud and then have Eyefi Mobi Desktop automatically download them to your computer.

Please see the Where Do You Want to Send Your Photos section for details about the Eyefi apps you'll need to set up for any combination of supported device destinations.
