@simaajami,
At this moment, please note that Public Mobile is currently in BETA. They are temporarily accepting new customers only by invitation.
New customers must join the BETA phase at http://publicmobile.ca/en/on/beta
You will be contacted by email within a few weeks. Once you receive your invitation code, you will be able to subscribe on Public Mobile and order a free of charge SIM card.
For now, there is no faster way to subscribe on Public Mobile. They are in BETA to make sure everything works perfectly before the official launch.
