One of the key differences between giffgaff and domestic carriers is that giffgaff places the SIM activation process in the user's hands. While traditional carriers assign numbers through offline stores or apps, giffgaff's streamlined operational model assigns a random number only when you recharge and activate the SIM, delivering the data via OTA technology.
