Mobile Vikings is a mobile virtual network operator in Belgium that provides mobile phone services without owning its own network infrastructure. It leases capacity from BASE and uses their cell towers. Key benefits include affordable call and data rates, free texts to other Mobile Vikings users, no long-term contracts so customers can easily switch providers, and an online usage overview tool. The company has grown significantly since launching in 2010 by relying on positive word-of-mouth marketing and an incentive program that rewards customers for referring new customers.
