Budget MVNO FreedomPop launched a new application in the UK giving customers on any network access to its free voice and text tariff, without having to purchase the company’s SIM card.

The US-based company, which launched services in the European country last year, said UK mobile users on any wireless network, with any device, will be able to get 200 voice minutes and 200 texts for free through the application.

At launch, the company is also offering 300 minutes of free international calling to more than 60 countries for the first month of service.

The move sees the MVNO expand the availability of its “free” offering, with users now not even expected to buy the company’s SIM card. However its free data offering of 200MB will not be accessible via the application.

Users will also have the option to upgrade to an unlimited voice and text plan for £3.99, “making it the lowest cost unlimited plan in the country”, said the company.

FreedomPop’s model is designed to encourage its users to buy add-on services, on top of its free package, and the company’s founder Stephen Stockols told Mobile World Live earlier this year that it was beginning to see a high number of its users adopting paid services.

Jon Simm, FreedomPop’s general manager in the UK, said the launch of the application was further evidence of the company’s commitment to developing over-the-top offerings.

“While many carriers are resisting over-the top-threats, FreedomPop is embracing it,” he said.

The company also announced it has begun to sell low cost pre-owned smartphones from brands like Samsung, HTC and Huawei.

“For those that have been looking to switch to FreedomPop, but couldn’t find an affordable smartphone, we are making quality smartphones available at great value,” added Simm.
