Microsoft rolls out cellular data app for own SIM card

The company did not disclose in which markets it would sell the SIM card, though it said in information provided with the app that the service would be available in some markets and offers are for domestic plans only, with international roaming offers to be available soon.

Users can purchase a plan through a Windows Store anywhere network coverage is available, the company added. They have to click on the Wi-Fi icon in the app and choose Cellular data from a list of networks.

The publication of the app to the Microsoft store, first noticed by The Verge, follows a deal announced by French company Transatel  that it has been selected by Microsoft to support an upcoming paid cellular data service for Windows 10.

"Laptops and tablets equipped with Windows 10, a cellular broadband modem, and a Microsoft SIM Card utilizing Transatel’s 901 technology, will allow consumers to easily and conveniently purchase pre-paid 3G/4G-LTE data services," Transatel said in a statement on Monday.

Transatel said it would provide the cellular data service, which Windows 10 would make easy and convenient to purchase. The company provides 3G/4G-LTE connectivity in over 38 countries with plans to increase coverage to 50 countries by the end of the first quarter. The company claims that its SIM 901 provides local plug-and-play 3G/LTE connectivity in many countries because of the company's agreements with mobile operators across the world.

Apple also offers a SIM with select models of its iPad tablet, which lets users switch mobile carriers without changing their SIM card when traveling abroad.
