QuarkSe is leading the eSIM liberation by launching the world’s first eSIM Global Distribution System (GDS). Our GDS simplifies and improves the user experience when traveling or living internationally by enabling mobile operators (as well as commercial partners such as travel service providers) to offer consumers easy and convenient seamless branded access to a local eSIM at any destination in the world at affordable local prices. Our GDS also enables IoT companies to distribute their equipment globally (such as connected cars, smart watches and wearables) whilst remaining always best connected using a local eSIM. The QuarkSe GDS makes traveller and IoT services more efficient for consumers, service providers and operators whilst removing the significant environmental and financial cost of discovery and distributing eSIM globally users.
