About Us

Tienda Siglo XXI is an online retailer specializing in the sale of unlocked smartphones, dual phones, tablets, smartwatches, electronics, computing, and small appliances. We are the official store of the digital newspaper Diario Siglo XXI, a pioneering online media outlet founded in 2003 that, along with the magazine Viajes y Lugares, is part of the Siglo XXI Group.

Since 2012, we have held quality seals from Confianza Online and Trust Ecommerce Europe and since 2014 have been present on leading marketplaces such as Amazon, eBay, Carrefour, Mediamarkt, Fnac, Worten, and Cdiscount, among others. 

The Original Idea: Democratizing Technology

Our project was born in Valencia (Spain) in September 2008 as a result of the international economic crisis, after observing that a large segment of the population was being deprived of access to technology due to its high cost and a progressive loss of purchasing power. In the 21st century society, technology is necessary to meet people's needs and from the start, we believed that no one should be forced to go without what improves their quality of life.

Therefore, our original mission, still valid today, is to offer the world high-tech products of the highest quality at attractive prices, combined with high levels of service, trust, and transparency. We call this mission democratizing technology.
