About Us

Telestial.com, powered by OneSimCard, provides convenient and cost-effective telecommunications services to businesses and recreational travelers across the globe.

Telestial has partnered with local carriers around the world to provide you with the lowest domestic rates available and, in many cases, highly economical international long distance rates. International roaming SIM cards from Telestial are compatible with GSM (Global Services for Mobile), the most widely implemented wireless standard outside of North America.

Telestial was founded in 1999 by a former telecommunications consultant. As a committed globetrotter, he started the company after a 10-month sojourn in Southeast Asia and the Indian subcontinent. There he found his calling choices were of poor quality and, often, outside his budget. Although cell phones are ubiquitous from India to Indonesia, a one-minute international call could cost more than a night's lodging. This frustration led to the creation of Telestial to offer fellow travelers the same telephone access and price, as the locals, at international destinations around the world.

Since December 2017, Telestial has been powered by OneSimCard. The new platform brings even more worldwide coverage at affordable rates, as well as 24/7 customer support. 

Telestial is looking forward to providing the telecommunications solutions that will make your trip safe, successful and economical.
