OneSimCard is a provider of International SIM cards for M2M and IoT. We are able to provide these services in 200+ countries on more than 300+ networks across the world. Our service can offer prepaid and postpaid plans with or without contracts, commitments or monthly bills.

The OneSimCard brand was launched in May 2007 by Belmont Telecom, Inc., a profitable, privately-owned and licensed U.S. interexchange carrier (IXC) founded in 1994. OneSimCard was developed and introduced to the international travel market to solve a growing need to reduce the normally high costs of using a mobile device when traveling across borders.

OneSimCard has grown rapidly since launch and has received numerous recommendations in North American media outlets, including The New York Times, Washington Post, TIME/CNN, Boston Globe, Toronto Star, and an “Excellent” 4-star rating by PC Magazine.

OneSimCard has continued to expand into new markets and now offers outstanding Machine to Machine (M2M) services at very competitive rates.
