Fonus Inc., doing business as Fonus and Fonus Mobile, is an American mobile virtual network operator founded in 2019 by Canadian entrepreneur Simon Tian and based in Santa Monica, California. [1] [2]
Fonus was founded by Simon Tian in 2019 and is based in Santa Monica, California. The company initially launched a single monthly prepaid plan, in the United States, Canada and Mexico at $30 per month. [3] [4] [5] The data operates on AT&T's cellular network in the United States and affiliate networks in Canada and Mexico, [6] [7] whereas the calls and texts are provided through Fonus' proprietary voice over IP (VoIP) application. [8] [9] [3] [10] As of April 2021, Fonus is one of the top 10 best-rated mobile network operators worldwide on Trustpilot. [11] [12] [13]
In late 2023, Fonus announced the launch of global wireless plans with unlimited data, calls & texts in over 50 countries, starting at US$19.99 per month. [14] [15] . The plans provide 5G speeds worldwide and are available in physical SIM and eSIM formats. [15] Mobile hotspotting, visual voicemail, and Wi-Fi Calling are also supported. [14]
In May 2024, Fonus announced a strategic partnership with Tata Communications, leveraging Tata’s proprietary platform to expand and streamline Fonus’ wireless coverage worldwide. [16]
In March 2025, Fonus launched new wireless plans with expanded coverage in over 100 countries, up from 55 countries previously. Additionally, 5G support is now available in more than 90% of the countries covered. [17] [18] [19] Unlike traditional carriers which impose time restrictions on international roaming - such as suspending service after extended periods abroad - Fonus does not enforce any such time limits on overseas usage. [20] Users may use the service continuously in any supported country or destination, with no restrictions on duration of use. [21] [22] [23]
