Viamo launched its 231 Voice Platform in Ghana on August 7, 2026, delivering artificial intelligence to feature-phone users through a toll-free service on MTN Ghana that works without an internet connection, Citi Newsroom reported September 9. The platform went live supporting six languages: Twi, Ewe, Hausa, Dagbani, Ga, and English.
The Ghana deployment represents Viamo's fourth MTN country platform, arriving at a moment when much of Africa remains locked out of internet-dependent AI tools. The company said it has now brought offline AI to 13 countries across 10 languages, with Nigeria slated for 2027.
The mechanics are straightforward. Users dial a toll-free number on any mobile handset, including basic feature phones that predate the smartphone era, then speak questions in whichever language they prefer. Viamo's Ask Viamo Anything (AVA) system processes the call and returns spoken answers, no data plan or app download required, according to a company post on LinkedIn dated August 24.
"At its simplest, the Viamo Platform is a nationwide, toll-free voice engagement system that works on mobile phones, including basic feature phones... and does not require an internet connection," Viamo wrote.
Organizations can integrate their own vetted knowledge bases into the infrastructure. Viamo said 231 can handle use cases spanning health information, education content, agricultural advice, financial inclusion programs, public announcements, behavior-change campaigns, beneficiary feedback loops, and citizen engagement initiatives.
Distribution Through MTN's Network
MTN Ghana supplies the national backbone for the toll-free voice channel. The Ghana launch follows earlier MTN collaborations in Liberia, Zambia, and Rwanda, building what amounts to a multi-country infrastructure play.
"We want NGOs, government and the private sector to see 231 as infrastructure they can plug into — to reach more people, listen to communities and make their programmes and services more inclusive," Dr. Nii Lante Heward-Mills, Viamo's Country Director for Ghana and Liberia, told Citi Newsroom.
The August 7 launch event unfolded at Google's AI Community Centre in Accra. Panelists included Edmond Moukala from UNESCO, Ronald Tagoe from mNotify, Brendon Gonouya from AyaData, Winifred Cobblah from Ghana Health Service, and Ato Ulzen Appiah from Academic City University.
A Company Built on Inclusive Tech
As of September 9, 2026, Viamo operates in 23 countries across Africa, Asia, and the Middle East. The company claims its platform supports more than 70 languages globally, though the exact breakdown wasn't disclosed.
The company evolved from VOTO Mobile, which started in Ghana before merging with Human Network International in 2017. The Global Innovation Fund led a $1.5 million Series A round in 2021. More recently, the Gates Foundation awarded Viamo $4.3 million in funding announced in 2022.
In August 2024, Telecel Ghana partnered with Viamo to relaunch a free "321" information service for feature phones, offering Telecel subscribers health, agriculture, education, and financial literacy content.
Other voice-AI providers targeting African languages include Indigenius.ai, Equallyz.ai, Africall, and Umbaji, which deploy across interactive voice response (IVR), public switched telephone networks (PSTN), and WhatsApp channels. Abena AI offers a voice assistant supporting Twi, Pidgin, and English, but it requires a smartphone app, limiting its accessibility.
"Conversational AI is not a luxury for the elite; it is a lifeline for the underserved," Edmond Moukala, UNESCO's Country Representative for Ghana, said at the August event.
The statement captures the underlying tension in AI's global rollout. While Silicon Valley companies race to deploy ever-more sophisticated chatbots and voice assistants, hundreds of millions of people in emerging markets still rely on feature phones and intermittent connectivity. Viamo's bet is that voice-first, offline-capable AI can close that gap, perhaps more effectively than waiting for universal smartphone adoption.
