The Ministry of Telecommunications is set to introduce a service allowing direct voice calls to mobile numbers using Wi-Fi instead of SIM cards. This Voice over Wi-Fi (VoWiFi) service will operate through broadband internet networks, enabling users to make calls even without mobile network coverage, as long as they have a compatible handset and a Wi-Fi connection. While this service will consume internet bandwidth, users will not be charged separately for calls. Operators claim that VoWiFi will enhance call quality and significantly reduce call drops.

In densely populated urban areas, tall buildings and enclosed spaces often cause network disruptions, leading to dropped calls or poor voice clarity. To address this, mobile operators are testing VoWiFi technology in areas like Old Dhaka, utilizing internet service providers' (ISPs) networks. Initial trials indicate improved voice quality and a more stable calling experience. Unlike traditional mobile calls, VoWiFi functions similarly to apps like WhatsApp and Messenger, requiring only internet data.

Shahed Alam, Chief Corporate & Regulatory Affairs Officer at Robi, stated that VoWiFi would effectively tackle issues like call drops. However, Lt. Col. (Retd.) Mohammad Zulfikar, Secretary General of the Association of Mobile Telecom Operators of Bangladesh (AMTOB), emphasized the need for clear regulatory guidelines from authorities. Meanwhile, ISPs see potential business benefits but remain cautious. Emdadul Haque, President of the Internet Service Providers Association of Bangladesh (ISPAB), mentioned that they would support the initiative only if it aligns with their business interests.

The government, recognizing the challenges posed by weak mobile networks, aims to implement VoWiFi swiftly. According to Fayez Ahmed Taiyeb, Special Assistant to the Chief Adviser of the Ministry of Posts, Telecommunications, and Information Technology, this service will alleviate customer frustrations caused by poor connectivity. With over 185 million mobile users and nearly 3,000 ISPs in Bangladesh, VoWiFi could be a game-changer for reliable voice communication.
