To appreciate the service, one must first understand its fundamental difference from Over-The-Top (OTT) applications like WhatsApp, Viber, or Imo. OTT apps require users to log into a third-party platform, use a separate identifier, and rely on the app being active on both ends of the conversation. Wi-Fi Calling, in contrast, is a native telephony standard (governed by GSMA specifications) embedded directly into the smartphone’s operating system and the carrier’s IMS (IP Multimedia Subsystem).
Looking forward, Wi-Fi Calling is a foundational element for Grameenphone’s 5G strategy. As 5G networks utilize higher frequency bands (e.g., 3.5 GHz and mmWave) that are even poorer at indoor penetration, the need for seamless Wi-Fi offload will become critical. Furthermore, as GP rolls out converged billing systems, we may see a future where the distinction between “Wi-Fi minutes” and “cellular minutes” disappears entirely, replaced by a unified “data voice” metric. grameenphone wifi calling
