BIGLOBEでんわ is an iPhone app that enables users of the BIGLOBE mobile voice call service to make national calls at half the regular price(*1). The app packs several features that come in handy for anyone who frequently makes national or international calls.

One of the most outstanding features of BIGLOBEでんわ is its affordability. With just 9.9 yen per 30 seconds, users can make national calls without breaking the bank. Moreover, international calls are charged at a flat rate of 20 yen per 30 seconds (excluding satellite phone calls).

BIGLOBEでんわ offers several call pack options to make national calls even more affordable. Users can choose from the 90-minute pack, 60-minute pack, 10-minute flat-rate pack, or 3-minute flat-rate pack. The app also allows users to continue using their existing phone numbers to make calls, and they can call anyone even if they don't use BIGLOBEでんわ.

The app uses a phone line for calls, which means that voice quality is more stable compared to IP phone services.
