SonixNet SIM

Looking for low-price and reliable mobile services?

Using NTT DOCOMO’s vast and comprehensive mobile network, SonixNet SIM delivers unmetered and 5GB data plans through Freebit/Bekkoame’s internet connection at the most friendly prices on the market.

SMS and Voice plans are also available at a discounted price.

SonixNet SIM is most compatible with various unlocked SIM-free smartphones or pocket Wi-Fi devices (see here for a full list of tested devices)

Unmetered Data Plans

With unmetered data plans, the monthly data usage (DL/UL) is not accounted for. If your accumulated total data consumption within 3 days exceeds 3GB, your bandwidth will be throttled down to a maximum speed of 200kbps until the 3-day total falls under 3GB.

*With the 5GB plan, after exceeding the limit, the connection speed will be throttled to under 200kbps for the rest of the month.
