4G LTE

  • NO CAPS or THROTTLING
  • FASTEST SPEEDS AVAILABLE
  • DIRECT CONNECTION / NON-MVNO
  • NO TOPPING OFF REQUIRED
  • LARGEST COVERAGE AREA IN JAPAN

SPEED: Our 4G service from DoCoMo is a direct connection to the network with speeds currently as high as 375Mbps.

COVERAGE: NTT DoCoMo provides coverage in all major cities, rural areas, on bullet trains, and recently on most subway lines.

CAPS: There are no daily, weekly or monthly limits (Caps) on the amount of data which may be transferred using our sim cards or mobile devices.

THROTTLING: Also, we do not throttle (speed reduction) after a data limit has been reached. Thus, there is no requirement to add data (Top-off) which may be inconvenient when on the move in Japan and access to the internet is necessary.

MVNO: Most other companies use MVNO's (mobile virtual network operators) which are 3rd party networks or sub-carriers which piggyback off the main network. The speeds provided are determined by the MVNO's backbone and backend capacity. So it's important to confirm the data speeds and limitations in advance of choosing your service in Japan. For example, some MVNO's limit speeds to 75Mbps, the life of the service, the daily and overall data included with the plan.

3G/UMTS

  • TRUE 3G UNLIMITED DATA
  • NO CAPS or THROTTLING
  • FASTEST 3G SPEEDS AVAILABLE
  • DIRECT CONNECTION / NON-MVNO
  • LARGEST 3G COVERAGE AREA IN JAPAN

Similarly to our 4G, our 3G service from DoCoMo is a direct connection to the voice and datanetwork with speeds currently as high as 14Mbps.

DoCoMo's 3G service continues to provide True Unlimited Data for our users. There are no daily, weekly or monthly limits (Caps) or throttling.

Because most assets are being used to expand the 4G network, speed and service is not expected improve in the future.

Note: Since visiting users roaming from outside of Japan are predominantly using the 3G network many metropolitan areas have noticed increased network congestion causing slower 3G data speeds. Also, more smartphone video and audio application usage has added to the congestion.
