NTT Docomo to remove 3-day 1 GB limit on LTE data

All  of the Japanese carriers, in addition to having a monthly cap on data usage, also implement controls on short-term usage. This is because they lack the infrastructure to support an enormous instantaneous demand. In the past with other carriers, this has caused a tremendous amount of confusion due to inconsistent and improper communication to customers regarding these throttles. (Actually, it was probably because this particular carrier was making things up as it went along.)

To make matters worse, these throttles can be ridiculously implemented, where if you exceed a certain amount of data over a certain period of time, you get throttled, but not immediately. Instead, the throttle goes into effect up to 2 months later. That has nothing to do with network management and is purely punitive. I'll be glad to see these go.

Docomo Repeals 1 GB Limit


Docomo's limit was 1 GB over 3 days for Xi LTE data. Exceeding that results in a drastic speed decrease on the following day.
Xiのエリア拡充が進み、速度制限を無効にしても、お客様が快適に利用できる環境が整ったため
With continued expansion of the Xi coverage area, we can now provide a good user experience even without speed restrictions.
So Docomo will remove the restrictions. Yay! (There's no word on when, however.)

The 366MB 3-day limit on FOMA data will remain.

What about Softbank and KDDI?


Softbank and KDDI have commented that, at the present time, they have no plan to also remove their data limits. So that means they are now scrambling to figure out how to remove their limits, because once one Japanese carrier does something like this, they all have to follow suit or get left behind. I imagine that KDDI will be the first to announce the removal, followed by softbank. When Softbank finally announces, it will be accompanied by a huge amount of noise and BS.
