I am docomo user from last 5-6 years when I become user in 2011-2012 it is best network in my area providing cheap call rates , good network coverage with data pack is also in budget.
After 2014 it services become really gone wrong call rates are increases , network problem rises and specially data pack are double in price with same data.
Seriously at present time it is really worst network if compare to all the other network.
Another most important it can’t provide 4G & 3G is very slow and 2G only for facebook & whatspp, you can’t play even a youtube video full.
