Data Docomo does not Have the Good Network all over India.
I Port my Number From Vodafone to Docomo just because Docomo was cheaper than Vodafone but the network Disturbance is very high.
When I am in my room and someone tries To call me it is always unreachable.
Customer Service is Good but Not so good As other Mobile Operators.
Chargers are at reasonable rates but I dont Prefer you to port Or buy a Docomo Network as You can face the Network Issue.
