Hi friends I using idea operator for last 3 years but I never face any problem with this network idea is providing 2g, 3g, and 4g services. 2g services are very good but 3g is adequate.where as 4g services does not reached the LTE data speeds.the signal coverage is very good even if we go to villages we can find signals.but the cost of services is very high call and data services are high compared with other operator but it is same as airtel. due to the jio evect now the idea is giving new offers in order to hold there costumers.if the call and data rates are decreased this network will become one of the best operator.
