HTC / P3400
Idea postpaid sim not working on the device

Hi,

I am Ashish Samarth, from tech mahindra, Sharda center, erandwane pune. I purchased P3400 from Noida, their is used Airtel's prepaid sim. Recently i got transfered to pune and here i tried to use a Idea postpaid sim, but sim is not working properly. I checked with many people, they too are facing the same problem. Can you please figure out the problem and reply back as soon as possible

Device details are:- OS:- WM 6.0

IMEI number:- 35353301653429201

One more thing to be added, airtel's sim is working fine but both Idea and Vodafone sim are not working properly.

Thanks and Regards

Ashish Samarth
