Network congestion and calls drops are becoming common problems among MTS voice customers in Kolkata. The issues can be seen in other circles too.
In an attempt to boost its RevB downlink speed, MTS has deployed three carrier channels for RevB. Each 1.25 MHz spectrum band can add up to 4.9Mbit/s downlink speed. In most circles they have 3.75 MHz spectrum and deployed all three for RevB. It leads to severe call connecting issue for voice customers.
On my personal experience many times in a day I get missed call alerts from MTS, though I was in outdoor. Later people tell me that they called me, ringing was there but actually I did not get any single calls during that time. Not only that often important messages eg. from banks, shopping sites are not delivered to my number.
As I heard that even Airtel users faced similar events while the company were upgrading their 3G network over 900Mhz (Platinum 3G).
For operators data is the future but voice is the present, earning their bread & butter. What do you think - is it a proper ? Drop comments!
