I am using BSNL MMX353G Model with version 3.368. For the last one month when I open my internet the blue light continuously flassh indicating registered with UMTS. But the problem is that the connection last for 5 to 10 seconds only and at times even before the web page opens it goes off as the red signal H would disappear after 5 to 10 seconds. It is really frustrating. Can some expert explain the problems?
