Prior I had terrible involvement with airtel 4g dongle, I rang the delegates and said them the issue that its getting 3g-2g flag and speed is awful however its demonstrating 4g. after many calls once a professional comes to re check the arrangement and settings. He did a few settings and it was the same, at long last I sold the dongle and exchanged the responsibility for. As of late in the wake of seeing the TV promotion the test thing, I thought to give an attempt on the 4g sim for my portable, on the off chance that it works fine will purchase a 4g Dongle yet no, it was terrible speed.
