I recently asked for a demo for Airtel 4g demo.
The first visit was for Airtel dongle & portable wifi which couldn't get good signal strength & they asked if I was interested in ODU (Outdoor unit).
I said yes & the second visit was with the ODU unit. When they fixed the ODu for demo purpose I was blown away as we got nearly 20 mbps download but was in the range if 14-16 mbps & upload of 4-7 mbps.
I would recommend everybody to try the 4g demo & decide whether you want it or not.
4g always gives good data, voice & other internet related functions seamlessly.
