Hi frieand I bought Airtel data card for my personal use that is having the Wifi inbuilt feature. Always 5 devices usually connected through Wifi. Although the internet speed is good, m using unlimited pack initially they gives 2 MBPS speed and after the consumption of 10 gb data that reduces to 256 kbps. Connectivity is amazing, easily get connect, till 8 devices can connect without any prob. I always trust on AIRTEL for internet connection, Customer support is also very generous to help towards customer, if wants to add your add-on pack that can be done easily, bill issues or any further issues easily handled by the AIRTEL
