I have a Vodafone connection which I primarily use.
The telecom operator is really good when it comes to connectivity.
I get tower connectivity even in remote areas.The customer care service agents are also polite and really helpful.The only problem with the telecom operator is that it is a bit costly.Still, it’s good service makes up for that.
I would recommend Vodafone for professional use or for use by individuals who travel all over the country. Connectivity is really good when it comes to Vodafone.Overall, a good operator.:)
