This is a short review aiming to list the most essential points in favor of, and against most popular mobile service providers: Airtel vs. Vodafone vs. Jio vs. Idea vs. Tata Docomo vs. Bsnl. The review is mainly focused based on services provided by these providers in Bangalore, Karnataka.

Airtel

• Airtel is one of the reliable providers in Bangalore, Karnataka, with decent speed and offers.
• Airtel systems are one of the best and have good number of customer care centres across Bangalore, Karnataka.
• But if you are a person who travels more to Kerala, Airtel will disappoint you as there is no 3G for Airtel in Kerala.
• Also, recent offers has put the network and speed with some challenges.

Vodafone

• Vodafone is also reliable provider.
• Though systems and customer care centers are not as good as Airtel, it is still not bad.
• Prepaid offers for Vodafone is usually selective and it depends on your luck on if you will get it.

Jio

• No one can beat Jio in offers as of now, but the network and speed needs to improve a lot.
• Since Jio does not have other bands like 2G or 3G, traveling to remove places and Villages with Jio is a big challenge.
• Jio customer centers are usually present in Reliance Digital stores.

Idea

• Idea has decent offers,
• Idea has the same problem as Airtel in Kerala: there is no 3G band and most of the new 4G offers are difficult to utilize.
• Idea customer service and centers are not the best in Bangalore. 

Tata Docomo

• A decent provider, but without 4G.
• Comparatively lesser number of customer service centers.

Bsnl

• A decent provider, but again without 4G.
• Started giving more aggressive offers recently.
• Comparatively lesser number of customer service centers.
