Airtel is one of the biggest cellular networks in India. It’s services like My plan and Airtel Money is quite popular. Airtel provides some of the very good internet speeds and with its solid coverage, you will rarely have any connectivity issues when travelling. But it is a bit pricey as compared others but their services are worth paying that little bit extra.
Now due to increased market competition, they are offering data and voice calls at an affordable price. They are battling out with some heavy competition by offering some great internet offers.
After complete acquiring of Telenor. Airtel has opened its wings to give a stiff fight. Airtel will get Telenor services which are available in 7 circles, serving more than 55 million customers at very low internet price and call rates. This will boost the Airtels customer base and also the coverage network.

The best part of BSNL is it offers 2G and 3G at the same price but its net speed is substandard with very poor internet connectivity. It has not acquired 4G rights for PAN India.

With solid coverage and great value for money, BSNL is the best Bang for your Buck but its poor internet speed and connectivity could be a critical factor.

#3.  Idea

Idea cellular provides good coverage in urban and rural areas. It provides good internet speed but generally has some expensive tariff plans. You may face few issues of call drops and low signals while travelling but still Idea is a very good choice when it comes to net speed and customer service.
If you are looking for something with good speed and stability with good rural coverage then Idea is for you. 
Note: Idea and Vodafone are in conversations to coalesce, this merger could turn out be the biggest mobile cellular unit in next 3 to 4 years.

  • Good internet speed
  • 4G Rollout

  • Low signals

#4. Reliance Jio

Reliance Jio Infocomm is said to be world’s biggest startup with over Rs. 1.5 Lakh Crore invested in this mega project. The company has acquired rights for 4G services in all circles of the country. Of course, it is too early to talk about the success of the project but for sure Jio has created ripples across the telecom sector of this country.
Jio can be said to have created what is called Telecom Revolution by offering free voice calls, no roaming charges, unlimited night data and a free subscription to the bunch of useful apps like JioTV, Jio Music etc along with other exciting offers.


Under Jio Prime membership it offers extra which is surely exciting the customers to avail the free benefits by Jio. The prime offer is a good strategy to keep the customer base and excite potential customers to buy their service.
Jio for sure has given head-to-head competition to the already established telecom networks.

  • Good 4G Speed
  • Free subscription to Apps
  • Low tariff plans rate


  • Poor voice quality
  • Call Drops

#5.  Vodafone

Vodafone used to be one of the weakest nationwide mobile carriers but with time, this carrier has shown its potential. The services provided by Vodafone are good and so is its 3G & 4G speed which is very high as compared to others. But it’s rural coverage is poor and is, therefore, suitable mostly for urban areas.
With average network coverage and the high price, it is liked only by masses but given that its speed is awesome, it gives great user experience for any general internet user.

  • Excellent internet speed
  • Good coverage with excellent stability in urban areas
  • Appreciable price
  • 4G Services
  • Good customer care service


  • Not for rural areas
  • Do not have countrywide coverage

 #6.  Tata DoCoMo

Tata’s collaboration with the Docomo telecom of Japan gave birth to Tata DoCoMo. Docomo’s weakest attribute is its network which is limited only to cities and towns. If you live in an urban area, you’re probably safe, but stepping out too far into the suburbs will cause connectivity problems. But it offers its 3G services at prices which are very low as compared to others. It also offers other value-added services at fairly low cost.
If you live in an urban area than Docomo is meant for you giving you a top-notch service with some cheap tariff plans.

  • Low internet prices
  • Excellent network of towns and cities
  • Good internet speed
  • Exciting offers


  • Not recommended even when travelling
  • Extremely poor rural coverage
  • Unstable signals in many parts of the country

#7.  Aircel

Aircel may not have a PAN India network but its presence in limited demography in southern and eastern India with lower customer base has made it favourite one because of low congestion in the networks, excellent customer support,  low prices and good offers.
It provides 3G and 4G services at affordable price and super high speed. A survey conducted by Mint-instaVaani ranked Aircel as a top cellular network in India better ranked than Airtel and BSNL but looking at its limited presence they love to be customer-centric organisation.
