India telecom operator Bharti Airtel today announced that its 4G network is now available in over 400 towns across Maharashtra and Goa.

Airtel, the second largest mobile Internet operator in India in terms of subscribers, said it added fresh 4G capacity in the 1800 MHz (FD LTE) band to the existing 2300 MHz (TD LTE) network in Maharashtra and Goa.

“We have rolled out a future ready network across Maharashtra and Goa, with enhanced capacity and latest technology. The addition of the second 4G carrier in the 1800 MHz band will enable faster data speeds and better coverage for customers,” said Vidur Rattan, chief executive officer – Maharashtra & Goa, Bharti Airtel.

The largest telecom operator has deployed fresh 4G network capacity in the 1800 MHz spectrum band (using FD LTE technology standard) to supplement existing 4G capacity in the 2300 MHz spectrum band (using TD LTE technology standard).

Bharti Airtel said that the combination of TD LTE and FD LTE significantly boosts network capacity and delivers a superior mobile broadband experience to customers across Maharashtra and Goa through better network coverage and data speeds.

Airtel is offering the complimentary upgrade to 4G. Existing Airtel customers with 4G ready mobile devices can walk into their nearest Airtel Store and switch to a 4G SIM and get one-time free 4G data up to 10 GB.

Airtel’s 4G services are currently available in 21 circles across India.
