Bharti Airtel today announced that customers of its network will enjoy free incoming calls/SMS while on national roaming and there will be no premium on outgoing calls, starting April 1, 2017. Bharti Airtel also said that there will be no additional data charges on national roaming. Home data packs for customers will apply even while they roam across India, India's biggest telecom operator said. Airtel's move to lift roaming charges comes in the wake of intense competition in the telecom sector after the entry of Reliance Jio. Though Reliance Jio will charge customers after April 1, the operator has said that voice calls would be free on its network and there would be no national roaming charges.
