In what can be seen as the first signs of a rate war after Reliance Jio announced its tariff plan, the country's largest telecom operator Bharti Airtel on Monday said that from April 1, it will abolish national roaming charges and reduce international roaming charges by up to 90%.
National roaming charges account for only 3 - 4. 5% of the company's revenue while international is even smaller, but while the former is more of an inconvenience to subscribers, the latter may give huge bill shocks to unaware customers who have not subscribed to some package.
