Jio Announces VoLTE Based International Roaming Services in India

By November 20th, 2018 AT 8:02 PM

Reliance Jio, which is India’s first LTE-only network today announced the launch of VoLTE-based inbound International roaming service between India and Japan. Jio is the first telecom service provider to launch such service in India. With this service, international roamers will be able to enjoy roaming services on Jio’s network including HD voice and 4G high-speed data. Japan-based KDDI Corporation is the first international mobile service provider to avail of Jio’s VoLTE calling and LTE data international roaming service which provides international travellers with access to high-speed data and voice services on Jio’s all-IP, 4G-only network.


What is VoLTE International Roaming Service?

First of all, let’s take a look at what VoLTE International Roaming service means. Jio has inked a deal with Japan’s KDDI Corporation which is a telecom service provider in the said country. It’s basically the same roaming agreement deal between two telcos, and Jio is giving a fancy name to it. But Jio being a 4G-only operator, the telco is calling it as VoLTE International Roaming Service.

With this new arrangement, international travellers will be able to experience Jio’s all-IP network when they travel to India. That said, users of KDDI will have to activate a international roaming plan before travelling to India.

Reliance Jio is focused on delivering the best data and voice experience to all of India and those who visit India. We welcome KDDI customers to Jio as the first international VoLTE and HD roaming users in India,” said Mark Yarkosky, Reliance Jio in a press statement.

Jio Has Over 96% of LTE Coverage in India

Reliance Jio has been setting benchmarks in the network coverage section for a while now. According to a recent report from OpenSignal, Jio has over 96% of LTE coverage in India, while the LTE coverage of other telcos is less than 80%. Furthermore, Jio has been ranked as the fastest mobile operator by the Indian telecom regulator Trai, but OpenSignal has often rated Airtel as the fastest telco of India.

Furthermore, Jio committed that it will turn India into the world’s largest consumer of mobile data and has already catapulted it to the 9th largest mobile operator in the world with over 252 million subscribers within two years of launch.

Look at the speed of JIO’s network at my place, in Jamnagar city of Gujarat today morning around 10:45

Phone is Redmi Nofe 5 Pro, so no CA on the phone.


u r sitting in reliance jamngr refinry which come under jio tower….hahahah


Bhai mere, Reliance Jamnagar Refinery is 30 kms away from Jamnagar city.



I get similar speed (50 Mbps) on a low end phone as well.


Jio prepaid worked seamless in Singapore without any pack or activations. Did not miss any incoming messages. It latched to M1 telco on 4G with volte and sometimes 3G.
