New Delhi, Oct. 11 -- Mobile users travelling from India to the US or vice-versa often experience internet slowdown and complain about losing some premium features embedded in their data plans when abroad. These irritants may soon be a thing of the past. T-Mobile of the US and Reliance Jio are teaming up to launch the world's first global roaming system using the latest and fastest 5G technology, called 5G Standalone (SA). Right now, if you travel between the US and India, your smartphone might lose some of the features or high speeds that come with your plan at home. It's like your premium plan doesn't fully work abroad. But with this new 5G SA roaming, you will be able to keep those benefits and enjoy top-speed service. "We will be announcing the first global standalone (SA) roaming right on the 5G with Jio in a few weeks, and that's really kind of where the customers benefit a lot," Ankur Kapoor, chief network officer at T-Mobile told Mint. "We are pretty confident that before the end of this year, we will actually make this available to all the customers. We still are kind of in the testing phase," Kapoor said. This means that if a user has a special 5G plan with Jio in India or T-Mobile in the US-one that includes perks like faster data and better service-those benefits usually don't carry over when they travel. For example, the specialised plans could include a dedicated gaming 5G plan. In the absence of this proposed 5G roaming arrangement, users are treated like a regular customer when they go abroad, even if they've paid for premium features. With the new system in place, those perks can now work across both countries, so users keep getting the same experience, whether they're in the US or India, explained Kapoor. In India, Jio is on 5G Standalone (SA) network, which runs entirely on 5G technology, making it faster, more reliable, and better for advanced features. In comparison, Bharti Airtel is on 5G Non-Standalone (NSA), which is built on top of existing 4G infrastructure and depends on 4G networks for some functions....
