In I At the start, two regional vendors, Reliance Jio and Airtel, have announced their support for the LTE option. This is evident from the official site. According to the website, only one mobile service provider will be available in Sweden and Denmark, so the Apple Watch Series 3 with LTE will only work with a contract of "3" for the time being.
On the Indian side, however, there is a peculiarity. As part of the deal, Jio offers the new JioEverywhereConnect service. This makes it easy to use the same phone number on both Apple Watch and iPhone without incurring additional costs. On the other hand, Airtel customers are allowed to test the tariff first.
With the announcement, additional countries now join the official supporters. The Apple Watch Series 3 with LTE previously appeared on September 22, 2017 only in the US, Germany, Australia, Canada, China, France, Japan, Puerto Rico, Switzerland and the UK. When other countries will follow is uncertain, because it is often up to the mobile operator that the eSIM is not supported. For example, in the US, Apple has already filed a lawsuit to accept the standard among large corporations. It is currently being speculated that other countries will receive the LTE option for the Series 3 at WWDC in June.
