Apple has just announced the new Watch Series 3 with cellular. It can make and receive calls, even without the iPhone nearby, using the same number as the iPhone. You can also get messages and updates from third-party apps, as well as stream Apple Music directly through the Watch. The sad news, however, is that Series 3 with cellular will not be coming to Singapore at launch. This is likely because the Watch uses an e-SIM and not a physical SIM card, which entails working with a local telco.
