The Apple Watch Ultra 3 will have satellite service that lets you send texts, according to Bloomberg sources. Much like recent iPhones, the toughened smartwatch will use this as a backup for when cellular service or Wi-Fi isn’t available. That would fit the Ultra’s target demographic of hikers, divers, and others who can’t count on terrestrial wireless networks. Apple might also move beyond LTE data with the Watch Ultra 3, the insiders say.
