On Wednesday, Telstra announced they had “identified an issue with some older Apple devices connecting to our network”. Older iPhones models that have been updated to Apple’s latest update, iOS 16.7.13, including the iPhone 8, 8 plus and iPhone X, are being investigated. “We’re working on this as a priority with Apple and will share updates as we have them,” a Telstra spokesperson said on Thursday. Other network carriers, including Optus and Vodafone have not been affected and neither have more recent iPhone models using Telstra. “This is an important issue for affected customers — Telstra and Apple advise they are working to fix this urgently,” the spokesperson said.
