i shared phone lines with a person & on my line in my message usage it shows that the blocked number texted my phone but I never received a message or notification from that number I need help how is that possible?
iPhone 15 Plus, iOS 18
Cellular lines cannot be shared between iOS devices, meaning that each device must have its own dedicated SIM card or eSIM to access cellular networks independently. Unlike features like iCloud or Continuity that allow seamless sharing of messages, calls, and other data between Apple devices, cellular service is tied directly to the individual hardware. For example, if you have an iPhone and an iPad, you cannot use the iPhone’s cellular connection on the iPad without a separate data plan — unless you enable a personal hotspot. Even with dual-SIM or eSIM capabilities on newer iPhones, both lines remain exclusive to that single device and cannot be mirrored or shared with another iOS device simultaneously.
