In recent times, some users of the iPhone 17.5.1 version have reported experiencing occasional cellular connectivity issues, where their devices would display normal signal and 4G/5G icons but fail to establish a connection. To resolve this problem, users have found it necessary to manually switch to airplane mode and then switch back to normal mode before they can regain connectivity. This inconvenient workaround is not ideal and may cause frustration for users who rely heavily on their cellular connections.
