There are a few potential reasons why you may not be able to remember your network connection on your iPhone. One reason is that your iPhone may not be able to access the network if it is not connected to the network. Another reason is that you may have deleted the network connection or changed your network settings. Finally, if you are using a cellular plan that requires you to have a certain number of minutes per month, your iPhone may not be able to access the network for a certain period of time.
