So I do a system update on my phone which is a Zenfone 3. Network doesn't connect after. I wasn't worried at first until I noticed I would get bars for about 5 seconds every 2 minutes or so. I noticed the apn was gone so I tried to re-enter it. I would hit save but it would never save. Then I open it again after trying to create lots of different apns and they all appear at once. Even when one was selected it still didn't work. Not sure if this is a Sim card issue or my phone. Any help is much appreciated!
