Before you start troubleshooting, verify and ensure that your account status in good and that all your services are active. Carriers usually impose temporary disconnection or soft disconnection to accounts with unsettled issues on bills and other account-related matters. When your account is in a soft disconnect state, your outgoing services are not available as they’re temporarily disabled.

Restart / Force restart

It is also worth noting though that all your current settings for Wi-Fi including network passwords will be erased in the process.

Update iOS

Network errors can also be attributed to software bugs from an app or iOS itself. Minor bugs are usually rid of by performing a soft reset or forced restart but others are just tough enough to withstand those methods. Installing a new iOS update can be a potential solution. Aside from new features, software updates also contain bug fixes to address existing issues on iOS devices. If you haven’t already, then you should consider updating to the latest iOS version and see if that’ll take care of the problem.

If you have access to Wi-Fi, you can check for (OTA) software update by going to Settings-> General-> Software Update.

An update notification pops up if an update is available for your iPhone. Before you proceed with the update download and installation, back up your iPhone data for safekeeping first.

If you don’t have access to Wi-Fi, then you can use iTunes on a computer to check any available software update for your iPhone 7 Plus.

Remove and reinstall SIM card

No service and other network signal issues can likewise be attributed to a dislodged bad SIM card on the iPhone. To ensure that this isn’t the root cause, try to remove and reinstall your SIM card. Here’s it’s done:

  1. Power off your iPhone completely.
  2. Get the SIM card eject tool ready. If you don’t have it, then just take a small paper clip, make it straight and then use it instead.
  3. Locate the SIM tray on the right side of your iPhone.
  4. Insert the SIM eject tool or paper clip into the small hole.
  5. Then gently put it until the tray pops out.
  6. Remove the SIM card from the tray.
  7. Check for any signs of damage. If there’s none, then reinstall the SIM card.
  8. Insert the SIM card into the tray and make sure the notched corner aligns and the gold contacts facing downwards.
  9. Gently push to reinsert the SIM tray into the iPhone.
  10. Press in on the tray to lock it into place.

Or else, take your iPhone to an authorized service center and have it diagnosed by a technician for possible hardware damage.
