How to Fix Network Lost Error on iPhone

Are you getting the Network Lost error on iPhone and don’t know what to do?

No matter what iPhone model you use, a network lost error is what most of us have been through. The message pops up every few minutes, indicating that your device fails to establish a strong internet connection.

Consequently, you’ll be unable to use all features and apps whose services rely on a network connection. These include SMS and MMS messages, calls, maps, and other applications requiring Wi-Fi or a data network to operate.

Mostly this is not an iOS-related issue but rather a carrier problem or a fault in your device. Fortunately, you can rectify the issue through generic and straightforward solutions we’ll be explaining in the forthcoming sections. For times in which you encounter the same problem, this guide will come in handy.

Continue reading to learn about the many options you have to fix this error!

1. Check Your Coverage Area.

When your iPhone keeps losing network connection, the first thing you may want to do is check if you have the coverage for Wi-Fi or mobile data in your current location. And if so, whether the signal strength is stable enough.

To do this, check if the Wi-Fi bars are full or if the network service bar doesn’t have a cross next to it. If any of them is between one and two bars, it indicates a weak signal strength and a probable cause why your iPhone is continuously disconnecting from a  network.

A simple thing you can try is to restart these services and see how that goes. For that, follow these steps below:

  1. First, go to Settings.
  2. Then, tap on Wi-Fi or Cellular, depending on what you use.

  1. Turn the Wi-Fi or Cellular Data toggle off and on, then see if the problem is resolved.

Moreover, it’s always best to restart your iPhone before turning your Wi-Fi or mobile data back on.

2. Ensure Data Roaming is On.

If you’re traveling internationally, chances are your original carrier service isn’t available in that region. This is why you need to turn on Data Roaming. This feature allows you to hop onto another cellular network to access internet services while the billing still goes to your original provider.

Here are the instructions you should follow to turn on Data Roaming:

  1. To begin, head over to your Settings app.
  2. Now, tap on Cellular.
  3. From there, go to Cellular Data Options.

3. Ensure Airplane Mode is Not On.

Another factor you may want to check to get rid of the Network Lost error on iPhone is the Airplane mode. When this is enabled, your device won’t connect to the internet and will fail to load information.

Here’s what you should do:

  1. Begin by launching the Settings app from your Home screen.
  2. Then, check the toggle next to Airplane Mode at the very top. If it’s green, tap on it to disable the feature.

4. Connect to Cellular Data Instead of Wi-Fi.

A fix that works in most cases is to turn the Wi-Fi off and connect the mobile data instead. All devices usually prefer connecting to Wi-Fi over a data network. 

Therefore, if you have an unencrypted Wi-Fi network nearby, your device will automatically connect to that. This network will also provide services to multiple other devices for obvious reasons.

To prevent this, you need to turn off Wi-Fi. Here’s how to do it:

  1. Open Settings on your iPhone.
  2. Then, go to Wi-Fi.
  3. Lastly, turn the Wi-Fi toggle off, and you’re good to go.

5. Allow The Network To Switch Automatically.

If you’re going from an urban location to an area with remote services, the chances are that the network you’re currently using will not be available there. For this reason, you may want to switch the Network Selection to automatically so that you don’t face a Network Lost error on iPhone.

Follow these steps to do so:

  1. On your Settings app, go to Cellular.
  2. Then, tap on Network Selection.

Carrier settings update brings new and improved settings that boost your device’s ability to maintain increased connectivity with nearby wireless networks. The update is released by your carrier provider to enhance carrier network and performance along with related settings.

Some carrier updates are mandatory and let you know after its installation is completed. Otherwise, you’ll have to check for one manually. Before starting, ensure you’re connected to a Wi-Fi or cellular network.

Then, follow the steps below:

  1. Start by going to the Settings app, then tap on General.
  2. Next, tap on About.

8. Re-Insert The SIM Card.

Sometimes, the Network Lost error may occur due to a damaged or improperly placed SIM card. To fix it, either take it out from the SIM tray or put it back in or ask your carrier to provide you with a new SIM card.

To follow the former option, you’ll need a paper clip or a SIM-eject tool to push in the hole next to the SIM tray. Remember not to use too much force as that may result in further damage to the iPhone.

9. Contact Your Carrier.

If you believe the issue is in your chosen carrier service or your account and nothing else, it’s advisable to contact them immediately as they’re the only ones with complete access to your account details.

While doing so, you should verify that your account is active, no data outage has occurred in your area, and that your device is not blocked from receiving data signals. If you don’t know where to contact your carrier provider, use Apple carrier support to look for your carrier’s page.

If the problem isn’t in your account or your subscribed network service, it’s time to contact Apple Support.
