In this article, we explain that when the Internet does not work on your iPhone, then through a 3G / 4G cellular data connection, or via WiFi (or sometimes both).

First we deal with the problem with 3G / 4G connections, WiFi connectivity, or operator. After this, we address the possible solutions of each scenario. We advise you to follow the advice given in the order and join step by step to eliminate the most common people in the first place.

Finally, we follow a series of steps if the problem persists and does not affect Wi-Fi connection or cellular connections, but rather affects the device.

 What is the problem?

First of all, you have to make sure that the iPhone can not connect to the internet in any way. Try doing the following in different ways: Update the mail mail and see if new ones come; Open twitter; Browse some listings in the app store; Open a new web page in any browser other than Safari.

If you can do other things that require internet access, but you still can not open web pages in Safari, then the problem is connected to the iOS browser and not with the iPhone connection.

We also teach you everything you need to know about iOS 12 and its news.

Try clearing your browser history and web data. Keep in mind that this will erase your history and cookies, so you may have to re-enter some information on frequently visited web pages.

The problem may also be due to a random error of some applications, for which you have to try to turn it off and restart the phone. Try updating them all and, in the worst case, install again and install.

Wifi does not work

In general terms, wifi connectivity is usually easier to solve than the one associated with the cell phone. Go to ‘Settings> Wifi’ and verify that the tab is activated in green and that the iPhone is connected to a recognized local network.

You can try simple things, such as opening a web page to check that you have a connection. If you are still offline, then the problem may lie with the network and not with your phone. Check that your router’s connection works through another device.

Wifi, 3G or 4G?

In the event that the internet connection does not work, we should find out whether the problem is due to Wi-Fi connection or 3G / 4G connectivity. This is usually a simple diagnosis to carry out.

Depending on your home WiFi, or the public connection point, where you are, try to make sure it is active and with an active internet connection. Occasionally there is a signal in public places but there is no real connection to the network.

Check data roaming

Although within the European Union roaming has long since disappeared, there are phone models that still offer the possibility of activating it. It no longer makes sense if you move through countries within the European Union and some operators also include it in the United States.

Use of data

Another important action is to check that you have not reached the data limit of your operator fee. Remember that monthly data cycles do not necessarily start and end on the first or last day of the month.

To track the use of data it is convenient to use the dedicated application of your operator, since it is the one that offers you the most up-to-date and faithful information. You can also use the iPhone to put notices or limit of use to your mobile data.

Restart your iPhone

Press and hold the power button located on the top of the smaller iPhone, or on the right side of the larger models, until the message ‘Swipe to turn off’ appears.

Access to ‘Settings> General> Information or About’. If the terminal finds an update, it will ask you to install it. Within this same section, you can check with the operator the version that runs on your phone.
