How to Change Your APN Settings

Step by step instructions on how to change the APN settings

What are APN settings?

There are various reasons why you may need to change the APN settings on your mobile phone. If you are unsure how to change APN settings, don't worry. The process is very simple no matter what phone or network you use.

The APN is the Access Point Name, which is basically the service provider or carrier that you use to access the internet on your phone. So, why would you need to know how to change APN settings?

Well, you may need to know how to change the Access Point Name if you want to use another mobile network SIM card on your unlocked phone. You might need to look at the access point if you are struggling to connect after you have switched to another network.

You might even need to change the settings to avoid data roaming charges when you take your phone abroad or data charges on your prepaid plan.

In this guide, we'll show you how to change your APN settings quickly and easily.

Changing Your Access Point Name Settings

Whether you have an Android phone or iOS device, the default APN is usually set for you.

Keep in mind that your APN settings can only be changed if your phone, tablet or hotspot has a SIM Card. Otherwise, your carrier might not allow you view your APN settings.

However, it is worth knowing how to change the APN type in case you need to change from your default APN.

Changing the APN Configuration on Android

If you have an Android phone, such as the Samsung Galaxy, changing the APN configuration should be very simple. All you need to do is:

  • Go to the phone setting screen

  • Tap on Wireless & Network

  • Tap the Mobile Network tab

  • Go to Access Point Names

You can then choose one of the pre-set APN options as long as you have an unlocked SIM card. You can also add an APN by getting the APN configuration on the carrier's website. This can then be entered onto your Samsung Galaxy or other Android.

Changing the APN on iPhone

It is also easy to change or add an APN on an iPhone or other iOS device. In order to do this, all you have to do is:

  • Go to your phone setting screen

  • Tap on General

  • Go to Network

  • Go to Cellular Data Network

From there you'll be able to go into the APN settings and change it. Right now, you're probably a little overwhelmed by all the different lines that need information. Don't worry! Below, we're going to direct you to where you can find the specific APN settings for any carrier you plan to switch to.

Accuracy is Important

You can go to each carrier's site to get the information if you want to change your APN setting. This includes carriers such as T-Mobile, Sprint, and the other carriers. However, you need to make sure that the network setting information provided is entered exactly as it is on the APN information for each provider.

You should use upper and lower case in the same places as the carrier has and you should follow the instructions to the letter. For example, let's say you are looking at the T-Mobile APN Settings. The information you need to enter will include fields such as the APN Name, proxy port, server, username and password, authentication type, APN protocol, and APN Type amongst others. Some fields will have nothing next to them while others will contain values.

When you bring the information up, you will see that there are lots of areas that you need to leave blank. It is important that you follow this information and only input the data that is there. So, areas such as username and password, proxy port, authentication type and the server you need to leave blank when entering the information. With information such as APN protocol and other completed fields for the T-Mobile APN, enter them exactly as provided.

APN Settings for Any Carrier

If the APN you want is not already available for selection on your device, all you need to do is go to the relevant page on the service provider website. You will find links to these pages listed below. By going online, you can gain access to the information you need for:

Remember, no matter which of these you are using, if fields such as authentication type of username and password are blank, leave yours blank when entering the data.

Once you have entered the network setting information, you need to save the APN. You can then go back to your Access Point Names or Cellular Data screen (depending on the type of phone you have) and select the network access point you just added to activate it.

If, when adding the new network access point information, you do make a mistake, simply tap on 'reset settings'. This will take you back to the default APN and you can then start over.


As you can see, changing the APN setting on your phone is very simple. Accuracy is the key to success with this process. If you enter any information incorrectly when setting up a new APN, it can mess things up. Everything has to be exact, including any spacing, punctuation, and characters.

Getting the information from the carriers that offer cheap cell phone plans is quick and simple. Once you have entered the information onto your phone, you can simply save it and you're good to go.

The first step in switching to a new network usually involves inputting your IMEI number to determine device compatibility. Check out our step-by-step guide to learn how to find your IMEI number.
