This guide will go over everything you need to know about changing Galaxy S8 APN settings. Which are often required in order to use a phone on carriers other than where it was purchased.
APN stands for “Access Point Name” and is essentially a gateway to carriers. It gives your phone the necessary information to communicate with AT&T, T-Mobile and others. Everything from 4G LTE to sending text or picture messages.
This is usually done automatically when you put in a SIM card, but it doesn’t always work. As a result, owners will need to find and manually configure the APN settings themselves.
How to Change Galaxy S8 APN Settings
The steps to find the correct menu in settings may vary slightly depending on which carrier the phone came from. A full set of instructions with images as a guide are below.
- From the Home screen, tap the Apps icon (or pull down notification bar and hit gear-shaped Settings button)
- In Settings go to Connections
- Choose Mobile networks
- Then select Access Point Names
- Choose the necessary APN from the bullet list or if your carrier is listed. If not available, tap ADD
- Input new APN settings provided by your carrier of choice
To reset your APN settings, tap the Menu (3 dots) icon and then tap Reset to default.
In this menu owners will see the default APN option on their phone if a SIM card has been installed. Tap the ADD button in the top corner to start. You’ll see a lot of weird things like name, proxy, mmsc, port, and protocol. It sounds confusing, but you don’t need to know what they mean. All we need is the information from any specific carrier.
Shown above is the APN settings menu. I’ve gone ahead and hit “add” and started adding the required information for T-Mobile’s APN settings. Input all the required lines of text, skip where it says “not set” then select the three dots at the top and tap save.
Now your AT&T or Verizon Galaxy S8 can communicate with T-Mobile cell towers and work as it should.
Below we’ve found the latest T-Mobile APN settings for 2017. Look for similar information for the carrier you’re interested in using.

- Tap MORE > Save
Simply enter all of the above information into each line under the APN settings menu on the Galaxy S8. Once you hit save, go back and select the newly entered APN configuration and reboot the phone.
To ensure everything worked right try making a phone call or sending a text message. If it doesn’t, double check for any mistakes and try again. Users can also call their carrier of choice to confirm the APN settings are correct.
