Are you looking to fix APN Settings on Galaxy S8 for AT&T? If yes, this is absolutely a perfect page for you.

AT&T is a prominent telecommunications company based in the United States. It is one of the largest and oldest telecommunications companies in the country.

AT&T offers a wide range of telecommunications services, including wireless and wired phone services, internet, television, and digital entertainment services.

I remember getting my new Samsung Galaxy S8 under AT&T deals for existing customers and feeling so excited. It was a shiny, powerful phone, and I couldn’t wait to use it for all sorts of things.

But then, I started having this weird problem.

You see, I couldn’t use the internet on my phone, and I couldn’t send pictures or videos to my friends through text messages. It was frustrating because I knew my phone should be able to do all these things.

I talked to some friends, and they told me it might be something called “APN settings.” I had no idea what that was. So, I went into my phone’s settings, just like they told me to.

Then, I found a section called “Access Point Names,” or APN for short. Once clicked on it, there were some strange-sounding words like “MMSC,” “MMS proxy,” and “APN type.” I had no clue what to do with these.

I tried calling my mobile carrier, AT&T, and they gave me some instructions. They told me to change those APN settings to specific values. I followed their advice, but it still didn’t work. I was starting to get frustrated and a bit worried.

Finally, after a few tries and some patience, I managed to get those APN settings right. It felt like a small victory when my phone finally connected to the internet, and I could send pictures to my friends again.

With this article, let me share the APN settings that worked on my Galaxy S8 device and fixed my internet connectivity issue.

So, without further delay, let’s begin.

Every provider has its own APN Settings, which allows you to use mobile data services to access the Internet.

Your device must have appropriate APN Settings based on your provider because you can use cellular data only with the correct APN Settings.
