How to Turn Your Samsung Galaxy S3 into a Free Wi-Fi Hotspot

Not having internet sucks! We do a ton online these days, from working, shopping, studying, and collaborating, to watching fail videos and endlessly clicking through memes.

But sometimes your mobile screen is just not big enough! So, wouldn't it be cool if you could use your cell connection to get internet on your laptop, office computer, or tablet?

With our Samsung Galaxy S3s, we can share our data connection, and best of all—we can do it for free.

Up until very recently, it was common practice for U.S. carriers to charge monthly fees for this service. Imagine that, an extra charge for using data that we already pay for! We were able to get around this with various tethering apps, but then carriers would come back with updates that prevented those apps from working, and on and on the game went.

Late last summer, Verizon decided it was going to block ALL tethering and hotspot apps from Google's Play Store for its customers. This didn't sit well with the FCC, and they took action. Because Verizon was using a spectrum for its data service that was supposed to allow open access to its network, the FCC ruled it was in violation. They issued a nominal fine and ordered Verizon to not only allow the blocked apps, but to allow tethering/hotspot access at no additional cost.

To turn on the mobile hotspot for Verizon devices, go to Settings -> More Settings -> Slide the Mobile Hotspot to ON -> Press OK if prompted.

Unfortunately, because this ruling only applied to that particular block of airwaves, Verizon was the only carrier required to carry out the FCC mandate (this only applies to newer, i.e. tiered, plans that utilize the spectrum in question). AT&T decided to follow suit by offering free access on their tiered plans. This makes sense; users get to use their data as they see fit, and carriers still charge for data overages if customers are going over their limits.

To turn on the mobile hotspot for AT&T devices, go to Settings -> More Settings -> Tethering and Portable Hotspot -> Slide the Portable Wi-Fi Hotspot to ON -> Press OK if prompted.

Sprint and T-Mobile still charge a monthly fee for tethering. My guess would be that T-Mobile will fall in line with Verizon and AT&T, but the case is a little different with Sprint. While their network has been historically terrible, they are the only carrier to offer truly unlimited data. So if you are feeling sympathetic, you could see why it would make sense for them to charge a monthly fee, especially with its decent LTE network rolling out in full swing.

But still, free is better. Even if you have Verizon or AT&T, you may have a reason for not wanting to use their "official" built-in tethering apps. Forum member Sandy was curious about how to set up tethering on her GS3, and this how-to will walk you through everything you need to get it, if you don't have it already.

How to Set Up Wireless Hotspot (Root)

A wireless hotspot will turn your GS3 into a mobile internet connection that you can use anywhere you get service. Developer TrevE thrilled GS3 users when after months of waiting, a usable wireless tether app was created.

What You Will Need

Step 1: Install and Open the App on Your Phone

Make sure you have "Unknown Sources" checked in Settings -> Security.

Step 2: Set Up Tethering

Once in the app...

  • Press "Menu" and select "Settings"
  • Select "Change Device Profile"
  • Select "Samsung Galaxy S3"

Step 3: Start Tethering

Now, simply hit the signal button and you will start tethering.

  • If you want to change the name of your network, go to Settings and select "Change SSID".
  • If you want to set a password, go to Settings and select "Enable WiFi Encryption".
  • If you want to limit who can use your hotspot, go to Settings and select "Enable Access Control".

That's it!

Remember, unless you have Sprint, you need to be aware of the amount of data you are using so you don't get hit with massive overages. You can check your data use natively on your S3, just go to the main Settings and go to "Data Usage".

Options for Non Rooted Users

  • AT&T and Verizon customers can use the built-in apps.
  • ClockWorkMod Tether is the most stable non-root app option for wireless tethering, brought to you by the awesome devs from CWM Recovery.
  • FoxFi is similar to TrevE's app, but not as stable.
  • Easy Tether Lite - While not wireless, it works very well.

We are battling to register our new Samsung S3 and TAB. Keep on asking for a SSIS number. What and where do we find this SSID?

the same question

When you start the app, push the menu key, change all the default stuff! Change the SSID to something you want, and change the passphrase for it, and make sure the encryption box is checked. Then try adding devices with what you just created. You find the SSID on the device you're trying to add by scanning for wifi networks. Then selecting yours.

I install this and open it up and get a message "sorry, but your kernel does not have all the necessary features for running this application". ??

I have an UN rooted Samsung Galaxy model number SPH L300 and I'm not seeing a root file for my phone. Is there one i can use that is compatible?

although this does work, it will only work a short period of time on the sprint gs3 soon after it will just fail and you cannot use it anymore unless you restart your phone

@david hernandez , how long does it give u wifi before . It stops working

I have MetroPCS and I didn't need to root my Samsung Galaxy SIII. It was very simple to tether my Samsung Galaxy Note 10.1. This was before I got the 4.3 update. It still should be easy.

i managed to share my wifi with an iphone using samsung s3 mini. When my data finished i bought wifi bundles and tried to reconnect with iphone but it seems to not be connecting. is there something that i need to do to activate wifi bundles maybe? because i did not buy data bundles but wifi bundles. Please assist.

Tethering shares your data connection, not your Wifi connection. So while the Wifi bundles can be used on your device, they can not be tethered.

Followed all the way to tethering and it works, however I purchased from Boost and it came without the settings option for hotspot. Is there an app? My laptop will not register a signal from my phone?

I have the galaxy s3 rooted and when I start the tethering it says " tethering started with errors. Check the show log" but when I click on the show log it says file not found. Please help with a fix or any fix for hotspot

I tried to follow your instructions above, so I went to settings, more settings, but I don't have a 'mobile hotspot' on my list. Is there another way to do this?

I have a rooted S3. Downloaded app & followed instructions. The tethering app does not use my data, it connects to available WiFi. My tab can do that. I need my phone to connect to 4G. What do I do?

I have a rooted Galaxy S3, downloaded app successfully but when I click on start tethering, it says tethering started with errors please check show log.

Any suggestions how to come over it?

I have a samsung galaxy s3 of verizon.
My mobile hotspot is not connect error occur in screen is unable to connect at this time try again later.
Any one please guide me to how fix this problem
