If you got a new AT&T Samsung Galaxy S II or Skyrocket, you might know that these smartphones have the capability to create a WiFi mobile hotspot capable of providing an Internet connection to 5 WiFi devices simultaneously via tethering. If you do not have a tethering plan though, when trying to enable the tethering and portable Wi-Fi hotspot, you will get the following error message:
Tethering/Mobile AP is unavailable – A Tethering/Mobile Hotspot plan is required to use this service. Please go to att.com/myWireless or dial 611 if you do not already have this service provisioned.
What to do if you don’t want to pay again for the luxury of using the data you already pay for? Well, the mobile WiFi hotspot relies on an application called TetheringManager to see if you have a tethering plan or not. You could delete it, but just to be on the safe side, it is a good idea to “Freeze” it, and make it invisible to the system.
In order to freeze it, you can use Titanium Backup Pro, an amazing tool that resembles a Swiss Army knife as functionality goes. Buy it, you won’t be sorry for it, you can also use it to modify file attributes, backup apps, converting regular apps to system apps and back, etc. Once you bought it, go to Backup/Restore and locate TetheringManager in the list, select it and apply “Freeze” option.
That’s it! You don’t even have to re-start the phone, if you try and enable the mobile Wi-Fi hotspot again, it will just work!
This method probably works on way more devices than just Samsung Galaxy S II, but I only have it to test. You can try it on your smartphone (AT&T) and share whether you were successful or not.
