I want to take the Esp32 with sim800 and turn this into a Hot spot using a prepaid sim card, I have a wireless camera that I can view from my phone, The problem is the camera has to connect straight to internet, It will not work if connecting to internet via landing page, Where I need to place this camera the only wifi is belonging to one that uses a landing page, So I decided to use the ESp32 however it connects but without internet, I have checked the APN by placing the sim card in my tmobile phone, As far as I can tell it is correct. I have also tested to see if I am able to use the data side of the sim card and it worked, Here is the code I currently have
