Q: personal hotspot option is available for IDEA CELLULAR indian network

Dear I dont find persnal hotspot anywhere in iPhone 4s iOS 8 .without that how I can I change that ....

hi manoj thanks a lot for your post it was very helpful as i was able to use my personal hotspot on iphone 4s ios 8.1 again.

Thank you Manoj. It worked perfectly for my iPhone6.

Thanks Uday Manoj, it worked well for my iPhone 6

This is how I fixed it - Setting-> cellular data options ->  cellular data network

in Cellular Data APN put internet

in Personal HOTSPOT APN put internet

and enjoy Hotspot. This is really revolutionary.

Thanks Kavi and Manoj! Exactly what I needed. By the way, does anyone know if we need to put the "internet" keyword in the "LTE" APN settings as well? What happens if that is left blank?

I have left it blank and it is working fine

Worked like a charm on my iPhone 6S Plus and iOS 9.3.2
