Q: Dear All, I m using IPhone 4 and recently updated to 7.1 iOS. After updating , I can not use my hotspot sharing connection. I read all the comments in here and tried everything wrote here but in vain. I called also my operator but no solution. Pls help!

Thank you guys for your replies. I checked this list and indeed my carrier is not there. But, why it was working before very well ? I had no problem. I tried also to downgrad my iPhone to ios7.0.4 but it was not possible. It says an error! Is there any solution to downgrade so can have my personal hotspot back? I do use it a lot really! Or maybe I ll go for android!!! Thank you in advance!

Thank you modular. I was not paying for it. I pay for 3G and by default hotspot was working also same in my old android phone.
