Unable to Tether Unlocked Nokia Lumia 920
I purchased a Unlocked Nokia Lumia 920... Everything works great on it with the exception of I am unable to share my internet access with my own computer. Everytime I try, I get this message.. "Connection not shared.. To enable tethering on the device, go to http://att.com/mywireless or dial 611
I am unable to contact them regarding this problem since I do not use AT&T service. I am on Net10.... How can I fix this?
