I have an HTC Windows Phone 8x that was once locked to the Rogers network. I unlocked the phone so that it could accept a Koodo SIM card. The phone is running Windows Phone 8.1 operating system.
I configured the internet APN and MIMS such that the phone calls, messaging, picture messaging, and data connection all work perfectly. I am currently up to date on paying my phone bill.
However, whenever I try to turn on internet sharing (tethering), I get the following error message:
"Connection not shared
There's no mobile data connection to share at the moment. Check your mobile settings and signal, and try again."
This message occurs despite the fact that I have a strong signal, and that the mobile data is working fine on the phone.
Why is this happening?
This might be a red herring, but it could be an important sign, so I will tell you this. Sometimes when I wake up the phone, I find that there is no service, even in areas when I always get a strong signal. When these episodes occur, service restores to maximum strength within 10-15 seconds of awakening the phone. This happens maybe 1 in 10 times that I wake up the phone. This never used to happen when I was on the Rogers network.
