I tried these solution but didn't work for me - Is there no option to turn off cell broadcasting messages in HTC Desire 500?

Does anyone really have a proper solution (have experienced).

Also please dont mark this question as duplicate.
Yes. Just remove the SIM from the phone. In the message settings of phone, it will show as disabled. 

Restart the phone, and check and uncheck cell broadcast settings. Then insert the SIM in your phone. It worked for my phone, so hopefully it will work for yours as well.
