The Mobile Data button was greyed out when I tried to check my data usage. At home, I accessed my Public Mobile account online using my desktop and found that I still have plenty of data (I stay home all the time).I will try your suggestions. I hope ...
I had just left home and was about 1 km away, heading to do some shopping in a Toronto neighbourhood when it happened. The Wi-fi button was fine but the Mobile Data button turned gray.Thank you for your info.
