I switched to the MyPlan wireless plan last week. Now the MyAccount app says "no Data Plan" when try to see my data usage. The good news is the data is working on the phone. Perhaps the new app needs an update already?
In the month that a person changes their plan, no data usage information will be available and you will receive notice of that in the app. We appreciate your feedback RK and we will be reviewing user experience notes such as this when determining what we can develop in future versions of the app.
Data usage information will work when the new bill period begins so gordon, your bill period must have ended that night and then next day your new bill period started. Quite a nice coincidence :)
