it seems you still have data on your promotion, that will have to end before the 1GB data add-on kicks in.
trun off data roaming and mobile data.
Go to settings - connections - mobile networks - network operators - select manually (usually takes a minute) - Public mobile
Then turn-on mobile data. Hope this fixes your problem
@amohamud What make model of phone do you have? You need to add the correct APN setting before your data will work.
Taking the sim card out and restarting your phone and APN settings will fix this problem 100%. The data should be working right away.

Unfortunately, there is no way to know that for sure. Doing that would only work if this is an APN issues. The Public Mobile account itself or the network are also possible factors.
