No notification for failed subscription

There's no notification for failed subscribed payment, so you lose your data roll-over for months because whatever reason it might cause your filed cards to be failed

Unable to activate sim through app

Tried to activate sim though app. First SIM card timed out and corrupted registration. Needed to find a shop (not all can troubleshoot) to unlock and redo the whole process. Second SIM card a year later, failed to match facial photo to passport, so sent me back to the shop again!
