There's also the issue that with a lot of networks that do provide SMS notification still (some don't), you have to manually enable it from your account with them (O2 are a major example). So if you're abroad or using an unfamilar or new network / SIM card, you may either not realise you have to enable it or are prevented from doing so due to language barrier.

The fact there's no warning about lack of enhanced notification and the bugs / need to provider enable sms notifications in the phone's settings is awful.

The message is clearly that Jolla would rather people suffer inconvenience and miss potentially important voicemails than either acknowledging or fixing the problem.
