Based on using the various solutions in this space as a player, text messages and mobile notifications are the norm (folks that don’t install the app will still need sms or similar).
I've integrated with Twilio. I pay a whole bunch of money every month for sending SMSs. And then recently they made me jump through a bunch of regulation hoops. Had to give them all my business documents.
So even if OP does all the work of integrating it, I assume OP isn't going to pay the fees for you, so then you have to create your own Twilio account and jump through the same hoops.
Hmm is there really a benefit of using SMS rather than email? Nowadays everyone just gets email notifications on their phone anyways right? Depending on the provider, you might not receive the notification as instantaneous as with SMS, but it should still arrive quickly. And emails are cheaper (or even free) to send than SMS.

Not everyone does. It's a typical 80/20 problem (the 80% being those who use the technology that's easy to develop for, the other 20% being the hard part). 80/20 not being the exact numbers, obviously.
That being said, you certainly don't _have_ to cover more than one way of sending notifications, but that's a decision to be made and the consequences acknowledged.
