Not only can you receive SMS notifications on your non-smartphone, but you can now respond with your attendance status directly through the message.

The way it works is really simple. When you get a message on your trusty old phone (we all know there’s still plenty of Nokia’s out there), you simply reply with a number:

0 = Not attending

1 = Attending

2 = Other
 

You can also share your ETA if you choose, by using a dot or hashtag after your status:

Example a

[response].[time]

1.20

(Attending; ETA: 20min)

— Or —

Example b

[response]#[time]

1#20

(Attending; ETA: 20min)
