SMS will always be more reliable than data service because SMS runs over the GSM signalling side channel.



Which is irrelevant when GSM is going away and additionally Wi-Fi being more and more common.


Sure.

Aaaand last airport I flew through had a wifi signup which required your phone number.

To send you an SMS.

With a code for the wifi.

So uh...

I'll continue to take my SMS notifications (and emails, which also have nice well-known offline sync properties...) over any more modern appy things, please and thank you.
