Something I realised too late to do anything about it was that I should have been stocking up on Vs and VIIs during the end of Endwalker. IXs less so because of Island Sanctuary, but I'm sure there were periods there after everyone already had their pentamelded Indagator gear where the price on those got cheap enough that it would have made sense to be buying them up in preparation for Dawntrail's launch.
Oh well, something to plan for this time around!
I created an SMS to Email gateway back in 2011 when data was still expensive on phones and I was trying to see if I could turn an iPod Touch into an iPhone. (I was a poor student at the time, was trying to find ways to save money ๐ )
Basically I had a 3G modem plugged into a Linux server that could receive the messages, a prepaid SIM card with a long life credit expiry, a domain name set up with unknown email address capturing, and some tools to handle the actual SMS part.
At the time I published the scripts I used online and apparently they're still online ๐ This is on Whirlpool which is an Australian telecommunications forum.
