Ready to smash this thing to pieces 
I had the SMS element working flawlessly on this but now it doesn’t seem to work at all - I’m getting a weird problem where it’s pulling messages from long ago rather than the message it’s actually receiving. Some of them very old indeed. Very similar to this issue, but I can’t seem to fix. I’ve also had it send repeated messages until it burned its way through £10 worth of credit when it was only supposed to text once!
I thought if I incorporated the right AT command (tried the below combinations) I could include an automation to clear old messages but I can’t seem to get the syntax right and just get ‘Not Ack’ back.
It’s definitely not power related - it’s running off an 18650.
Has anyone else had issues like this?
