I’m having an interesting issue where i’m sending blank SMS Message (either through at commands or via OpenAT App).
Is there something that I need to do prior to sending? It’s not the sim card that i’m using as I’ve chucked that into my personal cell phone & it works as expected.
The previous sim that I had worked, but I can’t for the life of me remember if I needed to issue any commands (at or openat) to get it working (actually, i’ve tried a couple of sims that send blank msgs).
Any ideas? Any information would be most appreciated
