Like a number of other users who have posted here, I had a problem with SMS texts (mainly from BT's fault-repair system) being delivered as text-to-speech. To try and repair it, I tried the recommended methods from the landline SMS-enabled handset - sending "reset" or "register" to 00000, or just sending a text to another subscriber. None of these worked. 5 to 10 minutes after trying to send any message, I get a TTS reply from 00000 saying "There is a technical problem. Please try later". I have tried this on several occasions, so it doesn't seem a temporary thing.
It's hardly a serious problem, but I'd like to know if it's fixable. Is it just that BT Text is a poorly-supported legacy system they don't want us to use, or is there a genuine "technical problem" here?
