Nice explanation - and those crucial extra two words of votes being "submitted
and received
" just highlights how stupid the UK companies were to ditch SMS voting when they did (though the short code calling is IMO now a better option anyway).
Not sure I follow.
The issue in the UK was that there was no way of knowing that your SMS would ever be received by the close of voting. Tweaking the Ts and Cs so that you are better legally covered (presumably to avoid refund claims) in this eventually doesn't solve the problem that people vote (and indeed pay to vote) and their vote doesn't count? It covers the contest but doesn't actually fix the underlying problem that votes can potentially be cast, but not counted, does it?
With a phone call, you have a much better idea that your vote will have been received if you reach a recorded "Thank you for voting" message rather than getting an engaged tone.
I've still not seen any proper analysis of how reliable SMS vote tabulation is across the Eurovision nations, so really don't know whether the situation there is the same as it was in the UK, whether the relative volumes of voting SMSs to normal SMSs is different to the UK, whether all countries use the same system as the UK did to avoid crashing the text message network etc.
