What new rort is this? This evening I received a text message on my Vodafone 'phone which said explicitly "unidentified sender"  (specifically I coud not find any originating 'phone number.) The message contained what appeared to be advertising. I say "new rort" because in the previous several years of having Vodafone mobile numbers, I have never before received a text message which had NO originating number viewable,

Why is Vodafone forwarding such text messages? I do not want to receive UCE via Vodafone text messages, especially from parties I cannot identify.

Is there anything practical to be done to stop this abuse of my 'phone service? Note, the message arrived after Vodafone's 777 customer service closed for the night.
