I ported my phone back to Vodafone yesterday, and can no longer receive Google Verification messages. I can still receive ones from my bank. Is this something that will just start working again over time (SMS equivalent of Domain TTL?), or do I need to get someone like JohnR to hit it with a big spanner.

PS: Also holy jeebus I cannot believe that mobile and landline billing services are totally separate in this day and age .. One of the things I was looking forward to was having everything on one account, instead had to dance through a full application, credit checks, and a separate bill.. /facepalm
