The network has stocked up on the new SIM standard, which is likely to make its debut in the new iPhone, which is all-but-certain to be announced in San Francisco on Wednesday evening.
Vodafone made the announcement in a post on its official blog, which Pocket-Lint points out has now been removed as nano-SIM-enabled devices are not yet available.
The post from Vodafone comes a week after T-Mobile Germany informed retail partners that the next-generation of SIM technology will be winging its way to them.
Handle with tweezers
"They're so slim and tiny you might only be able to handle them with tweezers - but imagine the extra space the new nano-SIM card frees up inside your handset," Voda's post read.
"The first devices have now been announced – and Vodafone has now got 500,000 of the new 12.3 mm x 8.8 mm nano-SIMs in stock."
We'd say there's a very good chance Vodafone will republish this post as soon as the iPhone 5 is announced in tomorrow evening.
