Hi Peter,

Thanks for your comment. This article is based on a decade of experience in the mobile industry, chatting with people familiar with the matter, and advising hedge funds looking to expand in this market.

With respect to Apple’s financial position; I have no expectation that they will go bust any time soon (but then, people said much the same about Enron, Lehrman Bros, etc.)

However, this isn’t just about Apple – my first 3G phone was an NEC, a company now completely absent from the EU mobile market. I have a Sharp GX-10 which I still occasionally use – would I be able to still use it if it had a Virtual SIM?

I completely agree about saving space in complex electronics. If you look at phones released around the same time (SGS, N8, Google Nexus) they all manage to take a full sized SIM (plus micro-SD & HDMI) in a similar size, and with similar specifications.

With regards to changing number – I think it rather depends on the mechanism. If you need to plug your phone into a computer & connect with iTunes – that could be a much worse user experience than SIM swapping. If it’s using an on-screen menu, that could be useful – but depends on the billing mechanism.

At the moment, I can go to any street vendor, hand over a few quid and get a new SIM. Depending on where you are in the world, it can be more complex than that.

I would be interested to know what you think are the advantages or disadvantages of the Virtual SIM.
