Hi Tomi,
I'm not in the comms business but have been reading this blog quite avidly for a while now. On the phone subscriptions - I'm carrying 3 mobile phones with me right now and am really finding it a pain, and frankly wish that I could move back towards a single phone - perhaps, with different numbers linked to a single SIM card? Anyway, just a thought, and thanks for always providing illuminating thoughts and insights into the past, present, and future of the 7th medium!

Hi Zim

Great comment, thank you! I've been pushing that idea for the handset makers and the mobile operators for several years now. It is an "obvious" need that many have. There is a very poor partial solution for that in many markets, by which one mobile operator lets you have several phone numbers on one SIM card. But for most consumers, that is not the point of having multiple subscriptions, they typically have network needs ie different pricing plans, family plans, network coverage, an employer-provided phone, etc. So this solution is not really solving much of the need.

The big handset makers would like this, but their big mobile operator/carrier customers will not generally believe in it - they tend to believe that this would both promote churn and disloyalty, and offer too easy a way for customers to switch amongst the networks. Even more so, in all the countries where handsets are subsidised, the operators/carriers feel it is unfair, for operator A to give the customer an expensive phone, which then is too easily used by operator B who didn't supply a handset.

But like you say, I do think this is a long term likely scenario. We see some smaller manufacturers in China already providing this functionality. They are used for example by those who travel frequently, so they keep their primary (Chinese) mobile operator/carrier SIM card in the primary slot underneath the battery, and then if they go to Singapore, they stick a local pre-paid SIM card into the second slot, or in Hong Kong, another local SIM card for there, and so forth.

I do believe it will be coming, but as the big operators/carriers are hesitant (one could say strongly against it, ha-ha), expect this to take several years still...

Thanks for writing

Tomi Ahonen :-)
