ARM wants mobile or IoT devices to include a tiny integrated SIM card:
Every millimeter of space matters when you're trying to build increasingly complex electronics into increasingly tiny packages, and the relatively spacious SIM card has long been an area of frustration for hardware manufacturers. Now, the chip design company ARM may have an answer: an integrated component called an iSIM that's built into the same chip as the processor.
ARM says the iSIM will take up a "fraction of a millimeter squared," whereas the current SIM standard — Nano SIMs — are about 12.3 x 8.8mm in size, not including the hardware usually needed to house them. Not only will that save space, but ARM says it'll more importantly save on costs, too: instead of paying "tens of cents" per card, manufacturers will be paying single-digital cents.

Not forgetting... now your phone can hold an unlimited number of SIM cards.
You can have 20 numbers on one phone.
You can literally add a SIM for every country, network or package deal that you want.
When 4G fails on one of them, it'll just pick up from any other network that offers 4G near you with an appropriate SIM.
As it is, mainstream phones miss out on the "dual-SIM" market which is popular with anyone who travels. With an iSIM, it'll be even easier.
I think the advantages far outweigh the cost of the rare "Oh, my phone is destroyed, I'll have to move my number to another handset" convenience, which can be solved with a web portal.

"Not forgetting... now your phone can hold an unlimited number of SIM cards."
Source required. Who said that feature will be made possible?

I'm sure it will be made possible, but whether it's actually available to customers is another matter.
