KnowRoaming's magical SIM sticker auto-detected when your phone was working outside its home territory, switching to local carriers and saving you a bunch of money in the process. What's smaller than a sticker that goes on your existing SIM card, though? No sticker at all. in a collaboration with Alcatel (and TCL), it's announced a Soft SIM software platform, which sounds duller than it actually is. In short, it means no SIM tinkering necessary, and your phone will automatically link up with whatever network it needs to deliver voice, data and SMS services.
