One SIM to fit them all

New Apple iPads allow users to choose between data plans offered by different cellular carriers without having to obtain a separate SIM from each. But that's only the beginning as embedded SIMs like the new Apple SIM have the potential to change the way all devices connect to cellular networks. The new iPad Air 2 may be thinner and faster than its predecessor, but the introduction of Apple's own SIM card is the improvement users should be the happiest about. The so-called Apple SIM lets users choose from short-term plans from carriers in the U.S. and U.K. right on the cellular versions of the iPad Air 2 and mini 3. So whenever you need it, you can choose the plan that works best for you - with no long-term commitments. And if the SIM takes off on a larger scale, that and support for 20 LTE frequency bands will make the iPads near-perfect travel companions. But until then, you'll still need SIM cards, and you'll need to make sure you have the right size for your phone or tablet.
