With so much new technology being developed, we have the advent of what’s called the “e-SIM card.” “E-SIM” stands for “embedded SIM,” or “electronic SIM,” which simply means that the SIM card will come build into the device and not be removable. With all the varying sizes of SIM cards currently available, the e-SIM would be extremely practical in standardizing the use of SIM cards all over the world.
The e-SIM can be programmed with information to operate under other carriers with methods as simple as a phone call to your carrier. This means less hassle for customers when trying to switch service providers or phones, because you wouldn’t have to fumble around with the little SIM card, make sure that you have the correctly sized SIM Card when switching devices, or purchase new SIM cards for each new provider.
For example, if you were to upgrade from the older iPhone, which uses a micro-SIM card, to the newest iPhone ,which currently uses a nano-SIM card, you would either have to pay someone to professionally cut your SIM card down to size for you, or go through the hassle of acquiring a new correctly sized SIM. While this may sound like a relatively simple process to go through, it can be more complicated than necessary–especially if customers were not informed of possible complications with SIM card sizing.
Currently, Apple is trying out their “Apple SIM,” while Samsung has e-SIM cards in some of their wearable technology.
We think that with the advancement of the e-SIM card, a whole new world of possibilities opens up. For example, if the SIM card is programmable, it’s not unlikely that it could render dual-SIM phones obsolete. Who’s to say that you won’t be able to operate both your private and business phone lines on the same device?
