#esim postpaid

The topic of eSIM has been brought up again when Smart and Globe announced that it will be using it on more devices under its postpaid plans. eSIM stands for embedded Subscriber Identity Module, or embedded universal integrated circuit card (eUICC). Basically, it functions like a regular SIM card, which authenticates your identity with your carrier, but instead of purchasing the card separately and putting it in your device, an eSIM is already embedded IN the device. In 2016, the Samsung Gear S2 Classic 3G was the first device to implement an eSIM. Apple implemented eSIM support in its newer Apple Watch, iPad, and iPhones. For Android, Google's Pixel smartphones are one of the firsts to be equipped with eSIMs. An eSIM is, as mentioned earlier, an integrated chip. However, while eSIM offers many conveniences, not all devices support it.
