Hi, this is Wayne again with a topic “eSIM and iSIM Explained”.
For many of us, switching your phone service over to a new phone is pretty straightforward. You take the SIM card out of your old phone. You pop it in your new phone and boom you’re better, but we’re starting to see more and more phones, especially at the high end, forego the physical SIM card altogether in favor of e-sims. Basically, a Sim chip. That’S soldered directly onto your phone’s motherboard.
If you’re not sure exactly what a SIM card does. It contains a small amount of data that identifies you to whichever mobile network the card is meant to connect you to this way. The mobile carrier knows that you have an active subscription and subsequently allows you access. Okay come on, hence the reason you pay for a local SIM card when traveling internationally, as at that point you’re trying to connect to a different network than whatever you’re using at home. Of course, with the fact that space inside the typical smartphone is at a premium, these days think about the well-publicized removal of the headphone jack courage. It isn’t surprising that phone manufacturers would want to get rid of the relatively large physical Sim slot and replace it with something much smaller.
A standard. Physical, nano SIM card measures about 12 by nine millimeters, but e-sims start at six by five millimeters and get even smaller from there. But how exactly do you change your carrier? If you can’t swap out a physical Sim, there are actually several ways to do this. A carrier that supports esim can give you a QR code, making switching services a matter of just scanning the code and changing providers in your phone’s settings.
Other times you can enter an activation code manually and if you’re traveling abroad, there are apps you can download which allow you to pick the country you’re going to and can then Auto provision an esim once you pay for it. But there’s currently a big downside to using built-in Sims and we’ll tell you what it is right after we thank today’s sponsor pulseway, the ultimate and one of a kind.

You know that thing we said a minute ago about carriers that support esim. Well, not every carrier does. Although many major carriers have started bringing in e-sim support, your options will often be limited when traveling abroad, at least for now. So if you want to shop for a better price or more data, as you often can, when visiting the shop at your destination airport, you may end up being out of luck, not to mention that e-sims tend to be more expensive than physical SIM cards.
But regardless of the current headaches for some Travelers, the future does seem to be heading towards phones without traditional Sim trays and there’s even a new style of internal Sim, we’ll see in the near future called isim where the I stands for integrated. In contrast to the i in iPhone, which stands for important instead of a separate chip, soldered onto the motherboard isim is actually part of the phone’s SOC or system on chip. The package, where core components like the CPU, GPU and modem live an isim is not only much smaller than an esim we’re talking less than one square millimeter wow, but it can also save on battery life. Two advantages that are extremely appealing to both phone manufacturers and consumers.
At the time we wrote this video there aren’t yet any phones that use an isim, but Qualcomm is already offering it as an option with their Snapdragon 8 Gen. 2 chips. It has the same advantages as esim, but also like esim. It requires carriers to get on board, we’re confident that more of them will over the next few years, but we just hope that it won’t continue to limit options for you, the poor consumer.
I guess it beats that sinking feeling you get when you’re about to fly home from vacation, and you realize you dropped your original SIM card in a foreign toilet and thanks for dropping in for the whole video wow. Thank you. .
