Dual-SIM and eSIM on Apple’s 2018 iPhones: Everything you need to know

Have you been thinking of the possibility of having two SIMs on your iPhone? Well, Apple has fulfilled that wish. When the company announced its iPhone XS, XS Max, and the XR series, it came with some great news that iPhone lovers were expecting.

Now, instead of splashing the cash on two iPhones to use separate SIMs, you can use two different lines on the same phone. That’s what the eSIM, a massive tech advancement Apple has built in its iPhone franchise, has solved. In this post, you will figure out everything you need to know about this eSIM technology.

What’s unique about the dual-SIM?

Instead of having two lines on two separate iPhones, the dual-SIM option makes it possible to use two lines in one phone. Another thing unique about this development is that it’s the first of its kind for Apple’s iPhone franchise, though Android devices like the Nuu Mobile X5 and Google Pixel 2 is already using this technology.

However, the dual-SIM (eSIM) is an alternative to the popular nano-SIMs. It’s a non-removable chip specially built into the iPhone device. And, once activated, it functions the same way the plastic SIM does. It’s also good news for travellers because they can make use of their iPhones abroad.

The thing is international data and roaming charges are on the high side. But with this eSIM, users can reduce call and data charges by adding a local phone plan when they visit countries where the infrastructure that supports this technology exists.

Is it possible to receive calls and text messages with the eSIM?

The eSIM is not different from the plastic SIM. But according to a paper editing service provider, it has more flexibility than the plastic SIM. What this means is that, users can switch from one network to another with ease. The process is as simple as turning on a Wi-Fi connection.

The dual-SIM can also make and receive calls and text messages like regular plastic SIMs. Another impressive thing is that it can take calls on both lines simultaneously. But when one of the lines is busy, calls entering the other will be stored as voice note.

The thing is the dual-SIM is an excellent idea for every iPhone user. You can even dedicate one of the dual-SIMs for business and the other for personal use.

In this case, both plans can only be from the same carrier. And again, if a CDMA carrier provides your first SIM, then your second

SIM won’t support CDMA.

At the moment, only the iPhone XS, XS Max, and the XR support the eSIM technology, and on iOS 12.1.
