The eSIM will replace conventional SIM cards

 

The latest Apple Watch, Samsung’s G2 smartwatch and any number of tablets and Windows notebooks already have them: the eSIM. Swisscom is one of the first suppliers in the world to support the integrated SIM. Read on to find out the eSIM’s capabilities and advantages.

 

 

It’s only the size of a fingernail and yet, these days, nothing works on your mobile without it: the SIM card. “SIM” stands for “Subscriber Identity Module” and it is a chip card that enables users to access their carrier, such as Swisscom. In actual terms, Swisscom uploads the customer’s profile, such as subscription information, telephone number, etc. to the SIM card. This card is then inserted into the mobile as a mini, micro or nano SIM card. Up to now.

 

The “embedded” SIM

 

The conventional SIM card will soon be a thing of the past. Technology now makes it possible to upload the customer profile to the SIM retrospectively, removing the need for an external SIM card. Instead, the SIM is integrated directly into the device as an “eSIM”, where “e” stands for “embedded”. The network operator uploads the profile direct to the eSIM, eliminating the need for physical SIM cards to be swapped over when customers change providers. Ordering, modifying or replacing a SIM card, and the fear of damaging it, will soon be relegated to the past.

 

Even the tiniest of devices can communicate

 

The new eSIM enables small devices, such as smart watches, glasses or activity trackers, to operate in the network, making these devices independent and allowing them to communicate without a smartphone. The Apple Watch Series 3, for instance, is already doing this now. It has many of the same functions as the iPhone, such as making phone calls or receive messages. In fact, it can do anything that the small display allows. This makes it very useful when playing sport, for instance, as you can leave your smartphone at home and can still be contacted.

 

 

An eSIM for smartphones will come on-stream later

 

Smartphone SIM cards are not set to be replaced imminently. For the time being the iPhone XS, XS Max and XR will not support eSIM in Switzerland. So for now, the heart of your phone will still be a conventional SIM.

 

 

 

eSIM as a key to the Internet of Things

 

Millions of machines and everyday objects are already fitted with sensors and radio chips. In the future, this number will reach into the billions. These devices can communicate with each other and with the Internet: carparks report the number of spaces occupied and letter boxes send a message once a parcel arrives. The eSIM ensures that these objects are always connected through the mobile network. It is the key to the Internet of Things.

Good article, very clear on the big changes ahead.

 

Still, this paragraph would need some clarification:

 

An eSIM for smartphones will come on-stream later

 

Smartphone SIM cards are not set to be replaced imminently. For the time being the iPhone XS, XS Max and XR will not support eSIM in Switzerland. So for now, the heart of your phone will still be a conventional SIM.

 

Is there a timeframe for this feature to become available?

 

I see a great use for this feature, allowing the main contract with Swisscom to be on the eSIM, and the external would be used for a second provider when travelling abroad, without the need to swap SIM cards (and thus losing the capability of receiving calls) or worse having two phones (which is what I am doing currently).

 

I am keen to order the iPhone XS, but I would love to be able to make the most of the device, especially since it’s much larger than my current iPhone SE+iPhone 5S combo.

 

Many thanks, Luca

Hello Luca

 

There are only a few providers worldwide where the eSIM and Dual SIM functionality is activated. There is no provider in Switzerland. Swisscom is technically ready to use eSIM. We see eSIM as a positive development for the mobile communications market. Unfortunately, we don't know when Apple will implement eSIM-Technology for Switzerland.

Thanks Miriam,

 

Hopefully this will be implemented sometimes in the near future also for Swisscom mobile customers.

 

Many thanks,

By the way, for what concerns Apple’s eSIM support and the different mobile providers in the world, this page shows which providers currently support eSIM on the new iPhone Xs/Xs Max, and clearly Swisscom is not listed there yet, unfortunately:

Another very useful page, which describes in great details how the dual SIM operations work on iPhone’s iOS is this:
