Series 02 – An Extended Version of Embedded SIM [eSims]


TGIF my readers and welcome back! I assume that our previous blog helped you understand what eSIMs are and its characteristics.

So what is within this blog then? You may find that soon, hold on. This time I didn’t purchase anything new, though. 

P.S my apple watch is doing wonders, guess what? I crossed 7,018 steps using the accelerometer synced with my health app. Is it an achievement?

NOTE: Your eSIMs can be installed only once. After successful installation, do NOT DELETE/REMOVE your eSIM from your smartphone.

So, are you travelling?

In principle, eSIM should mean that you can go to another country and simply add to your phone a roaming eSIM while retaining access to your primary “local” number. This is deemed to be one of the drawbacks at the moment, since, for example, if you change SIMs abroad, you can’t retrieve your own number. 

On the brighter side, it eliminates potential roaming chances abroad. This allows individuals to shift towards better operators in an area where signals could be an issue. This way an individual can quickly free up space to extend the battery life of the device or to add new features. This way they could reduce identity theft risks as well.

Wide adoption of eSIMs would be inevitable when customers and operators begin to see the advantages.

eSim – the sacred lost love of your device? 

One of the benefits that phone manufacturers provide is that we can get smaller devices so there is no need to fit a SIM card or the tray that carries it. Networks also do not need to generate or sell loads of SIM cards.

For other computers, such as laptops and tablets, eSIMs will also be outstanding, where flawless connectivity will become the standard. 

It is said that eSIMs would allow more smart devices simply because eSIMs do not need too much space within a system, enabling fitness trackers to perceive a stand-alone 4G or 5G connectivity in a way they were only unable to do before.

Practical elaborated eSim illustrative response: how will it actually work?

As good the question is, imagine you are provisioned with an eSim and physical (traditional) sim. You’re then asked to integrate both to two different network operators. Now your device, for instance, an iPhone will simultaneously display both networks on the device. Imagine you have added two physical sim cards resting conveniently in your slot, but in reality there is an embedded sim with a conventional one.

Customers would be able to answer calls and texts on both numbers if the handset is in standby and both the SIM and eSIM are supplied. You can then select a “default” line, to make calls, use along with iMessage (plus) FaceTime. The other line is for both SMS and voice only.

Tip: In the third series we will share hassle-free step-by-step installation methods. 

Conversely, you can only choose Use Secondary for cellular data – useful if you are overseas and use eSIM for local data. 

More than one eSIM can be installed on your iPhone, but you can only use one at a point. 

By tapping Settings > Cellular > Cellular Plans and tapping the plan you want to use, you can turn to eSIMs. It’s Mobile Data if you’re in the UK. Tap Turn ON, then on this line.

NOTE: We will cover installation in detail in series 03, this Wednesday. Keep an eye!

P.S There’d be a BONUS!

To be continued, folks. We’re reaching the final part soon.
