eSIM?? You have one but just don’t know it


What Is an eSIM Card?

eSIMs are intended to replace traditional physical SIM cards. An eSIM is a tiny chip integrated in your smartphone rather than a detachable plastic card inside your phone.  Further, unlike a traditional SIM card, an eSIM cannot be taken out and inserted into another phone.The data on an eSIM can, however, be rewritten. This means that you may switch networks without having to remove your SIM card and enter a new one. The day when eSIMs totally replace physical SIM cards is, however, likely still a long way off. Currently, eSIMs are more typically utilized as the second SIM in a dual-SIM device.


What are the advantages of an eSIM?

With an eSIM, switching mobile networks is much easier. You may change networks by phone or online rather than obtaining a new SIM card, waiting for it to arrive, and then inserting it into your phone. You won’t even need a SIM ‘ejector tool’ to remove the old SIM from your phone. You can temporarily connect to another network. One eSIM may hold up to five virtual SIM cards at once. This means you can rapidly switch between networks if you find yourself in a place where your typical network has no reception. It also makes switching to a local network when travelling easier, as it eliminates the need to physically insert a local SIM.
Using a local cell network while travelling might be substantially less expensive than paying roaming charges to your Canadian network. Leaving your SIM card in your phone minimizes the likelihood of it being lost. It also allows you to use several SIM cards. eSIMs provide the same advantages as dual-SIM phones with two slots for traditional plastic SIM cards, the most notable of which is the ability to use two phone numbers on the same device. If you want one phone number for personal use and another for business but don’t want to carry two phones, this is a good option. You will always be able to receive phone calls and texts on both numbers, and you will be able to choose which SIM to use for making calls, sending text messages, and using data.

Another advantage of eSIMs is that they will eventually eliminate the need for a physical SIM card and tray. Smartphone manufacturers may then use this region to increase the capacity of a phone’s battery or to add new features to a device. Fewer holes in a phone also implies more protection from moisture and dust, which leads to fewer faults. In some cases, it may even be feasible to make handsets smaller. Wearables, such as smartwatches, offer a considerable space advantage since users do not want to carry a bulky device on their wrist.
The Apple Watch Series 5 and Series 4 models, as well as the Samsung Gear S2 and Gear S3 smartwatches, support eSIM.

What are the disadvantages of an eSIM?

If your phone breaks, chances are the little plastic SIM card stowed away within your phone will be unharmed. You may easily pull it out and install it into a new handset, but not with an eSIM. You will need to retrieve and download your eSIM profile from the cloud, which will take much more time. It also takes longer than transferring into a new handset when upgrading.

Users can be more easily tracked by network providers

Users concerned about privacy may simply prevent their cell network from tracking their whereabouts by removing the physical SIM card from their phone. However, because eSIMs are hardwired into the device and cannot be removed, eSIM users’ phones will be continually active on their carrier’s network and more easily traceable. While this should not be an issue for most people in nations like Australia, it might be a major issue elsewhere in the globe, such as for individuals belonging to organizations that are persecuted by their governments.


In terms of security, eSIMs are normally quite safe in that they cannot be physically removed and inserted in other devices by criminals, and they may be designed to require verification from operators anytime a user profile is changed. They are not, however, fully immune to fraud, with hackers sometimes going to tremendous measures to breach weak mobile carrier networks in order to collect user profiles or information.

Do all smartphones have an eSIM?

At the moment only a handful of the most recent smartphones and wearables have an eSIM. These include:

All of Apple’s latest iPhones – the iPhone XS, iPhone XS Max and iPhone XR, plus the new iPhone 12 range, and the iPad ProSamsung’s Galaxy S20, S21 and S22 phones
The Google Pixel 3 and 3 XL
Motorola’s Razr (only an eSIM, it doesn’t have a physical SIM card)
Samsung Gear S2 and Gear S3 smartwatches
Apple Watch Series 3, 4 and 5


Do all networks support eSIM?

It’s important to note that for eSIM technology to work, carriers need to enable the technology. Below are the Canadian carriers that support eSIM technology:
