Frequently Asked

SIM vs. eSIM:

The core feature of the eSIM that sets it apart from traditional SIM cards is the ability to change and host multiple network operators.

Can I replace all my current SIMs with eSIM right now?

You could, eSIMs are perfect for specific cases that need the ability to remotely manage the network operator profile such as for connected cars that may be resold in different regions, or thousands of water meters that, without remote provisioning, a technician would have to swap SIMs manually. Eventually, eSIM and remote provisioning will be the standard for IoT/M2M deployments.

How is eSIM and IoT/M2M connected?

eSIM is already changing the game for IoT/M2M rapidly in two main areas. The first is the ability to harness local data rates no matter where your devices end up. The second area is the ability to manage the operator profiles for devices that are in hard to access areas or devices that are environmentally sealed. For these devices, the ability to remotely swap the network operator profile is paramount since it is often impossible or costly to physically access the SIM card itself.

Is eSIM still really necessary for M2M?

We think it is! As the M2M industry grows and more and more devices are connected, there will be an exponential amount of SIM cards built into nearly every kind of device you can think of. Now imagine having to physically remove a SIM from those devices to manage the connectivity provider changes. Well, with eSIM that becomes a thing of the past, and as M2M grows, then it becomes a critical requirement to manage device connectivity.

How is Consumer eSIM different than IoT or M2M

The main difference is that the consumer is a Pull model where the end user will have the ability to manage their profiles on a need basis, whereas M2M is based on a push model where the Device owner would push the changes to the operator profiles to the devices.

Soft SIM vs. eSIM

There are some similarities between the Soft-SIM that Apple has been developing for years with Gemalto and an eSIM. While the purpose is similar between the two (Over The Air provisioning), Soft-SIM doesn't include a physical SIM at all, and the provisioning info is stored in the memory of the device. However, in their current state, this makes Soft-SIMs more exposed to hacking and malfunction. As the eSIM solution is based on a GSMA standard and it's the only globally-oriented remote SIM specification, it's the best solution for now.

How do we manage our eSIM Operator Profiles?

1oT's Terminal is fully integrated with Remote Provisioning platform(s), the Terminal will offer you a full eSIM subscription management functionalities along with the billing, changing status and location info.

What Form Factor does 1oT offer?

1oT offers multi-profile eSIM in 2FF (mini), 3FF (micro), 4FF (nano) and MFF2 form factors.

How disruptive will eSIM be?

Service providers have enjoyed relative stability in traditional SIM models for quite some time. Now, however, if they don't change their models, they may find themselves in for a shock. The idea of how the revenue flow should work will inevitably need to change since now the SIM card is not locked to an operator or service provider. Ultimately this will be the most significant game-changer, service providers will need to convince through superior service and quality that you should not simply swap to another provider. To do this the internal way of thinking of how to conduct business and retain customers must change and ultimately only those service providers who adapt to these changes will be successful with eSIM.

Does my old 1oT SIM get eSIM capabilities?

Unfortunately no. eSIM cards look the same but have different software running on them.

Can I swap between carrier profiles if the SIM is unable to get a connection on the enabled profile?

Yes, the whole eSIM idea resolves around swapping the profile with the carrier which fits best your needs, in terms of Coverage, network quality and let's not forget pricing.

Can I bring over eSIM management to 1oT with already existing eSIMs?

Yes, GSMA has mandated the interoperability very strictly, which ensures any eSIM management platform may manage eSIMs from any manufacturer. Please contact our eSIM experts to discuss the idea and concept.

Is NarrowBand IoT a CAT-M1 supported via eSIM?

Yes, as you would have understood by now we can download and enable profiles on an eSIM, this profile can be an NB IoT supported. As 1oT will have the control to make changes to the eSIM, we can easily enable NB-IOT and CAT-M1 functionalities.

Does 1oT support Voice calls and SMS on eSIM as well?

Yes, but this would be on a case to case basis.
