Hi Peplink Team,
Currently eSIM is not supported for FusionSim. And with Peplink devices limited to 2 eSIM per modem we see this as a solution for multi area applications to work with more eSIMs per modem.
As more Mobile Network Operators and Mobile Virtual Network Operators are (slowly) changing over to eSIMs it keeps FusionSim an added value to the Peplink ecosystem.
Is there a possiblity to add this feature?
Thanks in advance.
I think thereās merit to this request - Iād appreciate having this feature! But the FusionSIM platform is āfreeā for us, I guess cost is included in SIM adaptors sold. If we all migrate to eSIM, this platform should be paid for how?
Alsoā¦ latency continues to be a big factor for both FusionSIM and eSIM from our testings unfortunately. Globally weāve found. Thoughts on that being an issue going forward?
FusionSIM will be a payed subscription, as Peplink is planning a public release of the service soon. Currently it is still in beta.
There will be an option to pay a fee per active link or per active FusionSIM platform.
The eSIM will still need some platform to host the SIM card itself, but maybe it can be added to existing Injectors?
Also, how are you experiencing issues with eSIM and latency? When you change the profile? The eSIM profiles should be stored on the local device when it is installed, the same way a physical SIM would work.
We have used eSIM only once across Europe, but are heavily using FusionSIM inside The Netherlands, so latency is manageable within the country.
Weāve seen increased latency using FusionSIM outside of country of SIM origin.
Same for eSIM, but we did see different performance depending on breakout location which is something weāre investigating.
This is all testing done in AU & NZ - in Europe we have not seen these issues.
When a SIM card roams, it always goes back to the originating country. FusionSIM or eSIM canāt fix that. So you should experience the same āextraā latency when using physical SIMs if it roams to a further away country.
We havenāt used FusionSIM outside NL, but have used eSIM across several countries in Europe and didnāt notice a difference in performance and latency on the physical SIM or eSIM from the same provider in NL.
We have roaming prepaid SIMs that roam via Spain for instance, when we use those in the Netherlands they have an added latency of about 75-100ms. Depending on eSIM provider they also offer different packages for different originating countries to mitigate the extra latency.
my 2ct.
When we started developing FusionSIM solution, the idea was to assign local SIM cards from a single remote location. In other words, device is one located, while all SIM cards are stored in remote location. With the current implementation the router will drop a FusionSIM and will ask for a new FusionSIM every time when the router changes the cellular network. So if need to roam between two carriers, the router will drop the FusionSIM and ask a new FusionSIM. The new FusionSIM will be provided based on configuration settings. For example you can configure to allocate local SIM cards first based on GPS data, so that when you travel across Europe, it is possible to have a local SIM card which provided remotely in each country. The data/traffic latency is not related to FusionSIM. FusionSIM is only about communication between remotely stored SIM and the cellular modem. If there are issues with traffic/data latency then this is due to carrier, SIM card plan or other reasons, but not the FusionSIM technology.
Since FusionSIM is not uploaded to device like eSIM it is very easy to change SIMs between devices. That is not the case with eSIM. Both eSIM and FusionSIM has cons and pros and it always up to the application.
As I understood from Joey initial post, the idea was to store eSIMs in single remote location and then use FusionSIM technology to provide SIMs to routers. Since FusionSIM doesnāt store physical or eSIM on the device it would allow changing eSIMs between devices easily. Joey will correct if I am wrong 
Thanks for sharing Giedrius!
Yes I completely agree with you on the eSIM vs FusionSim part.
If FusionSim supports eSIMās it would indeed make it much easier to swap between eSIMās in multi region projects or when you have different plans with different usage rates.
