Unfortunately, no. eSIM (eUICC) cards look the same as regular SIM cards (UICC). Still, they have different software running on them that can not be updated.
If you are interested in switching to eSIMs, get in touch with us.
1oT offers eSIM in 2FF (mini), 3FF (micro), 4FF (nano) and MFF2 form factors. We can support you with commercial, industrial, and automotive grade eSIMs on all the mentioned form factors.
To swap carriers, your cellular module needs to support Bearer Independent Protocol (BIP) and SIM ToolKit (STK) for remote SIM provisioning.
We have covered the topic in more detail in this blog post. If you have more questions, feel free to write to us at support@1oT.com.
If your hardware does not support eSIM transactions, you can still use the SIM with 1oT's Default Carrier (bootstrap profile). It provides global coverage in 2G, 3G, and 4G in over 190 countries.
Sadly, you will be locked in that profile, and you can't enjoy the benefits of eSIM with many profiles.
To swap carriers, you need to log in to 1oT Terminal and access the eSIM Management Tool. There you'll find full eSIM subscription management features along with a comparison tool to find the most suitable Carrier. After finding a fitting Carrier, you can swap with a push of a button.
No, you cannot. In M2M eSIM, there needs to be a "middle-man" who aggregates a pool of different carriers. That's also a reason to choose an independent service provider like 1oT. We have integrated several carriers under one eSIM infrastructure and can offer flexibility to choose between them.
