eSIM brings remote provisioning and future‑proofing, but most telematics hardware today still uses plastic SIMs. For most deployments today, physical IoT SIMs remain the practical choice in Ireland.
What an eSIM means in a tracker
An eSIM is a SIM built into the device as a chip. Instead of inserting a card, the network profile is loaded and changed remotely. A physical IoT SIM is a card (or soldered chip) that carries one fixed set of network credentials, and you swap it by hand if you need to change it. Both connect the device to a mobile network; the difference is how that connection is provisioned and changed.
eSIM Pros
- Remote provisioning
- Global profile options
- Less physical handling
Current Limitations
- Limited tracker compatibility
- Operational complexity managing profiles
- Mixed carrier feature support
Where each option fits
eSIM can make sense when the hardware you have chosen already contains an eSIM, when devices are sealed or hard to reach, or when units ship between countries and you want to change profile without a site visit.
A physical IoT SIM is usually the better fit when the tracker, gate controller, alarm panel or router has a SIM tray and no eSIM. Fitting or replacing a SIM is quick for an installer, and a multi‑network IoT SIM can already register on other supported networks where the home network is weak, which covers the resilience many fleets want from eSIM.
Questions to ask before you choose
- Does the device you are buying actually contain an eSIM, or only a SIM tray?
- Who manages the eSIM profiles, and what happens if you need to change network?
- Which networks and features (voice, private APN, fixed IP) are supported on the profile?
- What does a site visit to swap a SIM cost you, compared with the added complexity of remote profile management?
- Who do you call when a device drops offline?
If you are unsure which suits your devices, tell us the tracker or router model and where it will be used and we will recommend a plan that fits.
