Top 5 Mistakes Irish Companies Make Choosing SIMs for Tracking
The SIM is a small part of a tracking budget, but it decides whether a vehicle or asset reports reliably. These are the five mistakes we see most often, and what to do instead.
Mistake 1 – Using Consumer SIMs
They’re cheap upfront, but blocked and unreliable long term.
Consumer plans are priced and governed for phone use, and their terms can restrict use in machine‑to‑machine devices. Check the terms before putting one in a tracker, and choose a SIM designed for unattended devices.
Mistake 2 – Ignoring Multi‑Network Coverage
One carrier isn’t enough outside Dublin or Cork.
A single‑network SIM can only use that operator’s coverage. A multi‑network IoT SIM can register on other supported networks where the home network is weak, which matters for vehicles that leave the motorways and cities.
Mistake 3 – Overpaying for Data
Fleets don’t need 20GB bundles. Telematics uses kilobytes.
Check how much data your tracker actually sends each month and pick a plan, or a pooled allowance across the fleet, that matches it rather than a large bundle you will never use.
Mistake 4 – No Fixed IP/APN Support
Secure access is impossible without proper IoT SIM features.
A private APN or fixed IP gives your telematics platform a controlled route to the devices and lets you limit who can reach them. If your platform or security policy needs that, confirm the SIM supports it before you buy.
Mistake 5 – Choosing Providers Without Local Support
Fleets need fast Irish‑based support, not overseas call centres.
When a tracker goes offline, the quickest fix is someone who can check the SIM’s status and network registration straight away. Ask what support hours and contact routes you get, and who you will speak to.
A quick checklist
- Is the SIM designed for IoT and unattended devices?
- Is it multi‑network, so it can use other supported networks where coverage is weak?
- Does the data plan match what the device really uses?
- Are private APN or fixed IP options available if you need them?
- Is there local support you can reach when a device drops offline?
