IoT devices have different requirements than cell phones. But here too, SIM cards for IoT are at the heart of every network. Like the cards we insert into our smartphones, they connect to a mobile network via an encrypted connection.
What is the difference?
In certain areas and environments or for the conditions found there, the use of IoT SIM cards with their special performance features as well as their durability and robustness is highly recommended or even without alternative.
Even the standard version of IoT SIM cards differs from conventional SIM cards (for smartphones and tablets), e.g. in the resistance to various environmental influences and the guaranteed period of use / service life.
So-called “Industrial” IoT SIM cards are used for particularly difficult or extreme requirements and circumstances. This standard integrates and covers additional features that allow these SIM cards to be used for a wider range of applications and to withstand higher loads.
These “Industrial” IoT SIM cards are therefore only available in the individual formats / sizes 2FF (Mini), 3FF (Micro) and 4FF (Nano) or as a SIM chip – no “Triple SIMs” available. This ensures the best possible functionality of the SIMs.
Overview of performance features & characteristics of the various SIM card versions for IoT
Regular M2M cards
- Temperature resistance: -25°C to +85°C
- Guaranteed service life: 8 to 10 years
“Industrial” M2M cards
- Temperature resistance: -35°C to +105°C
- Guaranteed service life: over 10 years
- only available in individual formats, no combination sizes
- Slightly “thicker” than regular M2M SIM cards
