What does data pooling mean?

Data pooling means that a common data quota is used for the M2M SIM cards used.

Data pooling: A pool for active M2M SIMs.

Data pooling refers to a data quota used jointly by all active M2M SIM cards of a customer. Instead of defining a separate data volume for each M2M SIM card, all active SIMs are combined in a large pool and the end devices consume the data from a shared quota. If one device consumes more data than others, the lower consumption can compensate for the additional consumption. This procedure makes particular sense when M2M SIM cards with different and fluctuating data requirements are used in an M2M tariff. The data from the pool are then offset against each other, so that it is rather rare for the pool to be exceeded due to individual M2M SIMs.

At wherever SIM we distinguish between a dynamic and a static data pool. With the static data pool, the data quota for all SIM cards remains the same, even if new M2M SIM cards are activated. So if 50 SIM cards are already active and have a data pool of 100 MB, the data pool remains at 100 MB even when five more SIM cards are activated. With the dynamic data pool, on the other hand, the data quota grows: if another M2M SIM is activated in addition to the 50 SIM cards, the 100 MB data pool for all SIM cards increases by a size specified by the customer, in this example 2 MB per M2M SIM. In total, the 55 M2M SIM cards have 110 MB available in the data pool.

Alternative data limit: Prevent excess consumption by setting limits.

An alternative to using the data pool can be to set up a data limit. This defines the maximum amount of data that the M2M SIM may consume. If the limit is reached, no more data can be transmitted. Whether setting a data limit makes sense or not depends on the intended use. There are devices that can do without data transmission. However, there are also cases in which data must continue to be transmitted in any case, for example in telemedicine.
