GROUP Data Plans – SIMs on a group plan effectively share data with other SIMs on the same plan, for example if you have 5 x 10MB SIM cards you have a “pool” of 50MB of data shared between your fleet. This way if you have devices that under-utilize their data allowance, devices that go over their allowance can borrow from the pool. NOTE: Once your devices have exceeded their “pool” allowance you will be charged excess usage per KB.
