3G cellular modules for Verizon and AT&T will be sunset completely in 2022. However leading up to the official sunset some areas will experience decreased coverage due to carriers reallocating resources. We recommend replacing the module sooner than 2022, or as soon as you experience signaling issues.
4G LTE cell sleds require the panel to be at firmware 3.1.3 or higher in order to be compatible.
Firmware is updated via USB drive locally (FW file saved in the root directory of a USB drive with no partitions)
We offer the 2GIG 4G LTE Verizon cell sled via our storefront.
