When comparing prices, you must look beyond the sticker cost and evaluate the channel capacity (e.g., 8, 16, 32, or 64 ports). A higher port count increases the price but lowers the cost-per-channel. Ensure the device supports 4G LTE or 5G bands relevant to your region, as older 2G/3G hardware is cheaper but being phased out globally. Additionally, check for IMEI rotation capabilities and BCCH modification features, which are critical for preventing SIM blocking and ensuring operational longevity.
