Version Comparison

Differences

The main differences between SIM7028 and SIM7020G are frequency band support and data transfer rates. The SIM7028 supports more frequency bands and slightly higher data rates, making it suitable for more markets and applications with higher bandwidth requirements. Although SIM7020G has slightly less frequency band support, it also covers most of the market and is suitable for general iot applications. The two are similar in network protocols and functional features, as well as extensive international and carrier certifications.
