EC21-E (QuecOpen version) China version

Hi everybody,

I would like to know if module EC21-E with QuecOpen support could work in China or there is a specific version. I didn’t find anything in EC21 comparison table on quectel website


Hi @davdav
From Quectel_EC21_Series_LTE_Standard_Specification_V2.0.pdf,you can use China Telecom and China Unicom (B1 B3).
