my rm502q-ae connects to lte and nsa 5g just fine, but refuses to connect to NR5G.
I insert my Sim into my iPhone 12 and am able to access NR5G
In the US most carriers are using NSA mode that’s why it’s important for US customers to get an NSA type modem (RM5xxQ-AE work well). Basically it idles the modem on LTE channels then kicks it into 5G mode whenever there’s large data transfer taking place (and only during then). You cannot force SA mode only when the carrier doesn’t support it.
