PRL list & Roaming | Telit Cinterion IoT Developer Community

We are using the PVS8 cdma cell modem on one of our devices. We are experiencing some roaming issues where our devices sends data while connected to a roaming tower, but we don't recieve any data. After updating the PRL list we experience more losses in some areas.

There is a AT command, AT^SCFG, that allows the modem to select which frequencies to choose from in the PRL list. Under the <AutoAB> parameter we can select either:

“autoa“           Acquire the available system only from System A.

“autob“(D)      Acquire the available system only from System B.

“any“               Acquire any available system according to PRL.

I can't find any info on what any of these options actually mean.

Can you please provide any more info for what selecting one of these systems means for the PVS8?
