Is there a way to disable roaming on the TransPort WR21?

Digi TransPort WR (Series)

I have an issue where I need to disable the roaming of one of my modems/SIM cards. Is that possible to do with the TransPort WR21?

No, at least not that Digi can directly support. This is controlled by either the roaming list on the SIM (if GSM or LTE) or in the PRL (stored on CDMA modems).

n some cases you can lock to a specific carrier (MCC/MNC) but this is not recommended.

Hi,
and thanks for answering.

I have had to disable it on the SIM card, but I find it odd that it is difficult to support as this functionality is present in all phones I have seen.

The solution I have now works, but is a bit inflexible.
