Multiple carriers per SIM

I have a customer asking about what I think is carrier switching with the same SIM in your products (BR1 Mini’s, etc.).

Resending request:

I have a customer, Globalgig, asking about what I think is carrier switching with the same SIM in your products (BR1 Mini’s, etc.).

Here is the customers request for feature here:
5) MOST URGENT ITEM: Logic on cycling MCCMNC, PLMN Codes on our multi-carrier SIMs. We need to demonstrate how to cycle the carriers, and we also need to be able to speak to and demonstrate the logic as to why the router switches between available carriers:

France EEA Orange FRAF1 20801
France EEA Societe Francaise du Radiotelephone S.A. FRAF2 20810
France EEA Bouygues Telecom FRAF3 20820

I’m not seeing a way to do this yet in the web interface of a Mini or on the User Forum.

Please let me know if this is possible. If it’s not currently, then please consider this a feature request.
