There is a slightly weird tweak I figured out to do this. For any incoming SMS, you can get its originating SMSC's GT (Global Title) which generally tells you which network the SIM is on. So we can send a silent SMS to any SIM and check its network on the reply.
I haven't tested the whole loop, only the first part. Tried sending silent SMS for the second part, but somehow unable to do it properly. However, on paper, the logic seems OK. I guess commercially it might be expensive than direct lookup because HLR lookup cost is cheaper than SMS sending.
