no, it is not possible. You have to ensure that your cells rxlev’s are stronger than the VPLMN’s cells. That’s a big game between operators at country border.. What you should do is inform the subscribers how to set their PLMN manually so their phone won’t camp on the other VPLMN.
That requires some ad campaigns or some mails, I guess.
