Transport layer security should mean this shouldn’t matter. A good POS shouldn’t rely on a secure network, the security should already be built in cyptographically at the network session layer. Anything else would still have the same risk vector, just a lower chance of happening.

In fact many POS systems happily just take a 4g/5g sim card because it doesn’t matter what network they’re on.
