Uh, SMS
reception from your home carrier should not be a problem, regardless of who your home carrier is.
The system works like this: When you are roaming on someone else's network with your (home) SIM card, the network you are roaming on sends a message in the background to your home carrier, saying
"Hey, this customer of yours is roaming on our network." Then, if someone sends a SMS message to your home network, your home network checks to see if you are on the home network (meaning, if you have returned home since it got that notification from the foreign network), and if you are not on the home network, your SMS gets forwarded to the last network that notified your home network that you were roaming on it.
As for being able to
SEND a SMS from your home network account when you are roaming on a different network, that's a different set of protocols, and I don't know the rules for how that works.
But if all you need to do is
RECEIVE a SMS from your bank, or airline, or website, or whatever to tell you what your two-factor code is to authorize a login, you should not have problems.
Of course, all this is contingent on your phone being able to connect to the foreign network frequencies (see my post about this above). But you should be able to see if you have connected pretty easily by looking at your phone.
