If you have a phone that supports eSim and physical sim (dual sim) and you are using a US financial institution - then you could assign the eSim to a US cell carrier that supports international service, ie T-Mobile, or a mobile virtual network operator (MVNO) like U.S. Mobile. See if they have a cheap international cell/text only plan.

You may want to call the financial institution and see if they support SMS over VOIP (ie. Google Voice). I believe I read that Wells Fargo does not.

Or if your financial institution can use other methods; call, email.

@Eeyan
the problem is, if the provider does not have a local roaming partner or simply doesn't work for whatever reason, you don't get the SMS. This problem are facing a lot of people in Cambodia or especially in Indonesia. A local SIM is nice to have internet, but it won't get you any SMS that is sent to the SIM/number, which is not working.
@BklynBoy You can't get the SMS/text through any other SIM, than it is sent to. If you have working roaming for the SIM in question, no issue, you get it. If you can't get network for whatever reason with it, you are f***ed.
For data: you can select on your phone, which SIM is supposed to use the data and here for sure the local SIM should be used (because of the costs)
Driving on Cambodian roads is just like playing a classic arcade top scroller. The only difference is a force feedback controller, the limitation to only one life and the inability to restart, once Game Over

You should be okay getting SMS overseas while using Wi-Fi with your US carrier. Usually you will have a problem when it’s over 90 days, usually they will freeze your service until you return to the U.S.

Just a recommendation, DO NOT turn roaming on, you will get killed on roaming charges.

Who is your cell phone carrier?

I use MetroPCS . I spoke w/ someone at MetroPcs and they added something called "Global Voice metro by Tmobile) 10 dollars extra per month They also said I can turn data roaming on. ( since I know within an hour or so of when i should be getting this text- I can turn roaming on and then shut off)

Last summer i did get text messages on my phone when i was using Wi-Fi but it was spotty. That was possibly because my apartment wifi wasn't the best. I was thinking in worst case I can go to Starbucks and use their wifi When i need the banking codes. I have someone in NYC that can initiate the process BUT they send a code to my NYC number and i cannot change it

It's a little confusing to me how a local sim would help this situation. The local sim gives me data correct? and that can help get texts from NYC? again you can ignore this part if sounds crazy.

I used verizon international plan when overseas a few times, it sucked in Cambodia. I think Metfone is their partner, the internet was terrible. I used Smart E-sim but had to switch on the Verizon a few times to get texts, each day I used it was $10 per day so that is not budget friendly.

I am with T-Mobile. They assured me because I had been with them for so long that they would not freeze my account. After 16 months I am still able to get SMS from my bank. However, I do make sure that I don’t use it for anything else, Wi-Fi calling, text messages to family and friends, because I know their assurance means nothing.

If you are with any one of the major carriers you shouldn’t have any issues, regardless of spotty internet service, it has more to do with you being with MetroPCS.

I don't get, what @Kenr means by "You should be okay getting SMS overseas while using Wi-Fi with your US carrier" or "DO NOT turn roaming on, you will get killed on roaming charges"

The first one is simply wrong, you can not get an SMS by WiFi. SMS is part of the GSM protocol. If the SIM is off (flight mode, deactivated or no roaming), there is no way to get a SMS

The second one is not fully correct as well. You can have turned roaming on and even having the worst contract in the world, getting an SMS is always free (because you can't prevent it to get). To prevent charges, don't make a call, don't answer (!) a call, don't send SMS and don't switch on data on the SIM that is roaming

That’s funny because I don’t use roaming or cellular data on the phone with my US sim and I get SMS from my bank and text messages when I do turn on that phone using Wi-Fi.

The second one is correct, I’ve been burned on it before several years ago while in Thailand.

Bottom line is, depending on your US carrier, you don’t need to turn on roaming or cellular data to receive messages.
