Using a cheapo SIM card/carrier in your homecountry (that perfectly works there) can be a problem abroad as they have no roaming partner. Means no SMS/OTP ecc arriving.

My US phone number is on a google voice account so I get calls and texts anywhere I have wifi or SIM card service.

Look into Tossable Digits service. You can keep your U.S. number - port-in / port-out as needed

It’s not about being able to keep one’s US phone number, it’s about getting 2FA from banks and other places that require it.

Fighting with ACLeada with this. I can do online credit card payments only with the code, sent by SMS. Nice, if you are in Indonesia, where Metfone has no roaming partner. I asked them to change to email, which they did (I get now account information as email), but the 2FA is still stuck on SMS. Argh!

Will keeping the main number on the virtual SIM and just using a removable local SIM for access work?

can someone explain how a dual sim works? I thought you have to transfer between sim cards for each one to work correct? If i am expecting an authorization from my home sim-- how would putting a local sim card help that?

I thought the advantage of having a dual sim means you don't need a seperate phone for the country you are in abroad. BUT how does having a dual sim allow you to receive messages from your home country thru regular text?

IS below correct?
If your phone is a dual-SIM model, or one that takes an eSIM, you can leave cellular on and data roaming off for your regular phone number and have data streamed to your other SIM.

This is the optimal combination for overseas travel. The data stream via your second SIM keeps all your apps functioning while the cellular connection to your primary number allows you to receive calls and messages. Or just buy a second-hand phone and put your regular SIM card in that, they’re cheap as chips.

At least the way more recent iPhones work, best I can understand.

Main number can exist as a virtual SIM or in the SIM slot. Other SIM is used for phone connection or internet. Calls or messages all go through the main SIM number.

Someone who knows more than me please feel free to better explain.

I am looking that up now. I am trying to figure out the nuts and bolts of it. Like what do you have to do to your phone in order to do that? I think you can only choose 1 sim at a time to be "working". Are you saying that you click my "home" number as the number "working" .. and the local sim would automatically be picked up because i am in the local area?

I am not sure, what you guys try to achive. If you have a eSiM, it is exactly the same, like you have a physical SIM. So having a eSIM + a physical SIM, is exactly the same thing, like having 2 physical SIM.

If a call gets in in either of the SIM, you can answer the call.
If you make a call, you can select, which SIM is used to make the call (there are some phones where you can preset, which numbers are supposed to use which SIM).
Both SIM are active (5 years ago only one SIM was active, but all phones are capable of that now).

To go back to 2FA - if you don't get the SMS on a single SIM setup, eSIM or dual SIM or whatever doesn't solve the issue at all
