Hi, so here's the situation : I need to access government services in a different country to the one I live in permanently, and therefore I need a number in said country with the ability to receive SMS for login and payment confirmations. How should I go about it ?

I guess the easiest thing to do would be to wait for the next time I go there and buy a cheap SIM card there. But the problem is I'm only going to that country in a year from now, so I'd like to speed up things.

I thought about getting an e-SIM with the lowest amount possible of data, but it still comes out pretty expensive for just receiving confirmation messages.

Anyone have a better idea on how to do this ? How do double citizens go about this usually ?

Edit : didn't think it would matter much, but the country I need a verification number in are Brazil and Colombia, while I am in the EU
