Can any one refer me to an English-speaking techie who can help me navigate the telephone/wi-fi world in Buenos Aires ? I have an iPhone 14 Plus which has also a digital SIM card. I downloaded an Airalo app which is supposed to be allowing me to make calls overseas using my digital SIM card. I also have different cellular data and travel numbers on my phone. And an account with Movistar, which doesn’t seem to provide any service. I don’t under any of this. I was able to make a call to New York City on Monday to an office that doesn’t use WhatsApp. But that won’t work today.
