Why does my phone keep switching networks near the falls?

Puerto Iguazú sits at the tri-border, so phones often try to roam onto Brazilian or Paraguayan signals. Lock your network to an Argentine operator (Personal, Claro or Movistar) to stay on your eSIM and avoid dropping the plan.

Does the same plan cover the Brazilian side of the falls?

No. It's an Argentina-only national plan, so the Brazilian side and Foz do Iguaçu aren't included. You'd need a separate Brazil eSIM for that visit, even though it's just across the bridge.

Good to know in Misiones

Near the tri-border, your phone may try to roam onto Brazilian or Paraguayan networks and leave Argentina's plan; lock your network to an Argentine operator (Personal, Claro or Movistar) to stay on your eSIM.

Best time to visit Misiones

The falls impress year-round, but March to May and August to October bring milder, less humid weather than the intense heat of high summer.
