Can I make emergency calls (like 911 or local equivalents) using my SouthESIM?

SouthESIM is a data-only service, meaning it provides internet access but doesn't support traditional voice calls or SMS. For emergency calls, you'll need to use your primary physical SIM card with its regular phone number, or find a local landline. Always keep your primary SIM active, even if you turn off its data roaming, so you can still make emergency calls if needed while exploring places like Colombia or Vietnam.
