Is calling Mexico free
Calling Mexico is not automatically free. It may be free if your mobile or landline plan includes Mexico calling, if both parties use an app over data, or if a company gives you a reachable local number.
WhatsApp and similar apps do not charge per minute for app-to-app calls, but your internet or roaming plan may charge for data. Business callers can use SIP Trunking with usage-based pricing for the lowest per-minute rates.
