Mexican temporary numbers on InstantSMS use the +52 country code. Mexican mobiles are typically ten digits nationally; in full international form they look like +525512345678. Always copy the E.164 value from the number card - dropping the country code or truncating digits is a frequent OTP failure. Mexican lines are useful when a service expects a North American Spanish-speaking region number, or when you want a disposable inbox instead of sharing a personal celular.
