Remote monitoring and diagnostic services provided by gplink operate through either GSM service or through various satellite technologies. On a global scale, most countries have their own rules and regulations to follow for communications and radio frequency use. In order to sell in specific countries, gplink must first be reviewed and certified by that country’s communication commission or department. gplink said it has been working to be certified in dozens of countries throughout the world and announced that Peru is now online for gplink services, both GSM and satellite.
