The XP5 is a durable and reliable tool on a customers’ tool belt.”

“Quick and reliable communication is critical for field workers,” said Igor Glubochansky, executive director, AT&T Mobile & Business Solutions. “AT&T Enhanced Push-to-Talk on the Sonim XP5 helps keep them connected, whether they’re on a Wi-Fi network or the nation’s most reliable 4G LTE network.6 This lets them adapt to the needs of their environment and better serve customers.”
