Are those ATT Unite Mobile Hotspots made by Netgear Wireless AC770S Unlock-able?
I'm trying to unlock my ATT Unite Hotspot AC770S paid retail price, but ATT unlock website doesn't recognize the IMEI number! Chat with ATT Customer Service and I'm informed that those ATT Unite units can not be unlocked. Can anyone verify this info as few people here were able to unlock them legitimately by ATT? Thanks.
