Some iPhone X buyers in US unable to activate devices

San Francisco, Nov 4: In a first major glitch in Apples "super premium" iPhone X, buyers in the US took to Twitter to report issues related to activating their new devices.

"The issue seems to be affecting some AT&T, Verizon and Sprint users in the last few hours when they tried to get service on Apple's $1,000 phone. When users tried to activate the device, a message popped up saying, 'The activation server is temporarily unavailable', The Verge reported on late on Friday.

A buyer tweeted: "Hey @Apple not sure if you heard, but the #iPhoneX came out today. Maybe fix the activation server? Now, please."

"Well I got my iPhone X. Activation appears to be another issue entirely. Continuous 'could not activate iPhone' message," tweeted another user.

Apple is yet to comment.

However, the issue could just be related to iPhones purchased directly from Apple and not from the carriers in the US.

"Some of our customers experienced a delay activating their iPhone X," an AT&T spokesperson was quoted as saying.

Apple introduced its much-awaited iPhone X globally, including in India, on Friday amid heavy demand.
