Trying to activate my new iPhone 5

if you are trying to activate using WiFi I suggest restarting the device and try activating it using your cellular data. If unsuccessful you’ll need to connect to a computer that has the lastest version of iTunes installed to try activating it that way. Below I’ve attached a helpful link. Good luck.

Its a new phone

That's impossible. It's been discontinued for years.

If you're having a problem activating it and you want help, you need to tell us what's wrong. We have no idea what's happening when you try to activate it.

I bought it from the mobile phone shop which sells new products.

Then you got ripped off.

It was discontinued in September of 2013. 2013!

It can't run anything higher than iOS 10. It's already 2 generations behind and soon will begin having problems finding apps that run on it.

Return it and go buy a current iPhone from an authorized retailer or directly from Apple.

A used device you bought?

Take it back to where you bought it.

An iPhone 5 is seven years old.

Just because it’s discontinued doesn’t mean it’s impossible. Some third party carriers still sell iPhone 5’s. Furthermore some of the later model iPhones experience this same activation error.

You bought a used device that wasn't properly set up for resale.

The last owner is the only person that can activate it.

An iPhone 5 sold anywhere in the world is a used device.

Take it back and beg for your money back.
