my iphone 5s couldnt be activated it say activation server is temporarily unavailable;e

Did you already try the troubleshooting mentioned in this article?

If you can't activate your iPhone - Apple Support

If the link provided by Ingo2711 above does not solve the problem, consider the following:

4 possible causes for that error message:

1] Activation server is actually down. Very rare occurrence, and of short duration when it

does happen. Solution - try again.

2] Your firewall and/or antivirus software are preventing the necessary connection. Solution -

temporarily disable your firewall and/or antivirus software until the activation completes.

3] computer being used for activation has been used to jailbreak an iOS device in the past.

Solution - use a different computer.

4] iPhone has been jailbroken. Your favorite search engine may provide some direction, but jailbreaks often prevent

activations/updates from succeeding. Per Terms of Use for this forum, discussion of jailbroken iPhones is

prohibited.
