Q: FaceTime is not working on different country SIM

Please see the article below.

Wireless carrier support and features for iPhone in the Middle East - Apple Support

Especially this note.

FaceTime may be unavailable if your device originates from this region and becomes unlocked or is used in another country.

What is the model number of the iPhone. Look at Settings=>General=>About

=>Model. You may have to scroll to get to the entry for model.

If the iPhone was originally meant for the Middle Eastern markets where FaceTime

is prohibited, you will not be able to use FaceTime even if the iPhone is moved

to a country where FaceTime is allowed. While Bahrain may not prohibit FaceTime,

you could have been sold a gray market iPhone from a country where FaceTime is

prohibited. Provide the model number so someone may offer a solution.

That iPhone is meant for the Middle Eastern market. You will not be able to

install FaceTime on that iPhone. Sell it to someone who can use it in a

restricted country and purchase an iPhone from the country where you

intend to use it. Or keep that iPhone and use Skype or similar app in place

of FaceTime.

My friend has purchased iPhone 6 from Bahrain and he is coming to India next week.
Model number - A1586

Can you please say if Facetime will work once he comes to India ?!

If the phone was legally sold in Bahrain, as opposed to a gray market device that originated from another region, then no. It will be disabled.
