how to get the IMEI of IPhone or IPad device?

In general, iOS does not let you get at persistent unique identifiers (the IMEI, the UDID, the Wi-Fi MAC address, and so on). [The only exception is on managed devices, where MDM has access to this sort of thing.] In non-enterprise environments, you have to use various different identifiers depending on the context. To learn more about this, watch:

• WWDC 2012 Session 710 Privacy Support in iOS and OS X

• WWDC 2013 Session 714 Protecting Your Users’ Privacy

Hello eskimo,

thank you for your reply,

now i have a question, i want to develop an app, the app only install in corporate devices, not allow in personal devices. in general i think of to use IMEI to identify which device, but now i don't get IMEI, how to handle the case, hope you give me some advices based on experiences, i know the question is over the scopt of your function, but still hope get a little bit information thank you very much again

Best regards,

Navy

To be clear, an app can’t get at the IMEI even in a corporate environment. Rather, your MDM server can request the IMEI from the device, at which point you can write code—on the client, possibly with a server-side component—to correlate that with your app.

Hello Quinn, I do have an enterprise account, but link seems not finding anything about MDM 😟

OR is this? "depsim User Guide"

thanks in advance.

Indeed. I’m not seeing anything either, even after switching to the Enterprise team that DTS uses for testing this sort of thing, which is weird because I used to be able to see it.

OR is this? "depsim User Guide"

No.

You should get in touch with DTS formally and our MDM specialist should be able to point you in the right direction.

Hello eskimo,

Is it Possible to Collect IMSI number with MDM? If so Any available Docs for it? I searched and i couldn't Find Any. Note IMSI is different from IMEI..
