Iphone WIFI "call home" function? -


we're deploying wifi hotspot service in locations via unifi. have sign mobile number , sms includes activation link.

the problem is:

the iphone seems check connectivity of wlan internet. so, after sent number, , before clicked on actvation link, theres no internet connection (basically is, youre not allowed outside of internal network until activation link has been clicked).

the iphone recognizes , disables wifi, because can't contact "testserver" - on 3g again, , activation link isn't reachable anymore.

my question:

does know ip iphone tries connect before deactivates wifi?

so whitelist ip reachable without authentication, iphone wouldnt disable wifi anymore.

i've tried catch via wireshark, didnt see anything. :(
