Do you update iOS?
 

Do you guys keep your iOS up to date with the new ICCID or you’re not the ones who like to take a risk?

Unlocked with rsim iOS 11.3 beta 4 it works but need to update via OTA not iTunes

You can do "UPDATE" or "RESTORE" via iTunes as long as the ICCID it's working. When the ICCID get blocked again then only "UPDATE" option.

You can ALWAYS do a safe update through wifi because there will be no re-activation screen. Never with iTunes.

I've been using srim 11+ until ios 11.2.5 because I have always updated with wifi update instead itunes. Now that I've done a DFU restore trouth iTunes I had to use a rsim 12 with the last iccid to make it activate again.
