It is a hit or miss whether the GPP chip you’re using will still work as the update may contain a fix that will prevent you to continue using your local SIM card. Updating your GPP unlocked iPhone into its latest version comes with a wide variety of new features and also, problems. Yes, you could, but there are obvious caveats. So, should you update your GPP unlocked iPhone? The answer is a mixed bag.

GPP unlocked iPhones are way cheaper than factory unlocked iPhones as a majority of these are region or carrier locked or even refurbished, possibly stolen surplus iPhones coming from China, Korea, and Japan.Īpple routinely releases a new version of its operating system, better known as iOS, whenever it introduces new phones. However, this SIM tool usually has limitations such as no LTE support and firmware compatibility, meaning if iOS updates to the latest version, the tool might not work.
GPP is a SIM spoofing tool that is inserted into a carrier locked phone along with your local SIM in order to bypass the carrier restrictions and can be used on local networks.
