This has been an issue with Apple phones for quite some time now because iOS no longer supports the option to edit the MMSC URL in APN Settings.

If your carrier is an iPhone Support Carrier, your settings will be updated automatically OTA (over the air) when you insert an active SIM card.

If you need to update Mobile Data settings to get 4G, you can always connect to WiFi and install a ".mobileconfig" profile (like this one): http://boss-cellular.com/BossCellular.mobileconfig

Profiles are no longer allowed to update your MMSC APN settings.
