Apple iOS APN Settings

Configuring APN Settings on Apple iOS

Important — Please Read Before Installing

Apple iOS devices are unique in that APN settings cannot be entered manually through the Settings screen. Instead, you must download and install a custom APN configuration profile.

It is vital that your mobile data plan is set to KeySIM at the point you install the profile. This is how Apple determines which SIM card to apply the profile to. Installing the profile while a different SIM is selected as the data SIM will result in the APN being applied to the wrong SIM card.

Installation Steps

1

Set your mobile data plan to KeySIM, then tap the download button above

First go to Settings → Mobile Data → Mobile Data Plan and select your KeySIM card. Then tap the Download APN Profile button above. A Profile Downloaded confirmation popup will appear — tap Close and open your Settings app.

2

Open Settings and tap Profile Downloaded

Open the Settings app. You will see a new Profile Downloaded banner near the top — tap it to proceed to the installation screen.

3

Tap the KeySIM APN profile under Downloaded Profile

You will be taken to the VPN & Device Management screen where you will see the KeySIM APN profile listed under Downloaded Profile. Tap it to open the installation screen.

4

Tap Install in the top-right corner

The Install Profile screen will show the KeySIM APN profile details. Tap Install in the top-right corner to proceed. You may be prompted to enter your device passcode to confirm.

5

Review the warning and tap Install to confirm

iOS will display a Warning screen noting the profile is unsigned and that network traffic may be filtered by a mobile data configuration. This is expected — the profile only sets the APN name to key and does not monitor or intercept your data. Tap Install in the top-right to complete the installation.

Profile installed! Your iPhone or iPad will now use the correct APN settings for your KeySIM card. If data does not connect immediately, toggle Airplane Mode off and on to force a reconnection.
