APN — Access Point Name — is the string a phone uses to reach iD Mobile for data, MMS and hotspot. Wrong values leave the SIM connected but unable to load pages.

Below are iD Mobile's recommended APN values for Android and iPhone — name, username, password, MMSC, MMS proxy and port. A 'connected but no internet' state points at the APN.

Entering iD Mobile APN values on iPhone

On Android 10 and up, iD Mobile's APN screen sits at Settings → Network & Internet (Connections on Samsung) → Mobile Network → Access Point Names. Plus icon adds a profile; tap an entry to edit.

Galaxy handsets: Settings → Connections → Mobile Networks → Access Point Names. Xiaomi and Redmi use Settings → SIM cards & Mobile Networks → Access Point Names.

Saving an APN does not activate it — you must select it
On Android, after tapping Save the new APN appears in the list but is not yet active. Tap the radio button (empty circle) next to it so it becomes filled. The profile is only active when the circle is filled. Then toggle aeroplane mode or restart.

iPhone iD Mobile mobile data not working after APN entry

On iOS 16 or later: Settings → Mobile Data → Mobile Data Network. If absent, iD Mobile likely pushes the APN automatically. A reset restores iD Mobile's defaults.

Newer iPhones on iD Mobile's carrier bundle may grey out the APN field — contact iD Mobile for a settings update.

APN field greyed out? Here is why
On Android: the field is locked by a carrier profile. Go to Settings → Network & Internet → Mobile Network → Access Point Names and tap Reset to Default (three-dot menu). On iPhone: the carrier bundle controls the APN — it cannot be edited manually. Contact your network to push an updated carrier profile, or insert the SIM in another phone to test.

APN values are case-sensitive — enter them exactly
Type every character exactly as shown — no spaces before or after, no capital letters unless listed. One wrong character stops mobile data from working. After saving on Android, tap the radio button (filled circle) next to the new profile to activate it.

Does iD Mobile automatically configure iPhone APN?

Type iD Mobile's values into the APN screen, leaving unlisted fields blank. Save, restart, then select the profile.

After saving your APN settings, always restart your phone and test a website before making further changes. If you have multiple APN profiles, make sure the correct one is selected (shown with a filled circle on Android).

Fastest way to apply new APN settings
After saving, turn aeroplane mode ON for 10 seconds, then turn it OFF. This forces an immediate network re-registration — quicker than a full restart and equally effective.

Troubleshooting iD Mobile APN issues (iPhone)

Still no data after entering iD Mobile's APN values? Work through these in order:

1. Toggle aeroplane mode — ten seconds on, then off — forcing a iD Mobile reconnect and APN re-registration.

2. Restart fully — this clears short-lived faults and applies the new iD Mobile values.

3. Rebuild the APN. Delete iD Mobile's entry and retype it — one wrong character breaks data.

4. Reset all network settings. Android: Settings → General Management → Reset → Reset Network Settings. iPhone: Settings → General → Reset → Reset Network Settings. iD Mobile's defaults return.

5. Check the iD Mobile account — SIM activation, standing and data allowance are all verifiable via the hub or customer services.

Common MMS mistakes that stop picture messages working
• The MMSC URL must begin with http:// — never https://
• The MMS Proxy field is an IP address only — no http:// prefix
• APN Type must contain mms (e.g. default,supl,mms)
• On Android, save then select the profile before testing

APN settings for MMS on iD Mobile (iPhone)

iD Mobile's MMS uses dedicated APN fields — MMSC, MMS proxy and MMS port. Check those first when picture messages fail.

Why is my iD Mobile APN greyed out?

iD Mobile locks the APN field on some devices and SIM types. Greyed out on Android? Look for reset APNs under Settings → Network & Internet → Mobile Network. On iPhone the carrier bundle controls it — ask iD Mobile for an update.
