How to Update Your APN (Access Point Name) on Android

The APN (Access Point Name) tells your phone how to connect to mobile data and MMS. If you’ve installed a new SIM or eSIM and data isn’t working, you may need to set it up manually. Follow this step-by-step guide.

Before You Start

• Turn Wi-Fi OFF (forces the phone to validate mobile data).
• Make sure Mobile data is ON.
• If you have Dual SIM or eSIM, choose the correct line first.
• Keep your APN value handy (this can be found in your dashboard).

Universal Steps (Most Android Phones)

1. Go to Settings.
2. Tap Network & Internet (or Connections / Mobile Network on Samsung).
3. Tap Mobile network → Access Point Names.
4. Tap Add (➕) or ⋮ menu > New APN.
5. Enter the APN details from your provider.
6. Tap Save and then select the new APN.
7. Toggle Airplane mode ON then OFF – or restart your phone.

Troubleshooting

• Save button greyed out? Ensure APN field is not empty and has no spaces.
• New APN won’t stick? Make sure you’ve selected it after saving.
• Access Point Names missing? Check correct SIM/eSIM is active. Some carrier devices lock this menu.

FAQs

• Do I need to enter every APN field?

  No. Only fill in the fields provided by SimplySIM (only NAME and APN). Leave others blank or at default.

• Will this affect my calls or texts?

  No. APN settings only control mobile data and MMS. Your calls and SMS will still work normally.

• What if I can’t see the APN option?

  Some eSIM profiles or carrier-locked devices disable manual APN editing. If this happens, contact SimplySIM support for advice.

• Do I need to restart my phone?

  Yes. Restarting or toggling Airplane mode refreshes the connection and applies the new APN.
