💡 Setup Tips

• Save and select the new APN, then restart your device.

• Make sure Mobile Data and MMS are enabled.

• Add dun to APN Type if your plan supports hotspot/tethering.

• On iPhones, the correct APN usually loads automatically once the SIM is inserted and carrier settings update.

• If MMS doesn’t send, confirm the MMSC and MMS Proxy match the values above.
