💡 Setup Tips

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

• Make sure Mobile Data and MMS are enabled.

• Add dun to the APN Type if you’re using hotspot/tethering.

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

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