Pro Tips / Dealer Notes

  • Always double-check the APN settings—they’re a common culprit after SIM swaps or carrier changes.

  • If data works in another phone, the issue is likely device-related (settings, software, or hardware).

  • Some prepaid plans may restrict data after a certain usage—verify plan status before advanced troubleshooting.
