PDP Authentication Failure usually means either the APN is wrong or the plan is out of data/validity.
- Ensure the APN is set exactly as shown in your activation email.
- Verify the plan still has data and days remaining. If it is empty, top up at ozlyesim.com/topup, then restart your device to reconnect.
- Select a supported network manually if automatic selection latched onto an unsupported carrier.
- Reset network settings (Settings > General > Reset > Reset Network Settings) and reboot.
