FAQ
- What should be done if a metal phone case causes poor cellular signal?
Remove the metal protective case or magnetic holder to eliminate signal interference. Move to open outdoor spaces for better signal coverage if weak‑signal areas such as elevators or underground parking lots cannot be avoided.
- How to verify whether apps are permitted to use mobile network?
Open iManager and navigate to Data monitor > Network management to confirm app internet permissions. Note that certain device models do not carry this function, so skip this check for unsupported devices.
- What effects will resetting phone network settings bring?
Resetting network settings reverts Wi‑Fi, mobile network and Bluetooth configurations to factory defaults. It will not erase personal files, but previously saved Wi‑Fi passwords and paired Bluetooth devices need re‑configuration.
- What checks are required when the SIM card causes no‑internet issues?
Confirm the SIM card is not out‑of‑service due to arrears or data‑usage cap. Recharge, reboot the phone, consult the carrier or replace a valid SIM card when relevant anomalies are detected.
