If an iPhone or an iPad (Wi-Fi + Cellular) is sharing a Personal Hotspot, you can use its cellular internet connection. Go to Settings > Wi-Fi, then choose the name of the device sharing the Personal Hotspot.

The iPad does not require a SIM card to work. The SIM card just lets it connect to a cellular service provider’s network for internet access but is not required. You can do anything that requires an internet connection over Wi-Fi

The default login username and password both are “admin”. If you or someone had changed them but you forget them now, the only way to access the modem/router is to reset the router to factory default settings. Note: If you reset the device, the device will return to factory defaults, and you will lose all your settings.
