Android Mobile Data Not Working? Test With Wi-Fi Off

Keep Wi-Fi off and try a browser and another app. If only one app fails, focus on that app’s settings and service. If both fail, toggle Airplane mode on, wait 10 seconds and turn it off. Wait for the phone to reconnect before testing again.

On Pixel, go to Settings > Network & Internet > SIMs. Make sure Mobile data is on and the intended line has Use SIM enabled. On Galaxy, go to Settings > Connections > SIM manager and check the Mobile data selection. Menu names vary by model. After a SIM change, check whether the new line is active with the carrier.

With Wi-Fi off, look for a mobile data label such as LTE near the signal bars. If it is missing, move outdoors or test somewhere you usually have coverage. If the label is present and several apps fail, check the data usage limit in Settings and the remaining allowance with your carrier. While travelling, confirm the selected line and its roaming rates before enabling Data roaming.

If the issue persists, ask your carrier to check coverage, outages and data activation on the selected line. If they point you to the APN, use the settings they provide. On Galaxy, Access Point Names is usually under Settings > Connections > Mobile networks. Record any custom settings before restoring defaults.

Open a fresh page with Wi-Fi still off. If it works in another location or on a different SIM, tell the carrier where it fails and which line you tested. If the carrier confirms the line works and the problem follows the phone, ask the phone maker about mobile network troubleshooting for your model.
