A. 1. Restart your device: Sometimes, a simple restart can help re-establish the connection. Turn off your device, wait for a few seconds, and then turn it back on. 2. Check APN settings: Go to your device's settings, find 'Mobile Networks' or 'Cellular Networks', and then 'Access Point Names'. Ensure that the APN settings for Movistar are correctly configured. If you don't have the correct settings, you can usually find them on the Movistar website or by searching for 'Movistar APN settings'. 3. Toggle Airplane mode: Enable Airplane mode for a few seconds and then disable it. This can refresh your network connection. 4. Contact your service provider: If the issue persists, check with Movistar to ensure that your recharge was successful and that there are no outages in your area.
