Please follow the below steps:
1. Check whether a third-party security software is controlling the network speed.
2. Check whether a VPN is connected. If one is connected, we recommend you close the VPN.
3. If possible, replace the SIM card with another SIM card to confirm that the original card is not damaged.
4. Test the SIM card in other phones and compare the internet connection.
4.1. If the SIM card is normal but other mobile phones are also experiencing slow internet access, it may be that the regional network is abnormal or the data package has exceeded the daily limit and has been limited by the operator.
4.2. If the SIM card is normal, and other mobile phones can access the internet normally, you can try to clear the application cache or uninstall and reinstall the third-party application.
If the issue persists, contact the Nothing Support Team for further assistance.
