Why is iqoou35g slow

You can check the troubleshooting methods for slow data network:

1. Is there a metal protective shell or a magnetic support? If there is, I suggest you take it off and check it.

2. Confirm whether the SIM card phone bill is sufficient: if it expires, it can be recharged, restart the phone or switch flight modes;

Whether the traffic reaches the operator's limit: When the total traffic usage reaches a certain value, the operator may limit the network speed or access the Internet. Please consult the operator's customer service for details.

Whether to use the Internet of Things card: Internet of Things cards are generally used for smart devices, and the network speed may be limited;

Comparison test of replacing SIM card: Please put other SIM cards into the mobile phone to determine whether the SIM card itself is faulty. If the SIM is damaged, it is recommended to go to the operator's business hall to replenish the card;

3. It is recommended to enter Settings-Mobile Network/Dual Card and Mobile Network-Mobile/Unicom/Telecom-Access Point (APN) and reset to the default settings;

4. Compared with different signal coverage areas, the coverage of mobile phone signals is easily affected by the environment, such as underground parking lots, elevators and other environments, and the signal will be relatively weak. Please try to go to an open place, such as an outdoor open environment, to see if the data network speed is restored;

5. Please go to Settings-System Management-Backup and Reset, select "Reset Network Settings" and try again.

Note: Resetting the network settings will reset the WLAN, mobile data network and Bluetooth connection records.

6. If the above methods are ineffective after operation, you can take the mobile phone and purchase certificate to the customer service center for testing and processing in time.

It is recommended to call in advance before going to avoid empty running, plan your trip reasonably and travel safely.
