Among the 4G packages launched by Fujian Telecom, one of them is “Flow Card + Huawei B315s-936”.
The SIM card of this package cannot be used by the B315s-936 router. The device itself does not lock the card, the card also has a signal, and the connection is successful, but the Internet cannot be accessed.

Through testing, it is found that the SIM card binding device IMEI serial number, leaving the serial number can not access the Internet. The symptom is that the signal is normal, the network connection is normal, and it is inexplicable to open any network connection.
Because the B315s-936 has no battery for power supply, it is not convenient to go out and use it. Therefore, consider unpacking the binding and surfing the Internet with a portable device with a battery. Take the Huawei E5573s-853 supporting Telecom 4G as an example. The general process ideas and steps are as follows:
1. E5573S-853 downgrades the firmware. By command, the serial number is changed to the same serial number of B315S-936, and then upgraded back
. When the SIM is taken out and put into the E5573S-853, it can be connected to the Internet.
3. Because the two devices have the same serial number, in principle, do not use the Internet at the same time. If you are not ready to use the B315S-936 to access the Internet, you can use the serial number of the device. Change to E5573s-853, that is, the two devices exchange the serial number to avoid conflicts.
Note: The redirection is illegal and is for personal study and research purposes only.
