How can i change IMEI of Huawei E5770

Hello everyone

Is there any way to change IMEI of Huawei wifi E5770 ?

Because the telecommunications company in my country has a 1800 and 2300 frequency for 4g but the frequency 1800 is banned in routers and works only in mobile phones and to lift the ban on frequency 1800 routers must change IMEI

So is there a way to change it ?
