How can I get local broadband if my out-of-town phone number cannot be used?

admin

Has been living away, my mobile number has been used for many years
But this broadband can only be used with a local mobile number
Mobile packages are enough to get broadband, but it's not worth using in the countryside where I live and rent accommodation
If you want to use it in the hometown's broadband, but can't
There is a monthly roaming fee of several tens of yuan which is not worth it
MJJ has other ways? Without changing my mobile number.
