EG25-G ppp issue

I am trying to use PPP with quectel EG25-G and raspberry pi and it is working, when I try to upload a file to FTP server from raspberry pi, it is uploading very slow, I am using jio sim which doesn’t have any fallback on 2g. Are there any settings or at commands in ec25 so that module will fix the network coverage to 4G itself and doesn’t have any fallback?

Dear Sir,
Thanks for your inquiry in Quectel forum.
Please note that the PPP speed is slow compare with network card dial up. And you test it in real neywork, the speed may be limited by many reasons. So in order to make sure the speed is enough to upload the file to FTP server, it is better to change the dial up method.
Please note that the module have no ability to solve the network coverage issue. Thanks!
