How do I bypass roaming status?

[AC Question]

I want to bypass the roaming status and use the internet packages here in my country. There's an R symbol above the signal bar. I think I can only use roaming internet packages which I don't want. My phone is from USA. Is there a way? Root? Something?

Mobile networks.... Data roaming...
If you want to turn off international roaming you need to contact your service provider...
