Network cards can be used in general areas now. Signal coverage is still possible. If you surf the Internet and chat on QQ, you won't get stuck. It can completely meet the demand. As for what kind of package is suitable, I am not a communication service provider, so I can't give you an answer casually. I suggest you go to the business hall to learn more about the related package business and tell the service staff about your situation so that they can recommend it for you. I hope it will help you and be adopted. Thank you.
