The 49/89 package cancels the national roaming, and the package will include the call duration and Internet traffic. Beyond this range, making a phone call or surfing the internet will cost extra diplomatic fees.
On the other hand, if you don't have to do it, you still have to pay a monthly package fee of 49/89.
As for whether to charge only this package fee, I suggest you go to the business hall or call 10000 to see if the supporting services for your mobile phone are included in the package of 10 yuan.
