Now Di Wei Township, Guangnan County, Wenshan Prefecture, Yunnan Province can't use China Unicom, and there is no signal directly.

First, the cell phone signal is poor because the signal will be affected by various factors such as topography, landforms and tall buildings. If your location is relatively closed, the signal will be affected. You can restart your mobile phone, or change your mobile phone card to that of your family and friends and try again to see if the signals of other Unicom users around you are normal. If your signal problem has not been solved, please contact customer service 100 10 for consultation and reflection.

2. If your mobile phone can't surf the Internet normally, please check the following: 1. If you don't restart your phone after upgrading to the 4G package, you can't use the Internet function normally; 2. Confirm whether there is a network. I suggest you use it in a place with strong signal. 3. Check whether there is any phone bill in the account. If the balance is insufficient, it needs to be recharged before it can be used; 4, can be turned off for 3-5 minutes, restart the phone and try again; 5. Check whether the USIM card is inserted. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not. 6. If the traffic reaches the peak in that month, the network will automatically shut down. We suggest you pay attention to our SMS reminder or inquire about the package product description.
