Is the Rizhao Unicom signal good? (I went to college in Rizhao this year) Thank you.

After the merger of China Netcom and China Unicom, the new Unicom has invested a lot of money to triple the number of base stations, and the network coverage has been quite good, especially in cities, which is equivalent to mobile, and some cities have surpassed mobile. However, the original Unicom gave a poor impression, and it will take 1 or 2 years to change.
