Which signal is better, Hefei Telecom or China Unicom?

Unicom's signal is quite good. China Unicom has always attached great importance to network construction, continuously invested money to increase the scale of network construction every year, and specially set up an optimization team to improve network quality. At present, Unicom's network has basically covered all provinces and cities in China. You can search and use Unicom signals locally or contact local manual customer service for help, depending on the actual situation of the local network.
