3G coverage in rural areas of Weifang, Shandong Province. Unicom Telecom Mobile. Which signal is good? Low tariff

I suggest you buy a mobile one. There must be a mobile signal. The biggest advantage is that the tariff is low, and the equipment is only more than 400 but less than 500 a year. The time limit for telecommunications is 90 hours per month, and the equipment is at least 800 a year. Unicom is even more expensive. Of course, the phone is always disconnected, which is very painful to say.
