Which one has better signal in Tibet, "Haoyitong" or mobile phone?

Personally, I think Haoyitong and China Mobile have the best effect, while China Unicom signal is relatively poor! The biggest advantage of Haoyitong is that it is cheap, but the signal is relatively poor compared with China Mobile. China Mobile is the best in Tibet, and the coverage is also the best. The network has basically covered the counties and towns along the Qinghai-Tibet Railway and in the region. , if you often travel on business, it is recommended to use mobile, and for fixed work in Lhasa, it is recommended to use Haoyitong, and Tibet's Haoyitong supports Tibetan text messages! If you choose mobile, it is best to apply for a package service!
