Excuse me, which one has a better signal, foreign mobile phone cards or portable Wi-Fi ?

I use a SIM card, it's convenient and cost-effective.
The phone card works better, and there is signal even at Shao Nv Peak.
The signals are the same. The portable WiFi can be used by five people and has a longer range. The mobile hotspot can be used by three people and has a shorter range.
