By comparison, which one is more useful, WiFi or phone card ?

I am using AT&T mobile card, it is good. I only went to the city, not to the wilderness.
Feeling that wife is better in most cases.
SkyLink of Huawei is very useful. The main purpose of buying a phone card is to make emergency calls. If you don't buy a card, you can also use IP phone, but you must have traffic.
It's all the same.
I was also afraid at the time, so I bought both.
