I'm in a hurry to go to Vancouver, Canada tomorrow. I don't know if I should bring short sleeves. What season is twenty degrees equivalent to?

Supplement: the problem of mobile phone. Both Canada and the United States use tri-band mobile phones, that is, tri-band or quad-band mobile phones with the frequency band of 900/ 1800/ 1900MHz. Some domestic mobile phones are dual-band and can't be used, but now most 3G mobile phones are quad-band and can be used.

If the M-Zone needs to open international roaming service, go to the business hall. But it's expensive, five or six yuan a minute, and it costs more than one yuan to send a message.

If you use it for a long time, it is recommended to buy a local card. There are two kinds of local cards, one is SIM card and the other is CDMA. Many suppliers in Canada also have many packages, and the charges are different. Relatively speaking, mobile phone charges in Canada are relatively high.

If you want to buy a card, it must be approved by a Canadian supplier. Just ask when you buy a card.

Bring more short sleeves. There is no need for air conditioning here, just an electric fan. It only takes 1-2 days a year.

The most comfortable season in Vancouver is from March to 10. Much like Kunming.

It's ten degrees at night, and the temperature difference won't be great, but when you first arrive here, you should pay attention to the temperature difference between morning and evening, or you will catch a cold easily.

Moreover, ultraviolet rays will be stronger than those in China, so pay attention.
