有wifi吗？

You just walk up to someone and say the phrase. It is grammatically perfect and very short. If you want to be more polite, add 请问 (qǐngwèn) at the start. That means 'Excuse me, may I ask.' Most people will understand you even if your tones are a bit off. Just point at your phone and look hopeful.

Use it the moment you sit down at a cafe. Use it when you check into a hotel. It is perfect for restaurants with QR code menus. You can even ask a friend when visiting their home. Basically, use it anywhere your data plan starts to sweat. It is a great icebreaker in a new environment.

Do not use it in a very formal business presentation. It might make you look distracted by your phone. Avoid asking a random stranger on a busy street. They likely won't let you tether to their personal hotspot. Also, do not use it in places where silence is expected, like a temple. Your soul needs a connection, but maybe not a digital one.

China is a mobile-first society. Almost everything is paid for via apps like Alipay or WeChat. Because of this, asking for Wi-Fi is not just about browsing. It is about being able to function in daily life. Most public places expect this question and have signs ready. In the early 2010s, this phrase became a symbol of the 'smartphone generation.'

You might hear 密码是多少? (mìmǎ shì duōshǎo?). This means 'What is the password?' People often say these two phrases back-to-back. Another variation is 这里有无线吗? (zhèlǐ yǒu wúxiàn ma?). 无线 (wúxiàn) is the more formal word for 'wireless.' However, wifi remains the king of convenience. Everyone from kids to grandmas knows what it means.
