STC – also known as “Metro” – partnered with AT&T to bring free Wi-Fi to Mexico City’s subway Line 3. This is (coincidentally?) the third line to get an open internet connection, after 7 and 1.
Connecting to it is as simple as looking for the “CDMX METRO WIFI” hotspot and proving an email account. After agreeing to the terms and conditions, you can start surfing at no cost during your ride.
STC’s Wi-Fi is actually pretty good. I opened Fast to measure the speed and got almost 2 Mbps, fine to browse the web, check Facebook, and send WhatsApp messages. The connection is reliable, unlike Wi-Fi spots on planes.
There is no mobile connection on Line 3, as it is underground. In the yesteryear, you had to save things for offline consumption and miss any new WhatsApp texts you received. Now you can stay online even if you ride Line 3.

The only downside, apart from you connecting to an open hotspot (I suggest you turn on a VPN to protect your privacy), is that you have to be on the lookout for pickpocketers.
Someone stole my iPhone 6 Plus on Line 3 two years ago, right when I was hoping off. I was so angry and promised myself not to take my phone out while on board.
As a tip, if you are a tourist and hop on Line 3 and decide to sit down and connect to the new free Wi-Fi connection, please be aware of your surroundings. Someone might be checking you out.
It’s a shame you can’t surf the web without any worries. Rides would be more entertaining. Picture yourself watching YouTube and checking your Facebook wall while commuting to your job.
You can always use a spare mobile phone while on Line 3, or use your time to read a book 😉
