How to Get Online in China, Cuba, or Iran Where Your Normal Apps Just Don't Work

Your Google Maps, your WhatsApp, your Instagram — half of them go dark the moment you land in a censored country. Here's how to access the internet in China and other walled-off places, set up the right way before you go.

Figuring out how to access the internet in China as a traveler — or in Cuba, or Iran, or anywhere with a serious firewall — is a different problem from normal travel connectivity. It’s not about signal or data caps. It’s about the fact that the apps you live on at home are simply blocked, and the tools to get around the block often can’t be downloaded once you’re inside the wall. So the whole game is what you do before you fly.

I found this out the hard way in Shanghai, standing in a hotel lobby, trying and failing to download a VPN because the app store had quietly hidden every VPN in the country. Google Maps: dead. WhatsApp: dead. Instagram, Gmail, the lot: dead. I had a working SIM and full bars and I was completely cut off from everything I used. Rookie mistake. Don’t be me.

It varies wildly by country and it changes, so check close to your trip — but roughly:

China has the most thorough setup, the Great Firewall. Google (search, Maps, Gmail, Drive), Instagram, Facebook, WhatsApp, X, YouTube, most Western news — all blocked. China runs its own brilliant ecosystem (WeChat for everything, Baidu Maps, Amap) that mostly assumes a Chinese phone number, which tourists often don’t have.

Iran blocks a lot of social media and messaging, with periodic broader shutdowns; what works one week may not the next.

Cuba is less about hard censorship and more about scarcity — limited, slow, often pricey access, historically through state WiFi cards, though it’s loosened. Some apps are blocked, but the bigger issue is just getting a connection at all.

The point: assume your defaults won’t work and plan for it, rather than discovering it in a lobby.

Here’s the move that surprises people. If you use a travel eSIM whose data is routed back through its home network rather than the local one, your traffic often exits the censored country before any filtering kicks in. In plain terms: your phone is physically in China, but your internet “comes out” somewhere uncensored, so the firewall doesn’t apply the same way.

A lot of travellers report that international roaming data — from a regular foreign SIM, or a roaming-style travel eSIM — reaches Google, WhatsApp and the rest in China without a VPN, precisely because it’s not using the local filtered network. It’s not guaranteed and providers change their routing, but it’s one of the most reliable, least fiddly options, and it needs zero VPN gymnastics.

So: set up a reputable travel eSIM for the region before you go, test that it installs, and you may find your normal apps just… work.

The single biggest thing. Once you’re inside the wall, the app stores often hide the very tools you need, and the websites to download them are blocked too. So while you’re still home, on your normal connection, install:

• Your VPN app — and actually open it, log in, and pick a couple of servers so it’s ready. A reputable paid one; in heavily censored countries the free ones mostly don’t work and the good paid ones invest in staying ahead of the blocks. Have a backup VPN as well, because no single one works everywhere all the time.
• Offline maps. Download the whole city (and country, if you can) in Google Maps offline, and install Maps.me or Organic Maps which work fully offline. When live Maps is blocked, offline maps with GPS still pinpoint you perfectly — your phone’s GPS doesn’t need the internet.
• A translation app with offline language packs — Google Translate’s offline Mandarin or Farsi pack is a lifesaver when you can’t reach the live service.
• Any messaging app you’ll rely on, configured and logged in. In China specifically, consider setting up WeChat before you go (ideally with a friend already on it to help verify you), since locals use it for literally everything including payments.

If it’s not on your phone and working before wheels-up, assume you can’t add it once you land.

Some days, especially during local crackdowns or shutdowns, your VPN will crawl or die and the roaming trick will sputter. Plan as if that day will come, because occasionally it does.

Screenshot the essentials: your hotel address (in the local script too — show the taxi the characters), your booking confirmations, key phrases, the metro map. Download your itinerary so it lives on the phone, not in the cloud. Keep a little cash, because if your payment apps and connection both fail at once you don’t want to be stranded. And tell someone at home your rough plan, so a day of silence doesn’t trigger a panic — in some places a comms blackout isn’t an emergency, it’s a Tuesday.

China: roaming eSIM is the smoothest path; failing that, a tested paid VPN. Set up WeChat. Get a friend to help you verify the account. Offline maps mandatory.

Iran: lean heavily on a tested VPN and download everything in advance, and accept it’s volatile — what works shifts, so have two VPNs and offline maps ready, and don’t put anything sensitive through local networks.

Cuba: the problem is access and speed more than blocking — get connectivity sorted (eSIM coverage has improved), keep expectations low, and pre-download maps, translation, and entertainment for the long offline stretches.

The throughline is the same everywhere behind a wall: the internet you know won’t be there, and the tools to fix it can’t be fetched once you’re inside. Do the boring prep at home, carry two ways through, and have an offline plan for the day both fail. Get that right and you stay connected — or at least functional — where most travellers go dark.

Set it all up on your home WiFi before you fly, because the one place you can’t download a VPN is the place you’ll most need it — ask me how I know.
