Maps, taxis, translation, tickets and payments all assume you are online. This is the one thing worth settling before you fly — everything else in Shenzhen is easier once it works.
For a layover or a short stay, the ranking is almost always: travel eSIM first, roaming as backup, local SIM only if you need a Chinese phone number.
| Option | Rough cost | Good for | Watch out for |
|---|---|---|---|
| Travel eSIM | From ~US$4 for 1 GB / 7 days to ~US$30 for 20 GB / 30 days | Short stays; anyone who wants data the second the plane lands | Data-only, so no Chinese phone number — which some apps (and some hotel bookings) want. Buy and install before departure, then enable data roaming on that line after landing. |
| Tourist SIM at the airport | ≈ ¥80–300 for 10–30 days with data | Longer stays; anyone who needs a +86 number for Didi, Meituan or hotel check-in | Passport plus on-the-spot identity verification (usually a photo), and 15–30 minutes of queueing. Opening hours vary by operator — some counters close around 21:00. |
| City carrier store | ≈ ¥50–80 for 30 GB | Best value if you have an hour to spare in the city | Little English. Show your passport, point at the tourist plan, use a translation app. |
| Home carrier roaming | Varies wildly — check before you fly | Emergencies, and for receiving bank SMS codes | Keep your home SIM active for verification texts even if you use an eSIM for data. Roaming is often the most expensive route by a wide margin. |
| Wi-Fi only | Free | Waiting at the terminal | Public Wi-Fi in malls and cafés usually requires a Chinese phone number to authenticate. Don't plan a day around it. |
Travel eSIM for data + your home SIM left switched on for SMS. The eSIM gives you maps and payments the moment you land; the home line keeps receiving the one-time codes your bank sends when you bind a card or make a large payment. Pulling your home SIM out and leaving it in a drawer is the single most common self-inflicted problem — you discover it at the exact moment you need a verification code.
All of these are bought online, installed by QR code, and route outside the Great Firewall. Prices below are common entry / size points — check the live plan for your dates. None of this is an endorsement; pick on price, data and how long you stay.

Alternatives worth a look: HelloRoam, MobiMatter, Ezy eSIM, Maya Mobile, KnowRoaming. For a stay longer than a week, or if you must receive Chinese SMS, a travel eSIM alone won't give you a +86 number — see the other options below.
Google, WhatsApp, Instagram, Facebook and most Western news sites aren't reachable from a standard mainland Chinese connection. Two practical consequences: many international travel eSIMs route traffic through Hong Kong or Singapore, so those services work on cellular data with no extra setup; and if you install apps at home, they'll be ready when the connection permits.
Install a maps app that works in China before you fly — Apple Maps, Amap (高德) or Baidu Maps — and download the offline map for Shenzhen. Same for your translation app's Chinese offline pack. These two are the difference between stranded and fine, and they are the ones people forget because at home they already work.
Do this on home wi-fi. Several of these are awkward or impossible to download once your connection is routed through mainland China.
| App | Why you want it |
|---|---|
| Alipay | Payments plus the metro/bus ride code. Highest priority. |
| Messaging (everyone here uses it), payments, and how hotels and guides will contact you. | |
| Didi | Ride-hailing with an English interface and automatic payment — no hailing, no negotiation, no pronunciation problem. |
| Amap (高德) / Baidu Maps / Apple Maps | Navigation that actually works with local road and transit data. Amap has some English support; Apple Maps is the friendliest foreign option. |
| Trip.com / Ctrip | Trains, attraction tickets, hotels, and English-language customer service that answers the phone. |
| Dianping (大众点评) / Meituan | Restaurant discovery, reviews and booking. Chinese-only but worth having if you have a local number. |
| A translation app | Camera mode is the killer feature — point it at a menu, a sign or a medicine packet. Download the Chinese offline pack. |
| Your airline's app | Boarding passes, rebooking, and lounge eligibility — especially important if you're on a tight connection. |
Most "my eSIM doesn't work" problems are one of four settings after landing. The full walkthrough has the exact menu paths for iPhone and each Android brand, plus the fixes.
Check compatibility, install before departure, then the four settings to change on landing — and what to try when data won't connect.
Open guide →Once you're online, the next job is paying. The full walkthrough lives on the payment page — open it for the real-name verification screens, WeChat's hidden "Services" menu and card-refused fixes.
Open guide →Why these two are separate pages: getting online and being able to pay are different jobs, but you need both and they interact — you cannot bind a payment card without a working connection, and a data-only eSIM still leaves you unable to pay. Sort the connection first, then set up payment.
