How to Use DiDi With a Travel eSIM (Without Getting Stuck at the Curb)

I’ve missed one DiDi pickup because of a phone number problem, not a data problem. That distinction matters more than most guides let on, and it’s the reason I wrote this one.

DiDi isn’t just a China app anymore. It now runs rides in Mexico, Brazil (under the 99 brand), Colombia, Chile, Peru, Costa Rica, Panama, Ecuador, the Dominican Republic, Argentina, Australia, New Zealand, Japan, Egypt, and across much of Southeast Asia — Singapore, Vietnam, Malaysia, Thailand, the Philippines, and South Korea among them. If you’re heading to any of those, a working data connection from the moment you land is what makes DiDi actually usable. That’s where a travel eSIM comes in — and where a few small setup mistakes quietly derail people.

Why DiDi Needs an eSIM, Not Just Wi-Fi

DiDi has to see your live GPS position to match you with a nearby driver, track the car in real time, and confirm you’ve been dropped at the right spot. Airport Wi-Fi drops the moment you leave the terminal, and hotel Wi-Fi obviously doesn’t follow you to the street corner where you’re trying to flag a ride. Mobile data is the only connection type that stays with you.

You’ve got three ways to get it: pay your home carrier’s roaming rates (usually the most expensive per gigabyte), buy a physical local SIM (cheap, but it kills your home number until you swap it back), or install a travel eSIM before you fly. For a trip built around ride-hailing, food delivery, and maps, an eSIM tends to win on convenience alone — no SIM tray tool, no shop queue, and your regular number stays active for calls and app logins.

The Verification Problem Nobody Mentions

Here’s the part most “how to use DiDi abroad” articles skip entirely, and it’s the single most common reason a first-time DiDi setup fails.

When you register or log into DiDi for the first time on a new device, it sends a one-time SMS code to confirm your number. A pure data-only eSIM — the cheapest, most common kind sold for travel — has no phone number attached to it at all. It can move data, but it can’t receive a text message. If your only working line during the trip is a data-only eSIM, that verification code has nowhere to land.

Three ways around this, based on what’s actually worked for me and other travellers I’ve compared notes with:

• Register before you fly, using your home SIM’s number while you still have normal signal. Do this a day or two ahead, not at the gate.
• Keep your home SIM active for SMS only, and let the eSIM carry the data load. Most modern phones run two profiles side by side — this is the standard dual-SIM setup, and it solves the problem cleanly.
• Choose an eSIM plan that includes a local number, if one’s available for your destination. Data-only plans are usually cheaper, so weigh that against the hassle of losing SMS access.

If you’ve already left home and your DiDi account isn’t registered yet, option two is really your only path.

Setting Up DiDi and Your eSIM Before You Land

Do this the night before departure, while you still have reliable Wi-Fi to work with:

1. Install the eSIM profile first. Every travel eSIM provider sends a QR code or an activation link by email. BazTel skips the QR step entirely with a one-tap install, which is worth knowing if you’ve ever fumbled a scan at a service counter with spotty signal.
2. Leave the eSIM line on standby, not active, until you land — most plans start their validity clock the moment the connection first registers on a network, so activating early can burn a day of data before your flight even leaves.
3. Download the DiDi app (or, in mainland China, confirm the Alipay or WeChat mini-program works instead — more on that below) and complete registration on your home number.
4. Add a payment method. DiDi generally accepts Visa and Mastercard, and Alipay or Apple Pay in China. A declined card is far more often a “bank blocked an unfamiliar overseas charge” issue than a DiDi issue, so a quick heads-up call to your bank before you go saves a headache mid-ride.
5. Land, switch on the eSIM data line, and open DiDi. You should have a live map pin within a few seconds.

Country Quirks Worth Knowing

DiDi isn’t one uniform product everywhere, and a bit of local knowledge saves real friction:

• Mainland China runs on the separate DiDi Rider (Greater China) app, and it sits behind the same internet restrictions as everything else in the country. If you’re also running a VPN for Google Maps or Instagram, turn it off before requesting or paying for a ride — DiDi’s GPS accuracy and payment processing both work more reliably on a direct local connection than through a tunnelled one.
• Brazil uses the 99 app rather than DiDi branding, though it’s the same parent company and the same account infrastructure.
• Japan, Australia, and New Zealand run closer to a Western Uber-style experience: English interface by default, standard card payment, no separate mini-program needed.
• Across Latin America, cash is still accepted in more cities than in East Asia, so it’s worth having small local notes as a backup if a card gets flagged mid-trip.

How Much Data DiDi Actually Uses

This is one of the most searched, least clearly answered questions, so here’s a straight number: a typical DiDi session — opening the app, requesting a ride, and tracking it to arrival — runs somewhere around 5–10MB. Even a full day of moderate ride-hailing plus maps and messaging rarely clears 150–200MB. A 1GB eSIM plan comfortably covers several days of DiDi use on its own; the real data budget-killer is usually video streaming or social media scrolling layered on top, not the ride app itself.

Quick Troubleshooting

Problem	Most likely cause	Fix
No ride requests going through	eSIM data line not yet switched on, or still on standby	Check Settings > Mobile/Cellular and confirm the travel line is active
Verification code never arrives	Data-only eSIM has no SMS capability	Use your home SIM’s number for the code, or a dual-SIM setup
Driver can’t find your pin	GPS drifting from Wi-Fi-based positioning indoors	Step outside or near a window before confirming pickup
Card payment declined	Bank fraud filter flagging an overseas charge	Call your bank ahead of the trip, or add a backup card in-app
Route or fare looks inflated	Happens occasionally on longer intercity trips	Cross-check against Google Maps’ estimated distance before confirming

The Bottom Line

DiDi is one of the more dependable ride-hailing options across a genuinely wide stretch of the world now, and pairing it with an eSIM is the simplest way to make sure it works the moment you land — not twenty minutes and one failed pickup later. The eSIM choice matters less than people assume; the verification step is what actually trips travellers up, and it’s solved in under a minute if you handle it before you fly rather than after.

I write BazTel’s destination guides, including our China, Japan, Vietnam, Singapore, South Korea, Malaysia, Thailand, Philippines, and Egypt eSIM pages, and I test most of these setups myself before they go live. BazTel plans install with a single tap — no QR scanning required — and start from $1 across 160+ countries.

FAQ

Does DiDi work with a data-only eSIM?

Yes, for data. But a data-only line usually can’t receive DiDi’s SMS verification code, so register your account on a number that can take texts before you switch to data-only for the trip itself.

Which countries can I use DiDi in?

As of 2026: China (Greater China app), Hong Kong, Mexico, Brazil (as 99), Colombia, Chile, Peru, Costa Rica, Panama, Ecuador, the Dominican Republic, Argentina, Australia, New Zealand, Japan, Egypt, Singapore, Vietnam, Malaysia, Thailand, the Philippines, South Korea, Indonesia, and Cambodia.

Is DiDi available in the United States?

No. DiDi does not currently operate in the US — Uber and Lyft remain the main options there.

How much eSIM data do I need for a week of DiDi use?

Roughly 1–2GB comfortably covers a week of ride-hailing, maps, and messaging combined for one traveller.

Should I turn off my VPN to use DiDi in China?

Yes, while requesting or paying for a ride. Running a VPN alongside DiDi in mainland China can interfere with GPS accuracy and payment processing.
