Shanghai eSIM and SIM Cards: What Works for Foreigners (2026)

Mobile data is not a luxury in Shanghai. You need it for maps, translation, metro QR codes, payment, ride-hailing, and restaurant menus. Without it, even a short trip becomes unnecessarily difficult.

You have two main options: buy a travel eSIM before you arrive, or get a local SIM card from a Chinese telecom operator. Each has real trade-offs. This guide explains them, along with Wi-Fi, registration, and the apps you should install before you land.

Option 1: A travel eSIM

A travel eSIM is a data plan you install on your phone before you travel. It is sold by international providers, not by Chinese carriers, and it is the easiest option for a short trip if your phone supports eSIM.

Advantages:

• No store visit. You can buy and install it before you board.
• No passport registration at a counter. Your provider handles the plan.
• Immediate data on arrival. Switch it on when you land.
• Useful for short trips and for keeping your home number active for messages.

Trade-offs:

• Data only. Most travel eSIMs do not give you a Chinese phone number, so you cannot make local calls or receive SMS verification codes.
• Provider-dependent network. Speed, coverage, and restrictions vary.
• No local support in China if something goes wrong.
• Phone compatibility. Your phone must be unlocked and eSIM-capable.

Some travel eSIMs route data through servers outside mainland China, which means some apps that are blocked on local networks may work. This is not guaranteed and depends on the provider. Check the terms rather than assuming.

Option 2: A local SIM card

A local SIM from China Mobile, China Unicom, or China Telecom gives you a Chinese phone number and local data. It is the better option if you are staying longer, need SMS verification for local services, or use a lot of data.

The official Shanghai guide explains the offline process:

1. Go to a major operator store; many are in malls.
2. Choose a mobile package, or point to the brochure of plans.
3. Show your passport.
4. Show the SIM card size you need: normal, micro, or nano.
5. Buy and register the SIM.

Registration is mandatory and tied to your passport. The store staff will handle the paperwork, but you must be present with your original passport.

Advantages:

• A Chinese phone number for calls and SMS verification.
• Local data plans that can be cheaper for heavy use.
• Better integration with local apps and services.
• In-person help at the store.

Trade-offs:

• You need to visit a store and may wait in a queue.
• Your phone must accept a physical SIM, or support the operator's eSIM service.
• Registration takes time.
• Local network restrictions apply.

Nihao Mobile: a SIM delivered to you

The official guide also describes Nihao Mobile, an English-friendly service aimed at expats. It is a useful middle ground if you want a local SIM but do not want to find a store on arrival.

The process:

1. Download the Nihao Mobile app from the App Store or Google Play.
2. Choose a plan and add it to your cart.
3. Fill in your shipping information.
4. Pay; PayPal is accepted.
5. Orders placed before 6 pm on working days are dispatched the same day, with free delivery within 48 hours.
6. Follow the activation guide in English.

Activation requires:

• A photo of your passport's photo page.
• Your Chinese visa page.
• Your entry stamp page.
• A video selfie.

After activation, insert the SIM into the first SIM card tray, restart the phone, and you should have service. You can top up through Alipay, WeChat, or the operator's app.

The Nihao service is convenient, but it is a third-party product. Check the current plans, delivery area, and refund policy before paying.

Wi-Fi in Shanghai

Free Wi-Fi is available at many public places, including train stations, coffee shops, and convenience stores, according to the official Shanghai guide. Hotels usually provide Wi-Fi, though speed and reliability vary.

Do not rely on public Wi-Fi for sensitive logins or payments. Use your mobile data for banking and payment apps when possible. If you are staying in an apartment, home broadband requires a passport and a contract with one of the three major providers; that is not a short-term visitor option.

The network reality: some apps are blocked

Many foreign apps and websites are blocked on mainland Chinese networks, including Google services, WhatsApp, Instagram, and Facebook. This affects both local SIMs and hotel Wi-Fi. Travel eSIMs may behave differently depending on how the provider routes traffic, but do not assume any app will work.

Plan around this:

• Download offline maps and a translation app before you fly.
• Save your hotel address in Chinese.
• Install WeChat and Alipay and set up payment.
• Tell people at home that you may not be reachable on WhatsApp.
• Check your email access and have a backup way to receive verification codes.

Which option should you choose?

• Short trip (1–5 days), eSIM-capable phone: a travel eSIM is the simplest choice. Install it before you fly.
• Longer stay, need a local number: buy a local SIM from an operator store or use Nihao Mobile.
• Heavy data use, multiple devices: a local SIM with a hotspot is usually the best value.
• Travelling with family: one local SIM with hotspot can keep everyone connected, but check the plan's hotspot limits.
• Business travel: a local number is useful for calls and verification; keep your home eSIM active for messages.

Set up before you land

• Unlock your phone if it is carrier-locked.
• Check eSIM compatibility in your phone settings.
• Install the eSIM while you have reliable home Wi-Fi.
• Download maps, translation, and payment apps.
• Save your hotel's Chinese name and address.
• Carry your passport for SIM registration.
• Bring a SIM ejector tool if you use a physical SIM.

Common mistakes

• Buying an eSIM that only works in Hong Kong or Macau. Check that mainland China is covered.
• Assuming a data-only eSIM gives you a phone number. It does not.
• Forgetting passport registration for a local SIM.
• Relying on hotel Wi-Fi for everything. It may be slow or restricted.
• Not testing payment apps before arrival. Some cards are not accepted.
• Using a VPN without understanding the rules. Do your own research.

The bottom line

For most short-term visitors, a travel eSIM installed before departure is the easiest way to get online in Shanghai. If you need a Chinese number or plan to stay longer, get a local SIM from an operator store or Nihao Mobile. Set up your apps, download offline maps, and expect some services to be blocked. Connectivity is manageable if you prepare before you land.
