Quick answer For most visitors to Hainan, a travel eSIM installed before you fly is the simplest option: it connects when you land at Haikou or Sanya, needs no registration, and usually keeps Google and WhatsApp working. If you also need a Chinese phone number, register a China Mobile SIM with your passport at a service hall in Haikou or Sanya, or order a tourist SIM that includes one. The whole island shares the 0898 area code and the 0898-10086 hotline.

Getting Connected in Hainan: What to Know First

Hainan is an island province, so one mainland China plan covers the whole island, and travelling between Haikou in the north and Sanya in the south doesn't normally add roaming charges. Most visitors arrive through Haikou Meilan International Airport (HAK) or Sanya Phoenix International Airport (SYX), and the island's rail loop links the two cities. Signal is strongest in the cities, along the coast and around the resort areas; the mountainous interior can be patchier.

Hainan's free-trade port status is mostly about trade and tax, not about SIM cards. Visitors still follow the usual rules: your passport is needed to register a local SIM, and a local China Mobile SIM sends your data through mainland networks. If a counter offers a Hainan-local package, ask what it includes before you pay.

Five Ways to Get Connected

Which should you pick? Under a week and only need data: a travel eSIM. Any trip where you need a Chinese number for delivery apps or verification codes: a tourist SIM with a number, or a China Mobile SIM from a hall. A month or longer: register at a hall. Just a day or two and happy to pay for convenience: roaming on your home SIM.

Easiest for short trips

Travel eSIM

Install a travel eSIM at home, and your phone has data the moment you land at Haikou Meilan (HAK) or Sanya Phoenix (SYX). There is nothing to register and no queue to join. Travel eSIMs are normally data-only, so you won't get a Chinese phone number, but they usually route traffic outside the mainland, which keeps Google, WhatsApp and Instagram working. Holafly is my Editor's Pick for this.

Best if you also want a local number

Tourist SIM with a Chinese number

A prepaid tourist SIM that runs on the China Unicom network and comes with a real Chinese number. That helps with delivery apps, hotel and restaurant verification codes, and receiving SMS from local services. Order it before you fly so it is in your hand when you arrive; check the listing for how and when the number is activated.

Best for longer stays

China Mobile SIM from a service hall

Walk into a China Mobile hall in Haikou or Sanya with your passport, choose a prepaid plan, and the staff register the number in your name on the spot. It is the cheapest way to run a Chinese number for weeks rather than days, and the result is a normal local SIM. Expect Chinese-language paperwork and, outside the biggest halls, little English. Sanya's halls are listed hall by hall in the directory below.

Convenient, but check the bill

Roaming on your home SIM

Switching on international roaming needs no setup, and you keep your own number. The trade-off is cost: roaming day passes are often pricier than a local option, and your data typically exits through your home network, which also means your usual apps work. It suits a short trip where you only need a few hours of data a day. Check your carrier's China rates before you rely on it.

For verification codes and top-ups

Chinese number without a SIM

If all you need is a Chinese number that can receive verification codes, or a way to top up a number you already own, you can do it online without visiting a hall. My guides cover receiving Chinese SMS online and recharging China Mobile numbers from overseas.

Plans & Top-Up

The eSIM rows show Holafly's published China prices: unlimited data on the China Mobile network, plus a small 1GB-a-month backup allowance. Physical SIM figures are typical Chinese prepaid ranges rather than Hainan-specific quotes, so confirm the price at the counter.

For shorter or longer stays, Holafly's China eSIM also comes as 3 days (US$11.90), 5 days (US$20.50), 10 days (US$36.50) or 30 days (US$73.90). Compare all durations. If you only need to recharge an existing China Mobile number, use the top-up guide.

Hainan Cities and Where to Find Service Halls

One hotline covers the island: dial 0898-10086, or 10086 from a China Mobile number. Sanya has a full hall directory here. Elsewhere I describe what each place is known for, rather than guess at hall addresses I haven't verified.

Haikou

Hainan's capital and the northern gateway. Haikou Meilan International Airport (HAK) is here, and the city has four districts: Xiuying, Longhua, Qiongshan and Meilan. A dedicated Haikou hall directory is not on this site yet.

Sanya

The southern resort hub and the other main airport, Sanya Phoenix International (SYX). I've built a full hall-by-hall directory: 20 China Mobile halls across 4 districts.

Qionghai and Boao

On the east coast, Qionghai is the base for Boao, known for the Boao Forum. Smaller county-level halls handle most needs here, so bring your passport and be ready to use a translation app.

Wanning

East-coast beach and surfing towns such as Riyue Bay and Shimei Bay. Visitors usually arrange data in advance rather than relying on a hall.

Wenchang

Home of the Wenchang spaceport on the northeast coast. Fewer foreign visitors come through, so I wouldn't count on English at the counter.

Danzhou

In the northwest, on the western rail line. A quieter stop on a loop around the island.

Lingshui

South-east coast, between Wanning and Sanya, with a growing resort and island-tour trade.

Wuzhishan

Mountainous interior. Coverage tends to be patchier away from towns, so don't rely on a single signal for navigation up there.

Hainan SIM Card FAQ

Should I buy a SIM or eSIM before flying to Hainan?
If you want data the moment you land at Haikou Meilan or Sanya Phoenix, buy a travel eSIM before you leave home and install it on Wi-Fi. If you also want a Chinese phone number, either order a tourist SIM that includes one or register a China Mobile SIM at a service hall with your passport after you arrive.
Do I need to register a travel eSIM in China?
Normally no. Travel eSIMs are sold outside China and don't ask for Chinese real-name registration, which is why they work the moment you land. A local SIM, whether from a China Mobile hall or a tourist SIM with a Chinese number, does need your passport for registration.
Can foreigners buy a China Mobile SIM in Hainan?
Yes, but you need your passport for mandatory real-name registration. Haikou and Sanya have the busiest halls and the most experience with overseas visitors. Smaller towns can handle it too, though staff may have less English, so a translation app helps.
Will Google and WhatsApp work on a local China Mobile SIM in Hainan?
Usually not. A local mainland SIM sends your data through domestic networks, so Google, WhatsApp and Instagram are normally blocked. Travel eSIMs typically route data abroad, which avoids the problem, and a VPN installed before you arrive is the other common workaround.
How much does a SIM card or eSIM cost for Hainan?
On the figures in the plans table, a 7-day unlimited eSIM is about US$27.50 and a 15-day plan about US$50.50. A 30-day physical SIM with a Chinese number is typically around ¥150–200 and a 60-day SIM around ¥500. These are typical rates, so confirm the price before you buy.
What is the China Mobile hotline and area code in Hainan?
All of Hainan uses the 0898 area code. From a China Mobile number you can dial 10086, or use 0898-10086 from other phones. Don't count on English support; the 中国移动 app and a translation app are more dependable for account tasks.
Will one SIM work across the whole island?
Yes. Hainan is covered as one province, and moving between Haikou, Sanya and the east coast on a mainland China plan normally carries no extra roaming charge. Coverage is strongest in cities and resort areas and can be weaker in the mountainous interior.
Where can I find China Mobile service halls in Hainan?
For Sanya, use my directory of 20 halls across 4 districts, with addresses and opening hours. Haikou does not have its own directory on this site yet; for now, search for 中国移动营业厅 in a map app or call 0898-10086 to confirm the nearest hall and its hours.
