Shenzhen SIM Cards 2026: How to Choose Among the 3 Major Carriers' Border Checkpoint Shops — Real-Name Registration + Number Maintenance Guide

Many Hong Kong people think that using Hong Kong roaming when travelling north is enough, but as long as you want to do any of the following, you need a real-name registered mainland phone number: opening a mainland bank account (the bank will send a verification code to your mainland number), registering for WeChat Pay / Alipay (mainland version), receiving verification codes for Meituan / Dianping / Didi / 12306, making restaurant reservations, and providing a contact number for hotel check-in. Simply put, a mainland number is "the key to life up north."

The Three Major Carriers: How to Choose?

Mainland mobile phone services are provided by three state-owned carriers, all of which require real-name registration:

• China Mobile (customer service hotline 10086) — the widest coverage, usually the most stable signal in suburbs, by the sea, and in mountainous areas, and the most flagship stores at checkpoints and shopping malls;
• China Unicom (10010) — good speeds in urban areas, and some plans have cheaper data;
• China Telecom (10000) — a high market share in fixed-line broadband, and sometimes there are bundle discounts when you get mobile and broadband together.

Prepaid cards from all three can receive SMS verification codes and can all be real-name registered. The main differences are in monthly fees, data, and shop locations. Coverage is good for all three in urban areas, so there's no need to agonise over it.

Three Ways for Hong Kong Residents to Get a SIM Card

① Border Checkpoint Shops (Get It Done On the Spot)

The most direct way: get your card at an official shop near the checkpoint after crossing the border. Bring your original Home Return Permit (some stores will ask for a photocopy). Staff will photocopy your document, take your photo, do facial recognition, and activate it on the spot.

② Urban Shops (Most Choices)

The large flagship shops of the three major carriers in urban Shenzhen have the fullest stock and plan selection, so you can compare at leisure. For example, the Huaqiangbei area has the highest density of stores, and sales staff are familiar with the SIM card process for Hong Kong residents.

③ Hong Kong "One Card, Two Numbers" (No Need to Cross the Border)

Hong Kong telecom providers offer a "One Card, Two Numbers" service, adding a mainland secondary number to your Hong Kong number, with the monthly fee paid in Hong Kong. The downside is that some mainland apps (especially financial ones) still require "real-name verification with a mainland number," so it may not be fully compatible.

Real-Name Registration: You Must Bring Your Home Return Permit in Person

• Real-name registration is required by mainland law and must be done in person, bringing your Home Return Permit (Mainland Travel Permit for Hong Kong and Macao Residents) original;
• Process: staff photocopy your document → take your photo → facial recognition → activate on the spot;
• There is a limit to how many cards one Home Return Permit can register with the same carrier. Do not register on someone else's behalf, and do not lend your name for someone else to register a card;
• ⚠️ Do not buy "real-name registered cards" from small street shops or online agents — if the card is used for fraud, you will be implicated.

Where Is It Smoothest to Get One at the Three Checkpoints? (With Amap Navigation)

Luohu Checkpoint (Luohu Station, Line 1)

As soon as you exit through Exit A of Luohu Station on Line 1, there are China Unicom and China Mobile shops around the joint inspection building — the most direct option. There are also many telecom stores nearby in Luohu Commercial City and the Dongmen area.

Futian Checkpoint (Futian Checkpoint Station, Line 4)

Around Futian Checkpoint Station on Line 4 and Convention & Exhibition Center Station on Lines 1/4, there are many office buildings and shorter queues at stores. While getting your card, you can also visit Futian COCO Park and the malls around Excellence.

Shenzhen Bay Checkpoint (Shenzhen Bay Checkpoint Station, Line 13)

Cross the border at Shenzhen Bay Checkpoint Station on Line 13 and head to the Nanshan Coastal City and Shenzhen Bay MixC area. The malls are new and less crowded, suitable if you want to get it done quickly and leave.

⚠️ Shop opening hours usually do not completely match checkpoint opening hours. Some checkpoint stores only operate during the day. It is best to check the store's opening hours for that day before setting off, or choose to cross during the day to get it done.

Monthly Fees and Plans: Don't Buy the Most Expensive for Data

If you only go north for weekend shopping, you don't need a large monthly plan. When choosing a card, keep a few things in mind:

• Cheap enough monthly fee: Some mainland carriers offer low monthly fee "number-keeping plans" (commonly around the ¥8 level), which is enough for receiving SMS verification codes;
• Data allowance: If you mainly use Hong Kong data roaming, the mainland card is mainly for receiving SMS, so a basic plan is enough;
• Calls: If you occasionally need to call for a ride or make a reservation, you can choose one with a small number of call minutes;
• Number portability: Mainland numbers are portable, so you can keep your number if you want to switch carriers later.

Actual monthly fees and offers are subject to the shop's quote on the day. Before getting one, ask clearly whether there are new customer offers or a free first month.

Money-Saving Tips for Maintaining Your Number

• Switch to the cheapest number-keeping plan — if your number is suspended for more than a certain period, it may be deregistered;
• Link WeChat Pay / Alipay for automatic monthly fee deduction to avoid suspension due to arrears;
• If you renew your Home Return Permit, remember to go to the shop to update your real-name information;
• If you no longer use it, go to the shop to cancel it. Arrears will affect getting a card again later.

FAQ

Can I get a mainland phone card without a Home Return Permit?

Real-name registration must use a valid document (Home Return Permit or Hong Kong and Macao Residents' Residence Permit). In some cases a passport can be used, but most are limited to specific plans. It is recommended to bring your Home Return Permit directly to an official shop.

Can one card receive both Hong Kong and mainland SMS at the same time?

With "One Card, Two Numbers" you can; if they are two separate cards, you will need a dual-SIM phone or carry two devices.

Will I receive SMS on the day I get the card?

Prepaid cards from official shops are generally activated on the spot and usable immediately. After activation, it is recommended to test a call and receive a test SMS on the spot, and only leave once you confirm there are no issues.

Do checkpoint shops require an appointment?

Generally you can just queue on the spot. It is busier on holidays. Subject to each carrier's store announcements.

Monthly Fee Tiers: Starting with the "Number-Keeping Plan"

All three major mainland carriers have minimum-spend plans, commonly known as "number-keeping plans" — mainly for keeping your number and receiving SMS verification codes, not for data:

• China Mobile: The commonly mentioned "8 yuan plan" (the lowest tier of the 4G Feixiang series), generally you can choose a small amount of calls or a small amount of data per month.
• China Unicom: Also has an 8 yuan low monthly fee number-keeping plan, with some tiers including a small number of call minutes.
• China Telecom: Has a 5 yuan tier commonly known as the "Wuyou Card," focused on long-term number keeping with very little data.

Note that in recent years these low-tier plans often require you to "ask proactively, or even complain, to get them," and different stores handle it differently. Detailed monthly fees, whether you can newly apply, and whether there is a contract period are all subject to the latest announcements at the carrier's official shops. If you plan to keep a number long-term to receive verification codes, the most practical thing is to tell staff directly, "I want the cheapest number-keeping plan."

Shops do business during the day, so even if the checkpoint is still open at night, the stores have already closed — don't think you can cross the border in the early hours to get a card.

FAQ Supplement

Do I need a residence permit to get a card? Not necessarily. A Home Return Permit is enough for real-name registration; if you have a Hong Kong and Macao Residents' Residence Permit, some stores will have smoother plan choices and activation procedures.

How many cards can I get with the same carrier? There is a quantity limit (depending on carrier policy), and each card must be registered in person under your real name. Do not open cards to "help a friend" — if the card is used for fraud, you will be held responsible.
