SIM Cards and eSIM for Under-18s in Beijing: What Parents Need to Know
China registers every phone number to a verified real person, and a minor cannot hold one alone. The age bands carriers actually apply, what a guardian must bring to a Beijing store, why a travel eSIM skips the whole process, and what each option costs.
12 min read · KOULING's Beijing Travel Guide
If you are travelling to Beijing with a teenager, at some point a counter clerk will tell you no. China registers every mobile number to a named, verified real person, and under Chinese civil law a 15-year-old cannot be that person on their own signature. The good news is that the fix is boringly simple: you either register the number in your own name and hand the SIM to your teen, or you skip the counter entirely and buy them a travel eSIM that needs no registration at all. This guide covers the age thresholds carriers actually apply, the documents a guardian must bring to a carrier-owned store in Beijing, why the eSIM route sidesteps the whole problem, what each option costs, and the two things that matter more than the paperwork: parental controls, and the fraud offence your teenager should never get near.
Why age matters at all: real-name registration
Every mobile number sold on the Chinese mainland is tied to a verified identity under the Ministry of Industry and Information Technology's Provisions on Registration of Real Identity Information of Telephone Users (Decree No. 25, in force since 1 September 2013). Since 1 December 2019 carriers must also run a live facial-recognition match against the ID document at the point of sale, so the person whose name goes on the account has to physically stand at the counter. For foreign visitors the accepted documents are a passport or a Foreign Permanent Resident ID Card, and MIIT guidance states plainly that a stranger cannot register a number for you. That last sentence is exactly why minors are a special case: a child cannot hold the registration, so the law substitutes the legal guardian for the holder. Everything below follows from that one substitution.
The age bands, and what each one can actually do
Carriers work from the capacity rules in the Civil Code, so the thresholds are national rather than store-by-store. Expect the clerk to ask your child's age as the first question, because it determines which of these four paths applies.
Under 8 — The guardian registers using their own original ID document. The child does not become the registered user at all; the number is effectively a parent's number in a child's phone.
8 to 15 (i.e. under 16) — The legal guardian must apply in person at a carrier-owned store, registering both their own identity and the child's, with the guardian's photograph taken and kept on site.
16 and 17 — Legally a minor with limited capacity. To hold a number in their own name they must prove their own earned income is their main livelihood, with social-insurance records, an employer-stamped income letter, or bank salary statements. Fail that, and the guardian applies instead.
18 and over — Full adult: own passport, own face, own signature, no guardian involved. There is no upper age limit either, so travelling grandparents register exactly like any other adult.
The 16-18 band in practice — Local carrier compliance rules reported in 2026 describe under-16s as unable to open a number independently and 16-18s as requiring a guardian present, a verified guardianship document, and a signed risk-disclosure letter. Assume this is what the Beijing counter will do.
What the guardian has to bring
Foreign families hit friction here not because the rules are hostile but because the clerk has probably never processed a foreign birth certificate. Bring more paper than you think you need, in paper form, and go to a large carrier-owned store rather than a small franchised shop, which will simply decline paperwork it has never seen.
Your passport — The original, not a copy and not a photo on your phone. It gets scanned and matched to your face.
Your teenager's passport — Also the original. The child is recorded as the user of the line even when you are the applicant.
Proof of guardianship — A birth certificate naming you as the parent is the clean version. If it is not in Chinese, bring a printed copy and, if you have one, a notarised translation. Where the adult is not a parent, bring the notarised guardianship document.
The handset — Bring the phone the SIM will go into. Staff check 5G and VoLTE compatibility, and a mismatch is one of the most common reasons a counter visit ends without a card.
Time — Budget 45 to 90 minutes. Carrier-owned stores run a ticket queue, and minor applications are rare enough that staff often escalate to a supervisor.
Bring the teenager — Not always demanded, but several stores ask for the child to be present for the photo record. Verify by phone before you go.
The shortcut almost everyone uses: put it in your name
Before you spend a morning on guardianship paperwork, consider not doing it. MIIT caps each user at five active mobile numbers per operator nationwide, which comfortably covers a family. So you can simply open a second number in your own name, with your own passport and your own face, and hand the card to your teenager. It is fully compliant, because the registration is real and accurate; it avoids every guardianship document; and it is what most Chinese parents do. The trade-off is that the line is legally yours: contracts, top-ups, and any carrier or police query come to you.
The cap — Up to five active numbers per person per operator, nationwide. A family of four is nowhere near it.
Why it is clean — Real-name registration exists to tie a number to a person. Yours is a real person, and you are present, so nothing about the process is irregular.
The catch — Your teen cannot later transfer the number into their own name without redoing the registration, and you carry responsibility for how the line is used.
Ten-number rule — If your numbers across all operators total 10 or more, new lines can only be handled by the store's own staff accounts. Irrelevant for a family, worth knowing for long-stay residents.
eSIM: the option where age is irrelevant
A travel eSIM bought from a non-Chinese provider is the single easiest answer for most teenagers. It is sold by a foreign carrier, routes through overseas networks, and never touches China's real-name registration system, so there is no age gate to trip over. It also happens to be the option that keeps Google, Instagram and WhatsApp working, because the traffic exits the mainland before reaching the open internet. If your teen has an eSIM-capable phone and does not need a local phone number, stop reading the SIM sections and buy one before you fly.
What it is — A data-only line from a non-Chinese provider such as Airalo, Holafly, Saily or Ubigi, installed by QR code before departure.
What it gets around — No passport scan, no facial recognition, no guardian, no store visit, no Chinese-language contract.
What it does not give you — No +86 number. That matters for shared bikes, some delivery apps, 12306 rail accounts, and a handful of SMS verification codes.
The hardware gate — The phone must be carrier-unlocked and support eSIM: iPhone XS or newer, recent Samsung and Pixel flagships. Many mid-range Android phones sold outside Asia do not.
Chinese eSIMs are different — eSIM products sold by Chinese carriers or by Chinese platforms still require passport real-name registration, which brings the age rules straight back. Check which kind you are buying.
Price ballpark — Roughly US$10 to US$25 for 5 to 15 GB valid 7 to 30 days. Verify current pricing before you buy.
Pocket Wi-Fi: one registration for the whole family
If more than one child needs data, or the phones are too old for eSIM, a rented pocket Wi-Fi is the lowest-friction option of all. You register once, in your own name, at an airport counter or through your hotel, and everyone connects to the same box. Expect roughly ¥30 to ¥50 per day plus a refundable deposit of around ¥500, with five to ten devices supported. The downsides are mundane but real: one more device to charge every night, and the moment a teenager wanders off with it, nobody has data.
When your teenager genuinely needs a +86 number
Data alone covers maps, translation, messaging and payments. A real mainland number unlocks the layer underneath, and the question to ask is not "does my teen need data" but "will my teen ever move around Beijing alone". If the answer is yes, the number is worth the counter visit.
Shared bikes — HelloRide and Meituan bikes are the cheapest way to cross a hutong neighbourhood, and registering generally wants a mainland number.
Rail bookings — A 12306 account for train tickets is far easier with a Chinese number for verification and notifications.
Delivery and waitlists — Food delivery apps and the QR waitlist systems many restaurants use send to a local number.
Being reachable offline — A driver, a guide, a museum education desk, or a homestay host will call or SMS a +86 number, not message you on WhatsApp.
If the answer is no — If you will be together the whole trip, a travel eSIM plus your own hotspot covers everything at a fraction of the effort.
At the counter: what actually happens
The process is the same at any of the three majors; China Unicom is often the easiest for foreign handsets because its network bands match more overseas phones. Carrier-owned stores are the only reliable venue for passport registrations, and in Beijing that means the large flagship branches rather than the small shop on the corner.
Take a ticket — From the machine by the door. Photograph the slip so you can ask someone later.
Open with one sentence — Show your passports and say you want a SIM card for your child. Staff will ask the child's age first, because it decides the paperwork.
Documents and photo — Your passport is scanned, the guardianship document is checked, and your photograph is taken and matched. Your teen's passport is recorded as the user.
Choose a plan — Tourist plans reported in 2026 include a China Unicom 30-day around ¥200 for 20 GB plus 30 minutes, a high-data 30-day around ¥300 for 100 GB plus 50 minutes, and downtown store options around ¥200 for 50 GB plus 300 minutes. Verify current pricing at the counter.
Pay and activate — Cash, Alipay, WeChat Pay or an international card. The first month is paid up front and the card is live before you leave the store.
Check the balance — Send YE to 10086 for China Mobile, 102 to 10010 for China Unicom, or 102 to 10001 for China Telecom. Prepaid lines stop working when the balance runs out.
Parental controls, and the one legal risk that is not about screen time
China's regulations on protecting minors online came into force on 1 January 2024 and push carriers to offer minors' modes. In practice all three majors sell parental-control features that limit usage by hour band, filter content and cap spending; several are free and can be switched on at the counter. Ask for them. The far more serious issue is the one Chinese police call the two-cards offence: under the Anti-Telecom Network Fraud Law, lending, renting or selling a phone card or bank card that is then used in a scam can bring detention, a fine and a criminal record, and police have repeatedly broken rings that paid teenagers to register SIM cards in their own names. Two rules for a foreign teenager cover almost all of it: never let anyone else put their SIM in another phone, and never register a number for a stranger for money.

If you found this useful, these cover the next question most families ask:
Do it before you board — Install and test a travel eSIM at home, where you have Wi-Fi and time. Debugging one on a jet-lagged teenager's phone at midnight is the worst version of this task.
Carry paper — Printed passport copies and a printed birth certificate. Clerks photograph and file paper far more willingly than they squint at a screen.
Dual SIM is the best setup — eSIM for data plus a local physical SIM for the +86 number, if the phone supports both. One device, both worlds.
Write the number down — Photograph the SIM packaging and the number itself. Recovery without it means another store visit.
Keep the registration honest — Never let a guide, a shop assistant or a new friend register a number nominally for your child. Liability follows the registered name.
If one store refuses — Go to a larger carrier-owned branch. Small franchised shops routinely turn away foreign paperwork they have not been trained on, and this is the single most common false alarm.
Unlocked handset, always — A phone still locked to a home carrier will accept no Chinese SIM at all. Check before you fly, because unlocking remotely can take days.
