SIM Cards and Mobile Plans
Prepare the right identification, compare operators carefully, and protect your new Chinese number.
A Chinese SIM card should be treated as both a communications service and an identity-linked account. The Shanghai government education FAQ states that China requires real-name registration for anyone activating a SIM card, and it advises applicants to bring a passport or a photocopy of the passport. For an English-speaking student, immigrant, or future resident, this means that preparing the document is part of the China SIM card purchase process, rather than something to handle after the number has already been issued. Keep the passport details consistent with the name you intend to use for other important services, and bring the original document when possible because the supplied guidance specifically mentions a passport or photocopy, not another substitute. The source does not provide a nationwide list of activation locations, opening hours, prices, data allowances, or eSIM rules, so those details should be confirmed directly with the operator before payment. Start by asking for the plan’s real-name registration procedure, the exact monthly charge, included data, voice allowance, SMS allowance, renewal date, and cancellation conditions. The official guidance on how to get a SIM card in China is therefore most useful as a preparation checklist: passport ready, registration completed, and the written plan terms checked before you rely on the number for study, housing, banking, or travel.
The supplied sources identify China Mobile, China Unicom, and China Telecom as the three major telecommunications operators relevant to international connectivity. A government guide to making phone calls in China explains that when calling a Chinese mobile number from abroad, you first dial the international prefix, then 86, and then the mobile number. This makes it sensible to record your number in two forms: the domestic form shown by the operator and the international form needed by people calling from outside China. The source material does not give enough evidence to rank one operator as universally best, nor does it provide comparable nationwide prices or network coverage tables. Instead of choosing only by brand familiarity, ask each provider for the same facts in writing. Request the monthly price, the included data amount, the price or rule after the allowance is used, whether unused data expires, the voice and SMS limits, the minimum commitment, the activation charge, the payment method, and the process for suspending or cancelling the line. A comparison is meaningful only when the units and billing period are identical. For example, a package described as “large data” cannot be compared responsibly with another package until both providers state the exact amount and renewal conditions. The official China calling guide gives the international dialing sequence, while the provider list in the China internet service provider category confirms the operator names appearing in the supplied source context.
For a move planned three to six months ahead, divide the SIM decision into a temporary arrival phase and a longer residence phase, but do not assume that the source data proves a particular temporary product exists. The supplied community material mentions travel eSIMs and prepaid packages, but those community snippets are restricted to the FAQ array and cannot be used as evidence for the main section. For the main guide, the defensible procedure is to ask the operator whether a short-term prepaid option and a longer monthly contract are available to a foreign passport holder, then compare the exact written terms. Confirm whether the line can be renewed from outside China, whether payment requires a Chinese bank account or another method, whether the number remains active when you travel, and whether a change of passport information requires an update. The government guide says that a foreigner who changes passports or other items recorded on a residence permit must apply to the exit and entry administration authority for an information update within 10 days from the date of the change. That rule concerns immigration records rather than SIM contracts, so it should not be treated as proof of a telecom procedure; however, it is a useful reminder to keep identity information synchronized and to ask the carrier what it requires after a passport change. Keep the activation receipt, contract, registration confirmation, and customer-service contact together. If a staff member explains a condition verbally, ask for the same condition in the plan documentation before accepting it. This approach is especially important because the source context does not provide official China mobile phone rates or a complete comparison of data plan options.
A Chinese mobile number can become a target for social engineering, so privacy should be part of the setup process. The Hong Kong Police Anti-Deception Coordination Centre warns about callers pretending to represent the China Internet Illegal Information Reporting Centre, transferring the call to fake mainland law-enforcement personnel, and demanding personal details, bank-account numbers, passwords, deposits, or processing fees. The warning says that even when a caller knows personal information or sends a document containing your photograph, that does not prove the caller is genuine. For a newly arrived resident, the practical rule is simple: do not disclose passwords, payment information, or identity details to an unexpected caller who creates urgency. End the call and verify the organisation independently through a trusted official channel. The same source recommends checking the caller’s identity with the relevant institution and provides the “Scameter” hotline 18222 for enquiries. This is not a telecom pricing rule, but it matters when choosing how widely to share a new number and how to respond to calls or messages about alleged registration problems. Store the operator’s official support route separately from links sent in unsolicited messages, and do not treat a caller-ID display as proof of identity. The anti-scam warning records a specific pattern involving requests for account information and money, so keep your SIM registration paperwork available for legitimate verification while refusing unexpected demands.

Internet and WiFi Services
Plan home connectivity separately from mobile data and use public, campus, and personal WiFi cautiously.
China internet service should be planned around the place where you will live, because the supplied sources do not provide a universal national broadband price, speed table, installation timetable, or contract comparison. The available provider category lists China Mobile, China Mobile Tietong, China Netcom, China Telecom, China Telecommunications Corporation, China Unicom, 263.net, and Northcom Group, while noting that the category may not reflect recent changes. The list is useful for recognising names, but it is not a current offer sheet and should not be used to claim that every provider serves every building. Before signing a home internet contract, ask the landlord, accommodation office, or provider which companies can actually connect the address. Request the exact monthly fee, one-time setup cost, minimum term, equipment charge, deposit, renewal rule, payment method, and cancellation procedure. Also ask whether the service is a dedicated home connection, a shared building service, or an arrangement supplied by the residence. The source context contains no figures that support a reliable “China internet WiFi service” price comparison, so do not rely on an attractive headline price without checking the complete billing terms. For students, ask whether the university supplies campus internet separately and whether the school permits residents to add their own router. The provider names in the China ISP category offer a starting vocabulary for comparison, not a guarantee of availability, performance, or cost at your address.
Campus WiFi requires a different checklist from home broadband. A campus network safety guide from Guangzhou University of Chinese Medicine explains that wireless networks are essential for study and office work, but it warns that attackers can create a hotspot with the same or a similar name as a familiar WiFi network. The guide describes blank-password or same-password hotspots that attract users, DNS hijacking that redirects users to phishing sites, and monitoring that can expose passwords sent in plain text. Its first practical instruction is to confirm the hotspot name with the business or organisation providing the WiFi. It also advises caution with passwordless public WiFi, especially networks with strange names, and recommends using a carrier’s 4G/5G network when using payment apps. Turn off the phone or laptop’s wireless function when WiFi is not being used. These steps are useful when arriving at a university, renting a room, working in a café, or using an airport connection. Do not assume that a familiar-looking network name is genuine, and do not allow a device to reconnect automatically merely because it has saved a password. Check the network name before connecting, avoid sensitive payment activity on an unverified network, and return to mobile data when the task involves payment or account credentials. The campus WiFi safety guide gives these recommendations directly and does not require you to know a particular router brand or internet provider.
If you need a personal hotspot, treat the phone as a temporary access point rather than leaving it open all day. The campus safety guide explains that devices connected to a personal hotspot can potentially access websites visited, messages sent, and files downloaded through the device. It recommends opening the hotspot only when necessary and closing it immediately after use. Use a strong password, permit only trusted devices, and check the connected-device list regularly. The guide also advises checking for suspicious activity on both the phone and connected devices. This is especially important when a student shares a connection with a laptop, tablet, or another phone in temporary accommodation. A hotspot can help when home service is not yet active, but the supplied sources do not provide a price comparison between mobile data and fixed broadband, so calculate the cost using the operator’s written allowance and overage terms rather than assuming one option is cheaper. Do not use a private router on campus without permission: the same guide cites Guangzhou University of Chinese Medicine’s network security management rule that no unit or individual may privately build, change, damage, or misappropriate campus network facilities. It says unauthorised additional routers may disrupt the overall network layout, lower stability, affect other users, and create information-leakage or network-attack risks. If a department has a special campus wireless requirement, the guide says it should apply to the information centre for evaluation and deployment. Follow the school network recommendations before installing equipment.
Public WiFi should be considered an exposure risk, particularly for online banking, shopping, or account recovery. Human-IT states that public networks do not encrypt data sent to you, meaning that another person on the same network may be able to intercept it. Its practical recommendations are to disable file sharing, enable the device firewall, keep antivirus and malware protection updated, and use a VPN to encrypt data where possible. It specifically says that a VPN encrypts data through a tunnel, while a firewall monitors and blocks unauthorised access; these are different protections and can be used together. For sensitive transactions, the page advises using a VPN and checking that the website uses HTTPS, while identifying a secure private network as the better option. It also warns that many free VPN services may profit from user data and recommends a reputable paid service with a transparent privacy policy. These are general security recommendations, not a China-specific legal or service guarantee. The page itself warns that some information may be outdated, so verify current tool availability and applicable rules before relying on a particular product. In China, international connectivity may also be affected by network filtering. The source describing the Great Firewall says that systems analyse and filter overseas internet information and may interfere with, block, or screen transmissions considered inconsistent with official requirements. Plan essential study, work, and communication through services you have tested legally and securely before an urgent deadline.

Mobile Phone Rates and Contracts
Compare total contract cost, data rules, identity requirements, and international connectivity before signing.
The supplied source data does not contain a complete official table of Chinese mobile phone rates, so a responsible China mobile plan comparison must begin with the provider’s current written quotation. Do not fill the gap with invented prices or assume that a package described as affordable has the same meaning across operators. Ask for a line-by-line statement covering the monthly charge, included data, voice minutes, SMS, activation or registration charges, equipment charges, minimum contract period, renewal date, payment method, and the price or restriction that applies after the included allowance is used. Ask whether the displayed amount includes every mandatory fee and whether a different price applies after a promotional period. Also ask what happens if you leave China, change accommodation, lose the SIM, or need to update your passport. A plan is not comparable until all providers answer the same questions using the same units and billing period. Record the answers in English for your own reference, but keep the carrier’s original wording because the contract controls the service. For a student, calculate the likely use separately for ordinary browsing, messaging, video, hotspot use, and payment applications, but do not claim a specific data requirement unless the provider or your own measured use supports it. For an immigrant or worker, ask whether employer reimbursement, international calls, or overseas server access is covered, because the source data does not say that a standard consumer package includes any of these. The official SIM activation guidance establishes real-name registration and passport preparation; it does not establish prices, so rates must be verified at the point of contract.
Contract setup should be separated into identity, residence, and telecom questions. For the SIM itself, the Shanghai government FAQ says that anyone activating a Chinese SIM must complete real-name registration and should bring a passport or passport photocopy. Separately, the central government’s Guide to Working and Living in China says that a foreigner staying in a hotel can have residence registration handled by the hotel by presenting a valid passport or other international travel document to reception. A foreigner staying elsewhere must register at the local police station within 24 hours after arrival, presenting a valid passport or other international travel document together with a rental contract or property ownership certificate. These are residence-registration requirements, not evidence that a telecom operator accepts every document or offers every contract type. Keep the processes distinct: prepare the passport for the SIM activation, and separately complete residence registration according to the accommodation situation. The same government guide says that a person entering China with a visa and planning to work and live there must apply for a residence permit within 30 days of entry, where applicable. It also says that an extension of the visa stay should be submitted at least 7 days before the stated duration expires, and that a residence-permit extension should be applied for 30 days before expiry. These dates should not be copied into a mobile contract as telecom deadlines, but they matter when choosing a contract length that will remain useful during your legal stay. If your passport or residence-permit information changes, ask both the relevant immigration authority and the carrier what update is required. The government living guide provides the immigration dates and residence-registration procedure.
International calling and overseas access need careful wording because the sources describe procedures and legal risks rather than current consumer rates. The government calling guide states that a caller reaching a Chinese mobile number from abroad should dial the international prefix, then 86, followed by the mobile number. Save that sequence in your emergency and family contact notes, and test the format with a trusted contact before you need it. The supplied material does not give the price per minute for international calls, the cost of roaming, or a list of countries included in any plan. Therefore, request those figures directly and ask whether they are charged per minute, per message, per unit of data, or under a separate add-on. The BBC article on VPN use reports that, according to the expert quoted in the 2019 article, only overseas-server connection services applied for through China Mobile, China Unicom, and China Telecom were described as lawful, while other forms of “circumvention” were discussed as illegal channels under the cited regulation. The article also reports a warning and a 1000-yuan administrative fine in one case, and says the cited regulation permits a maximum fine of 15000 yuan. Because that article was published in 2019 and describes an interview and reported enforcement context, it should not be treated as a complete statement of current law. It does show why a contract promising overseas access should be reviewed for legal basis, provider identity, and current official requirements. The BBC report also describes a case in which a phone connected to home broadband and a VPN application was used 487 times during the week before enforcement, illustrating that users should not assume ordinary personal use is automatically risk-free.
Before signing, make a short contract record and verify every operational detail that can affect your monthly bill. Write down the operator name, service number, registration name, activation date, renewal date, monthly charge, included allowances, payment method, cancellation route, customer-support route, and the treatment of a lost or damaged SIM. The source data does not supply a universal cancellation period, refund rule, transfer procedure, or number-retention policy, so do not assume that a foreign resident receives the same treatment as a local customer or that a number can be moved automatically between plans. Ask whether a passport update, residence change, or departure from China requires a new registration step. Keep proof of payment and the contract until the line has been cancelled or transferred successfully. Treat unexpected calls about a contract as suspicious when they demand a password, bank account number, immediate transfer, or processing fee. The Anti-Deception Coordination Centre warning says callers have impersonated reporting-centre staff, transferred victims to fake law-enforcement personnel, and demanded personal information, bank details, passwords, deposits, or fees. It advises checking the identity of alleged officials through the relevant institution and gives the “Scameter” hotline 18222 for enquiries. A legitimate contract review should happen through a channel you found independently, not through a link or number supplied by an unsolicited caller. If the carrier’s current offer differs from an online page, use the written contract and current official customer-service information as the basis for your decision. This discipline protects both your budget and the identity information attached to the mobile number, while recognising the source limitation that exact China mobile rates and contract terms are not included here.
