You need to first understand the specific reason why the account was frozen. Banks usually take measures based on telecom fraud risk control mechanisms. You can check the freezing explanation through bank customer service or online banking. Different banks adopt different freezing methods according to risk levels and legal requirements. The table below summarizes common bank freezing reasons and their impacts:
| Main Reason | Impact |
|---|---|
| Only freeze the disputed amount | Prevents innocent accounts from being completely frozen and protects user funds. |
| No longer freeze the entire account by default | Reduces impact on normal business and salary payments. |
| Requires police or court order to freeze | Ensures the legality and fairness of freezing actions. |
| Establish appeal mechanism and time limits | Increases transparency and protects user rights. |
| Emphasize proportionality principle and livelihood protection | Prevents fraud while safeguarding citizens’ and business rights. |
You should pay attention to the appeal mechanism and time limits, and prepare appeal materials promptly. Under telecom fraud risk control, banks prioritize protecting user fund safety while also safeguarding your normal life and business operations.
You need to prepare identity and fund-related proofs in advance. When investigating telecom fraud risks, banks usually require you to provide the following materials:
These materials help the bank verify your identity and source of funds. You should ensure the materials are authentic and complete to facilitate quick verification by customer service.
Banks will require you to explain your occupation and fund usage. You can organize relevant documents in advance for accurate communication during the phone call. The table below lists common occupation and fund usage proof documents and their purposes:
| Required Document Type | Purpose |
|---|---|
| Employment contract | Prove the legitimacy of fund source |
| Payslips | Prove the legitimacy of income and funds |
| Tax returns | Prove legitimacy of income and tax compliance |
| Commercial invoices | Prove legitimacy of transactions and fund usage |
| Property sale contracts | Prove legitimacy of fund source |
| Inheritance documents | Prove legitimacy of fund source |
| Investment account statements | Prove legitimacy of fund source |
| Communication records with transaction counterparties | Prove legitimacy of transactions and fund usage |
You should prepare corresponding documents based on your actual situation. Clearly explaining the source and usage of funds helps the bank determine whether your account is involved in telecom fraud risks. Organizing occupation information and fund usage in advance can improve unfreezing efficiency and reduce the risk of misjudgment.

When calling bank customer service, first introduce yourself and proactively cooperate with identity verification. You can follow these steps:
Tip: The identity verification stage is an important measure for banks to prevent telecom fraud. You should patiently cooperate and ensure all information is authentic and consistent.
After passing identity verification, you need to concisely explain the account freezing situation. It is recommended to:
You can say: “Hello, I found that my account has been frozen. Please assist in checking the specific reason. I am willing to cooperate with the relevant investigation.” This is both concise and demonstrates your cooperative attitude.
After explaining the situation, you should proactively ask about the unfreezing process and required materials. Common processes include:
Recommendation: Organize all proof materials in advance, actively cooperate with the bank’s due diligence investigation to improve unfreezing efficiency.
When communicating with bank customer service, clear and standardized expressions can effectively improve unfreezing efficiency. It is recommended to prepare the following standard scripts in advance for smooth communication at different stages:
You can flexibly adjust expressions according to the actual situation. Maintaining a calm tone and sincere attitude helps bank staff understand your request more quickly. Taking Biyapay as an example, many Chinese-speaking users successfully complete identity verification and material submission when encountering account risk control by using the above standard scripts, improving unfreezing efficiency.
Friendly reminder: Avoid emotional expressions during communication and focus on facts and willingness to cooperate to effectively reduce misunderstandings.
When banks investigate telecom fraud risks, they focus most on the legitimacy of fund sources and usage. You need to explain the origin and destination of each fund in concise and standardized language. The following are common standardized explanation methods:
When explaining, avoid vague statements such as “friend loan” or “temporary income”. It is recommended to collect and retain all transaction proofs, including bank statements, transfer screenshots, contracts, invoices, chat records, etc. In complex situations, you can submit a written statement to the bank detailing that you have not participated in any telecom fraud activities. If necessary, you can hire a qualified cybercrime lawyer to assist in submitting statements to investigators and the bank.
If your fund movement genuinely involves cross-border transfers, family support, or later-stage asset arrangement, your explanation to the bank should still stay focused on clear purpose, traceable routes, and records that match each step. You can first review the official information on the BiyaPay website, then organize records related to its remittance service or currency converter and comparison tool so that fund usage, currency conversion, and timing remain consistent. As a multi-asset trading wallet, BiyaPay covers cross-border payments, investing, trading, and fund management scenarios, and it discloses relevant registrations and licensing information such as US MSB and New Zealand FSP. That kind of public information is better used as supporting background to make your explanation more complete, rather than as a substitute for the bank’s own review.
Standardized and truthful fund explanations help banks quickly assess account risk and reduce the probability of misjudgment.
When communicating with the bank, be very careful with wording to avoid triggering the telecom fraud risk control system. The following are common sensitive words and suggested replacement expressions:
| Sensitive Word | Suggested Replacement Expression |
|---|---|
| Investment, wealth management | Fund management, asset allocation |
| Lending, borrowing | Fund transactions, family/friend support |
| Virtual currency, digital currency | Electronic assets, network assets |
| Quick returns, high yields | Normal income, business income |
| Online part-time job, brushing orders | Temporary work, short-term projects |
You should try to avoid directly mentioning the above sensitive words on the phone. Use more neutral and standardized expressions instead. For example, if you conduct cross-border fund management through Biyapay, it is recommended to state “for personal asset allocation or family expenses” instead of “investment” or “wealth management”. This can effectively reduce the risk of being misjudged as telecom fraud.
Recommendation: Before communication, list all fund usages and sources, and sort them one by one using standardized expressions to ensure every item can withstand bank scrutiny.
When communicating with bank customer service, banks usually ask detailed follow-up questions regarding account fund flows, transaction background, and identity information. Common questions include:
The bank will judge the account risk level based on your answers. You need to organize your fund flows and transaction background in advance and prepare relevant proof materials.
When facing bank follow-up questions, stay calm and answer truthfully. You can refer to the following suggestions:
Tip: When answering, avoid using sensitive words such as “lending”, “investment”, “virtual currency”; try to use neutral expressions such as “salary income”, “business transactions”, “family remittance”. All materials and information should be authentic and complete—avoid exaggeration or concealment. This helps the bank quickly assess account risk and improves unfreezing efficiency.
When communicating with bank customer service, staying calm and polite is the foundation of efficient communication. Facing the pressure of account freezing, you can try deep breathing to adjust your emotions and avoid letting anxiety or anger affect your expression. Focus on the issue itself, actively listen to the customer service explanation, and demonstrate empathy and willingness to cooperate. The following methods help maintain a good mindset during communication:
Communicating with rationality and politeness helps the bank quickly understand your needs and improves unfreezing efficiency.
When explaining account fund sources and usage, insist on truthful and concise information. Over-explaining not only fails to build trust but may cause confusion or misunderstanding. The table below summarizes related risks:
| Evidence Type | Description |
|---|---|
| Importance | Providing clear and honest information is key; any inconsistency or incompleteness may prolong investigation time and trigger stricter scrutiny. |
| Risk of Over-Explaining | Over-explaining may cause confusion or misunderstanding, affecting account unfreezing efficiency. |
You only need to truthfully answer the questions raised by the bank and avoid proactively adding too many irrelevant details. This reduces unnecessary follow-up questions, helps the bank focus on core issues, and improves review efficiency.
After each communication with the bank, promptly record the details, including time, staff name, main questions, and key responses. This helps you follow up on progress and avoid missing information. You can refer to the following practices:
Through standardized recording and active follow-up, you can effectively protect your rights and promote smooth progress of the account unfreezing process.
During the account unfreezing process, you should follow these key steps:
Staying calm, expressing truthfully, and communicating in a standardized manner helps efficiently resolve risk control misjudgments and protect your rights.
After submitting complete materials, licensed Hong Kong banks usually complete the review within 3–7 working days. The actual time depends on the complexity of the investigation and the completeness of materials.
You should proactively cooperate with the bank’s investigation and provide proof of fund sources and usage. Maintain transparent communication and promptly supplement required materials to help quickly clear risks.
You can provide bank statements, transfer records, commercial invoices, or family remittance vouchers. As long as the fund flow can be clearly explained, banks generally accept it.
You should use the account in a standardized manner, avoid frequent large remote or cross-border transfers. Prepare fund proof in advance and communicate regularly with the bank to reduce the probability of misjudgment.
You can complain to the bank’s compliance department or the Hong Kong Monetary Authority. Retaining communication records and materials helps protect your rights.
