Can you imagine the despair of having your Quark membership frozen overnight, while the linked Chinese mobile phone number has already been cancelled?
Things often happen at the most unexpected moments.
In mid-July 2026, after a version upgrade, the Quark App forced users to log in again using a mobile phone verification code .
If the Chinese mobile number you linked to is deactivated by the end of 2025, then all the data on your cloud drive will instantly become a mirage that you can see but cannot touch.
The good news is that Quark actually left a backdoor—an account recovery channel.
Open the Quark App, click "My" → "Settings" → "Account and Security" → "Recover or Appeal Account" → "Account Recovery".
The first step is to select "Retrieve by mobile number" and enter the old, deactivated number.
The system will kindly ask if you are still using the number. Click "Discontinue use" and submit.
At this point, your Quark account avatar and nickname will pop up on the page. Click on them to continue to the next step.
Next, enter another Chinese mobile phone number you are currently using, check the box to agree to the agreement, and obtain the verification code.
After filling in the SMS verification code and clicking confirm, you will be taken to the "Third-Party Account Verification" step.
If you haven't linked your account to third-party login methods like WeChat or QQ, just click "Skip".
If you haven't activated your membership, select "No" for the "Member Order Verification" step.
The most challenging part is "Auxiliary Information Verification," which can be checked based on actual memory.
If you can't remember a few things, just choose one based on your intuition. If the system determines that most of the information is accurate, it will let you through.
According to the user who successfully recovered their cloud storage in 2026, the whole process was much easier than expected.
One mobile number can only be linked to one Quark account. This is an ironclad rule. Please think carefully before changing to a new number.
Why are Quark members suddenly restricted?
Many users think that canceling a phone number is just changing their contact method, but it's actually far more complicated than that.
If a mobile phone number is reclaimed and reissued by a mobile operator, the new owner can log in to your Quark account using an SMS verification code, which poses a risk of privacy file leakage.
Quark is a product of Alibaba and supports login via Alipay and mobile phone number. However, a Quark account is not the same as an Alibaba Cloud account. You do not need to go to the Alibaba Cloud account center to cancel your Quark account; you can apply for it within the Quark App.
The system will automatically verify the account status: if the account has incomplete orders or disputes, the cancellation application will be blocked; if the account has unexpired membership, cancellation can still be initiated, but once the cancellation is submitted, the remaining membership benefits will be directly invalidated.
The Alibaba ecosystem logic behind canceling a mobile phone number
Alibaba's cooling-off period, originally intended to give users a chance to change their minds, has become a double-edged sword.
Some Quark versions will have a 72-hour cooling-off period after confirmation of cancellation, during which the application can be cancelled at any time.
Other users have reported that Quark Drive offers a 14-day cooling-off period for account cancellations, during which users can log back in to retrieve their original account.
However, once the cooling-off period ends and the number is reclaimed by the operator, there is absolutely no way to log in again with the old number.
At this point, the only way is to use a new Chinese mobile phone number that you truly control to complete the second round of real-name authentication.
Step-by-step breakdown of the second real-name authentication activation process
The so-called "secondary real-name authentication" is essentially Quark requiring you to prove "I am me" again when your account is abnormal or changed.
The core of the activation process is to re-verify your account using a Chinese mobile phone number that you have complete control over, thus putting the security lock back in your own hands.
If you have a working private number, the entire activation process takes no more than three minutes.
After filling in the new number, receiving the verification code, and confirming, your membership privileges and original cloud drive data will be retained in their original positions.
The real challenge is dealing with old accounts where even the supporting information for the appeal is unclear; in those cases, the only recourse is to use the "account appeal" channel provided by customer service.
Account Appeal: The Last Channel for Old Accounts
Go to "Settings" → "Account and Security" → "More" in the upper right corner → "Account Appeal", submit your information and wait for review.
During the review process, you need to fill in information such as registration time, frequently logged-in city, and historical devices. The more specific the information, the easier it is to pass the review.
After the verification is approved, you will need to bind a new Chinese mobile phone number to complete the second real-name authentication loop.
Once this closed loop is closed, your Quark membership will return to "normal" from "restricted".
Imagine your Quark account as a precious treasure chest, filled with your life's moments and cherished memories. 📸🎁
A virtual phone number is like a key; only you know its secrets. No one else can open it! 🔑🚪
Furthermore, using a private, virtual Chinese mobile phone number to receive Quark SMS verification codes is like putting an invisible cloak on your account, protecting your privacy, enhancing the security of your Quark account, and effectively controlling spam interference, allowing you to roam freely and unrestrained in the world of Quark. 🧙️✈

publiccodeThe Real Cost of the Platform
When registering accounts for mobile apps, computer software , or websites, never use publicly shared online SMS verification code receiving platforms to avoid having your account stolen.
While publicly advertised SMS verification code platforms appear to be "technology businesses," they are in reality anonymous cover for fraud, order-brushing, and malicious registration.
A report by Legal Daily on January 12, 2026, clearly pointed out that "SMS verification code platforms" provide "anonymization" cover for various cybercrimes, and operators are often suspected of multiple criminal offenses such as infringing on citizens' personal information.
In January 2026, Qingdao police dismantled a criminal gang operating a "text message receiving platform," discovering that it had sold over 1 million text message data and illegally profited over 1 million yuan.
京山公安在2026年9月2日捣毁的「接码」窝点更触目惊心：现场查获已实名虚拟电话卡500张，截至案发共贩卖短信验证码数据25000余条。
The China Internet Joint Rumor Refutation Platform has issued a special notice regarding the risks of "SMS verification code groups," reminding the public not to register accounts using publicly available SMS verification code services.
Guangming.com reported a case where a telecommunications company deliveryman took advantage of his position to input the mobile phone numbers and verification codes of more than 60 customers into an illegal platform, earning nearly 1,000 yuan in just a few days. He was eventually brought to the attention of the police for infringing on citizens' personal information.
Yu Kui, a researcher at 360 Security, once publicly warned that the numbers provided in bulk by SMS verification code platforms are often accompanied by information leaks and black market chains.
The temporary number you buy for 1 to 10 yuan may have been used by someone else to register ten accounts just the day before—your Quark comes with a "dirty identity" from birth.
The best approach is to use a private virtual phone number, which is exclusively yours and cannot be accessed by others, thus eliminating the possibility of harassment and account theft at the source.
Add a lifetime insurance layer to your Quark account
Protecting an account is never a one-off action, but a long-term battle.
After a Chinese virtual mobile phone number is bound to Quark, when you change to a new phone to log in to your Quark account, you must use the bound Chinese virtual mobile phone number to log in, otherwise you will not be able to retrieve and log in to your Quark account.
Therefore, we recommend that you renew your private Chinese virtual mobile number regularly to improve the security of your Quark account.
If your phone number isn't renewed, it will be cancelled. You can only blame yourself for not renewing it on time.
You can use calendar software to set up automatic recurring reminders 3 days before the expiration date to prevent your number from being cancelled; it's very effective.
Once a phone number is cancelled, you can only register a new account; there's no way to recover it.
Instead of fantasizing about a reversal, it's better to accept reality and move forward.
Conclusion
In the information age, accounts are our physical bodies in the digital world, and mobile phone numbers are the lifeline that affects everything.
Preserving a Quark membership may seem like simply recovering a few gigabytes of data on your cloud drive, but at a deeper level, it means protecting the digital identity and trust assets you've built up over the years.
The ancient proverb "Be prepared for danger in times of peace" is particularly apt when applied to account security.
A true master never scrambles to prepare a treasure chest only when a crisis strikes; instead, they prepare the unique key while things are calm.
Take action now and lock your Quark account with a virtual phone number that's uniquely yours—let your freedom soar, starting with taking control of the key.
