The Momo e-wallet is widely trusted for its convenience. To own 'a wallet,' you need to use a SIM registered under your name. If your phone number is already linked to an account, you can delete the old account information and re-register. Below, Mytour will guide you on how to handle this situation.

I. Why Is a Newly Purchased SIM Already Registered with Momo?
In reality, there's no need to worry too much if you receive a notification that your SIM is already registered with Momo. This could be because the previous owner registered it, and when the SIM expired, the information on Momo was retained. You just need to perform a few simple steps to update the information to your own.
Alternatively, the second scenario could be due to accidentally exposing your personal information, allowing someone else to use your number to register for Momo. To prevent this, make sure to review your security settings.

II. Are There Any Issues with Using a SIM Already Registered with Momo?
If you use a phone number already registered with Momo, you might face issues if the previous user had loan transactions or unpaid debts on the wallet. Debt collectors might bother you with calls, or the previous owner might repeatedly request OTP codes.
Another inconvenience is that while using the wallet, you might frequently face facial recognition checks by the Momo app. If the app detects a mismatch with the registered information, your Momo wallet's credibility score could drop, making it harder to use. Therefore, it's best to delete the old information and re-register the Momo wallet with your own phone number and personal details.
III. How to Resolve This Issue?
To recover your Momo account linked to your phone number, first ensure that the SIM you are using is registered under your name. If the SIM still carries the previous owner's information, visit the service centers of network providers like Vinaphone, Mobifone, or Viettel to re-register it under your name.
The process of registering a SIM under your name typically requires you to provide your ID card (CMND/CCCD) and the five most recent contact numbers. Make sure to prepare these documents in advance.
If the SIM is already registered under your name, but the Momo account was registered by someone else, you should proceed to delete the Momo wallet and then register a new one. Detailed steps will be provided below:
