Nowadays, almost everyone owns a communication SIM card. However, due to certain reasons, some SIM cards may be locked in both directions. So, what should you do when your SIM card is locked in both directions, can it be restored or do you have to replace it with a new one? The following content will help you answer this question.

What does it mean when a SIM card is locked in both directions?

When a SIM card is locked in both directions, it means that the telecommunications network locks the SIM card in both the outgoing and incoming directions. In that case, users cannot use the SIM card to make any calls or send any messages. At the same time, calls and messages to your mobile phone cannot be received either.

It is very simple to identify the information of a subscription that is locked in both directions. When entering *101# to check information and balance in the SIM card, you will receive the message “Subscription has been locked in both directions.” Or when you insert the SIM card into a mobile phone or tablet that supports SIM cards, there will be no signal or the signal bar will have a red X mark.

Reasons for a SIM card being locked in both directions

There are many reasons that can lead to a SIM card being locked in both directions. Some common reasons include:

  • Expired SIM card: For prepaid SIM cards, if you do not use the SIM card for a long time or do not top up the balance, it will be locked in one direction. If you still don’t top up within the specified time, the subscription will be locked in both directions.
  • Failure to pay the bill: For postpaid SIM cards, if you fail to pay the bill on time, the network will lock it in one direction. If you continue to not pay within the specified time, the network will lock it in both directions.
  • Unregistered SIM card: According to the regulations of the State and current networks, any SIM card that has not provided the owner’s information for a mobile subscription is considered unregistered.
  • Incorrectly entering the recharge code more than 5 times: When topping up with a scratch card and entering the wrong code more than 5 times, the SIM card will be locked in both directions.
  • Wrong PUK code: To secure SIM card information, many users have set a PUK code. However, if the wrong code is entered more than 3 times, the SIM card will be locked in both directions.
  • Reported as spam: If you use the SIM card to send spam, advertisements, and are reported by multiple users, the network will categorize your SIM card as spam and block it in both directions.
