📱 How Many Prepaid SIM Cards Can You Own in Singapore?

As of 2025, each individual can register up to three (3) prepaid SIM cards in Singapore, regardless of the telecom provider. This rule applies to both locals and foreigners.

Key Points:

• You can only register 3 prepaid SIMs per person.

• This includes physical SIMs and eSIMs.

• Applies to tourists, foreign workers, and residents alike.

• Registration requires valid identification (e.g., passport, NRIC, FIN).

If you've already registered 3 prepaid SIMs, you won’t be able to activate a new one unless you cancel an existing line.

📶 What About Postpaid SIM Cards?

Unlike prepaid SIMs, postpaid mobile plans are not restricted by the same three-card rule. However, telecom companies may still perform internal checks or set limits based on:

• Credit score

• Billing history

• Identity verification

If you're planning to own multiple postpaid lines (e.g., for business or family use), it's best to discuss directly with your provider.

Visiting Singapore and planning to buy a tourist SIM card? You're still subject to the 3 SIM card rule. If you've previously bought tourist SIMs under your passport, the system will count those too.

Most tourist SIMs offer:

⚖️ Why Is There a Limit on SIM Cards in Singapore?

Singapore’s strict SIM card policy was introduced to:

• Prevent scam calls and fraud

• Combat illegal activities (e.g., SIM box operations, spoofing)

• Enhance mobile security for all users

By linking every SIM to an official ID, the government can track and verify mobile activity when necessary.
