Why Buy a Local SIM Card?

Purchasing a local prepaid SIM card in Singapore is highly recommended to avoid costly roaming charges. Singapore has excellent 4G LTE coverage, so a local SIM will provide fast and reliable connectivity across the city. With a prepaid SIM, you only pay for what you use, without any contracts.

Beyond avoiding roaming fees, a local SIM card also allows you to:

  • Make affordable local calls and texts
  • Use data/internet anywhere in Singapore with a local data plan
  • Access apps, maps, and web services using a Singapore phone number
  • Stay connected with people you meet in Singapore via call/text

When Should You Buy Your SIM Card?

It’s best to purchase your prepaid SIM card as soon as you arrive in Singapore. SIM cards can be purchased at Changi Airport as well as many convenience stores and phone shops across the city.

Buying your card early allows you to insert the SIM and test that it is working properly during your trip. Purchasing a SIM card upon arrival also means you can use it for essential tasks like contacting your accommodation, accessing maps or ride services, and more.

If you wait too long to buy a SIM card, you may find yourself stuck without connectivity when you really need it.

Where To Buy a SIM Card in Singapore

Prepaid SIM cards can be purchased at many locations across Singapore, including:

  • Changi Airport – All major providers like Singtel and StarHub have desks at arrival halls in the airport terminals. This is the most convenient option if you want a SIM right upon arrival.
  • Convenience stores – Major chains like 7-Eleven and Cheers sell prepaid SIM cards over the counter.
  • Phone retailers – Stores like Singtel Shop, M1 Shop, and StarHub Shop offer a wide range of SIM cards. Sales assistants can also help you choose the right plan.
  • Online – Some providers may allow online purchase and delivery of SIM cards before arrival. However, airport or in-store pickup is more common.

When purchasing at Changi Airport or popular tourist areas like Orchard Road, be prepared for slightly higher prices than at local stores. However, the convenience may be worth it.

Choosing the Right SIM Card Provider

There are three major telecommunication providers in Singapore that offer prepaid SIM cards:

  • Singtel – The largest telco in Singapore with the widest coverage. Its GOMO prepaid SIM offers good value for tourists.
  • StarHub – Second largest provider, on par with Singtel for coverage. Its Happy Prepaid SIM is popular with visitors.
  • M1 – The newest telco with growing coverage. Its MiFi prepaid SIM is also reliable for tourists.

A few key factors to consider when choosing a prepaid SIM provider:

  • Coverage – Singtel generally has the widest 4G coverage, followed closely by StarHub. M1 reaches most areas but has some gaps.
  • Data plans – Compare data allotments. Most tourist SIMs come with 1-3GB lasting 5-15 days. Some offer unlimited data.
  • Prices – Singtel, StarHub, and M1 have comparable rates. Under S$20 can get you a SIM with a few GB of data.
  • Validity – Many SIMs expire after a set number of days. Opt for longer validity like 15 or 30 days if staying longer.
  • Convenience – Choose providers with easy top-up options and availability at key pickup points like the airport. You can visit for the best plans and reliable prepaid sim cards.

For short 1-2 week trips, the major providers are all solid options with similar offerings. Compare rates and data amounts to choose what fits your needs.
