Prepaid SIM cards vs postpaid SIM cards

With a prepaid SIM card plan, you're not locked in with a provider for an extended period. You can switch providers without incurring hefty termination fees, which is something most postpaid mobile users don’t have access to.

Your rates will also be much cheaper when compared to postpaid options. And if you run out of data, it’s straightforward to purchase another package to access more.

What frequencies are used in Singapore?

It is important to remember that Singapore uses the 3500 band for 5G; 900, 1800, 2600, TDD 2300, TDD 2600 for 4G, and 900 and 2100 bands for 3G, which are more common in Asian/European countries.

If you’re coming from other countries, it’s best to check if your phone is compatible with these bands, or if you’ll need to purchase a phone in Singapore.

SIM card prices in Singapore, and where to buy them 

You can get a local SIM card for S$5 up to S$60. There are different types of prepaid SIM cards available with prices that range widely, but all are pretty affordable.

You can find prepaid SIM cards for tourists at the Changi Recommends booths at Changi Airport, or convenience stores such as Cheers and 7-Eleven.

Prepaid data plans for travellers

International roaming charges are high, so buying a prepaid SIM card while you're in Singapore is important. If this is your first time buying one from abroad, just know that there can be different types of plans and prices depending on what they offer.

Best data plans for short-term tourists

Short-term tourist SIM cards work best for those who only visit Singapore for 7 days. The three largest telcos offer 100 GB of data, 500 minutes of local outgoing calls, and 100 SMSes per month with 1 GB of roaming (for Singtel and StarHub only; no roaming data is offered for M1's 7 Day Prepaid Tourist SIM Card).

The benefit of this type of card is that it allows you more freedom when travelling without any additional commitments after your stay in Singapore ends.
