Accessing reliable mobile service in Singapore is straightforward, but it helps to know your options before arriving. The country has strong network coverage and several telecom providers offering prepaid SIM cards and eSIM plans made for short-term visitors. Setting up mobile data in advance allows you to stay connected for navigation, messaging, and online bookings without depending on public Wi-Fi or paying roaming fees. Understanding how local SIM cards and eSIMs work will help you choose the option that fits your travel plans best.

Singapore Travel SIM Cards

Singapore travel SIM cards are designed for short-term visitors and provide affordable access to mobile data, local calls, and messaging. They can be purchased at Changi Airport, mobile operator stores, and selected retail outlets, or ordered online before arrival. Most cards come with a fixed amount of data and a defined validity period.

Typical features include:

• Data-focused plans, with optional call and SMS allowances.

• Validity ranging from 7 to 30 days depending on the provider.

• Quick activation after registration with a passport or travel document, as required by local regulations.

• English-language assistance at airport counters and main city branches.

When selecting a SIM card in Singapore, consider how long you will stay, how much data you expect to use, and whether you need local or international calls. Tourist packages often include large data allowances, such as 100 GB for 14 days or 120 GB for 28 days, depending on the operator.

Remember to check your device’s compatibility with Singapore’s mobile networks. Common 4G LTE bands are B3 (1800 MHz), B7 (2600 MHz), B8 (900 MHz), and B38 (TDD 2600 MHz), while 5G networks mainly use n1 (2100 MHz), n78 (3500 MHz), and n28 (700 MHz). Ensuring your phone supports these bands will help maintain reliable coverage throughout Singapore. [1]

They are available at Changi Airport, in official mobile operator stores, electronics retailers, convenience stores like 7-Eleven, and occasionally through trusted online sellers. These physical SIM cards generally include mobile data, local call minutes, and SMS. Some plans also provide limited international calling or roaming features, depending on the provider. A passport is required at the time of purchase for registration, as mandated by Singapore’s telecom regulations, but a local address is not necessary. Plans usually have a validity period between 7 and 30 days, with data allowances ranging from small packages for casual use to large plans offering over 100 GB for heavier data needs.

Visitors staying longer can choose 28- or 30-day plans with more data and sometimes local calls or SMS. A few plans also include limited international minutes or regional roaming.

When choosing a plan, think about how much data you will need and where Wi-Fi is available, as free internet is common in hotels, malls, and public places.
