Singapore, known for its cleanliness and modernity, enforces a ban on chewing gum, albeit sparingly. Often seen as a short-trip destination, it attracts visitors for shopping, dining, and exploring attractions. Despite being the most expensive country in Southeast Asia, using a local SIM card is recommended to save on expenses compared to international roaming.

Acquiring a SIM Card in Singapore for Individuals Aged 15 and Above

Individuals aged 15 or 16 and older, depending on the specific policies of mobile operators such as Singtel, StarHub, M1, and SIMBA (formerly TPG Mobile), are eligible to purchase a Singaporean SIM card. 

Notably, this option is available for both residents and visitors in Singapore. However, it is important to be aware of certain limitations. Specifically, there is a restriction that allows each individual to possess a maximum of three active SIM cards registered in their name in Singapore. Beyond this limitation, users have the freedom to utilise Singaporean SIM cards for their communication needs.

Options for Purchasing SIM Cards in Singapore

When looking to acquire a SIM card in Singapore, there are several convenient avenues available. Whether you are a resident or a visitor in Singapore, you can obtain a SIM card from any of these reputable providers. Typically, these SIM cards can be purchased at official stores, authorised resellers, or even online platforms. This accessibility ensures that individuals have diverse and convenient options when seeking to acquire a SIM card in Singapore to meet their communication needs.

Compatibility of Mobile Phones in Singapore

Ensure your mobile phone is GSM-compatible, as CDMA phones are not compatible with the technology used in Singapore. Most modern phones with a SIM card slot support GSM.

• Verify SIM Card Slot: Phones with a SIM card slot are likely compatible with Singapore's GSM technology. Confirm this feature, as it is common in approximately 99% of modern phones.

• Understand Frequency Bands: Recognize that Singapore operates on traditional European frequencies, falling within ITU Regions 1 and 3. Phones purchased in these regions should seamlessly function in Singapore.

• Consider Regional Differences: If your phone is from the Americas (ITU Region 2), check its specifications for compatibility. Low or medium-end phones without Tri-Band or Quad-Band support may have limitations, potentially restricting them to slower networks like 3G or 2G.

• Tri-Band or Quad-Band Support: For phones from the Americas, ensure compatibility by checking for Tri-Band or Quad-Band support. Medium/high-end devices with these features can be used in Singapore, including on advanced networks like 4G/LTE and 5G NR, to some extent.

• Network Speed Considerations: Be aware that lower-end phones may be restricted to slower networks, impacting data speed. Higher-end devices with advanced network support offer optimal connectivity in Singapore.

• Check for 4G/LTE and 5G NR Support: Verify if your phone supports 4G/LTE and, to some extent, 5G NR for enhanced network capabilities in Singapore.

Availability of VoLTE and VoWiFi Services in Singapore

In Singapore, both VoLTE (Voice over LTE or HD Voice) and VoWiFi (Voice over WiFi or WiFi calling) services are accessible, although not all mobile operators provide both options. 

The significance of this is that users can make calls without the need for their phones to revert to 2G or 3G networks, a convenience not offered by operators lacking VoLTE support.

The following mobile operators in Singapore offer both VoLTE and VoWiFi services:

5G NR Deployment in Singapore

Since September 2020, Singapore has introduced commercial 5G NR connectivity, accessible through Singtel, StarHub, M1, and SIMBA (formerly TPG Mobile) networks. Notably, Singtel is the sole provider permitting prepaid customers to access 5G NR, contingent on the purchase of a specific 50 SGD plan. 

In contrast, other network operators do not extend this privilege to prepaid users. This signifies a significant advancement in telecommunications technology, bringing the benefits of 5G NR to users on selected plans in Singapore.
