FAQs about How to Use Your Phone in Singapore
Your phone can indeed function in Singapore, but the costs you’ll face and the choices available to you will vary depending on a few important factors.
In this guide, we’ll walk you through everything—from checking whether your device is locked to a carrier to exploring the best ways to stay online while overseas. We’ll also explain how using an international eSIM can help travelers cut expenses and enjoy a stable internet connection during their trip.
Will my phone work in Singapore?
Most likely yes, but a few checks are necessary first. Singapore operates on GSM networks, with 4G LTE widely available across the country and 5G services gradually expanding. Before traveling, it’s important to check your phone’s frequency bands to ensure compatibility.
To use a local SIM card or eSIM card, your device must be unlocked, as carrier-locked phones may not function with Singaporean networks. Additionally, Singapore uses Type G power plugs with a 230V electrical standard, so make sure to bring the right charger or adapter for your devices.
Do I need an international plan for Singapore?
Whether you need an international plan for Singapore largely depends on your travel style, budget, and how much data you expect to use. For many travelers, sticking with their home carrier’s roaming service is the simplest option — but it’s also often the most expensive.
If you’re in Singapore for just a few days, roaming with your home carrier or using a daily pass may work. However, for longer stays, a local SIM card or local eSIM is far more affordable and offers generous data packages from providers like Singtel, StarHub, and M1.
Another option is to choose a regional eSIM plan, which is ideal for travelers visiting multiple countries in Asia. This allows you to stay connected without buying a new SIM in every destination.
Mobile internet options in Singapore
If your phone supports Singapore’s frequency bands and isn’t locked to a carrier, you have four main ways to stay connected while traveling. Here’s a breakdown of each option, what it offers, and the potential costs.
ByteSIM Singapore eSIM
For travelers with eSIM-compatible devices, using an eSIM is often the easiest choice. Activation takes just seconds, and many plans offer unlimited data.
The ByteSIM Singapore eSIM, for example, works for up to 30 days and includes unlimited data. Connect on StarHub 5G for the fastest downloads, ByteSIM offers strong 5G uploads, and island-wide reliability.
It also provides unlimited hotspot usage (depends on your plan allowance), 24/7 customer support, high-speed 5G connectivity, and a quick setup process for both Android and iOS devices.

Local SIM cards for Singapore
If your phone is unlocked, you can easily pick up a prepaid SIM card from any major mobile operator in Singapore. Keep in mind that you’ll need to present a valid passport and often a credit card to complete the registration under your name. You may have to wait in long queues at the airport or search for a shop.
Roaming from your local carriers
Roaming in Singapore is one of the most straightforward ways to stay connected for internet, calls, and texts while traveling. However, this convenience often comes at a higher cost compared to local SIM cards or eSIM options. To give you a clearer idea, here’s a breakdown of what some major Australian and US carriers charge for roaming in Singapore:
Pocket WiFi in Singapore
Traveling with a pocket WiFi for Singapore is an ideal solution to share data with other devices. However, a daily plan can cost you up to $49.90/day, which is often more expensive than using international roaming. Plus, this pricing usually doesn’t include additional charges, such as delivery fees, airport pickup, or add-ons like portable chargers.
