Singtel roaming allows you to stay connected while travelling overseas using your existing Singapore mobile number. There is no need to change SIM cards, as your Singtel line connects to partner networks abroad for calls, SMS and mobile data.
As Singapore’s largest telecom provider, Singtel offers international roaming plans with wide global coverage. Depending on your subscription, you can choose from data roaming passes, regional bundles, or pay as you go roaming rates.
In this guide, you will find everything you need to know about Singtel international roaming, including supported countries, roaming charges, available plan types, and how to activate Singtel roaming before your trip. We also explain how to avoid unexpected roaming fees and when a prepaid travel eSIM such as TurkSIM may offer better value for data abroad.
Singtel roaming is an international roaming service that allows you to use your Singapore mobile number, calls, SMS and mobile data while travelling overseas. Instead of purchasing a local SIM card, your Singtel SIM connects to partner networks abroad, and any roaming charges are billed to your existing account.
Singtel currently supports roaming in more than 137 destinations for voice services, with broader international data roaming coverage depending on your plan type. Availability, roaming rates and data options vary significantly between postpaid and prepaid plans, so it is important to check your specific subscription before travelling.
Singtel offers two main types of roaming setups depending on your account type. Postpaid users have access to the full range of roaming bundles, while prepaid users are limited to one-time data packs via the hi!App.
Important for prepaid users: Roam Asia and Roam Worldwide bundles are not available to Singtel prepaid customers. Prepaid users must purchase one-time data packs through the hi!App or use pay-as-you-roam rates, which can be significantly more expensive per MB.
Singtel roaming pricing varies by destination zone and plan type. Here's an overview of current options based on publicly available plan information:
Note: From 28 October 2024, all Singtel packs activate immediately upon purchase. To get the most out of your validity period, buy the plan after arriving at your destination — not before.
Coverage depends on which plan you're on. Postpaid customers on the Roam Asia bundle can access 18 countries including Malaysia, Thailand, Japan, South Korea, and Australia. The Roam Worldwide bundle extends this to 81 destinations across Europe, the Americas, and beyond.
There are some known coverage gaps worth noting:
If you're heading to any destination outside the 81-country Worldwide bundle — or if you're a prepaid user — your options become much more limited.
Activating Singtel roaming is straightforward for postpaid users:
Prepaid users on the hi!Plan can access roaming packs through the hi!App. Some postpaid plans are also available via the Singtel website chatbot or by calling the customer hotline.
Even with a roaming plan active, data costs can add up faster than expected. These habits help keep your bill under control:
Singtel roaming is convenient if you need to keep your Singapore number active — for banking OTPs, WhatsApp verification, or staying reachable on your local number. But for travellers who primarily need data, a dedicated travel eSIM often makes more financial sense.
Consider a travel eSIM if:
A TurkSIM eSIM installs digitally — no physical card, no queuing at the airport. You keep your Singtel SIM active for calls and SMS, while the eSIM handles your data at local rates. Most modern smartphones support dual SIM (physical + eSIM) simultaneously.
Singtel supports voice roaming in over 137 destinations and data roaming in up to 81 countries under the Worldwide bundle. Some locations — including Jammu & Kashmir and Myanmar — are currently excluded from data roaming. Always check Singtel's roaming guide for your specific destination before travelling.
Yes, but with more limited options. Prepaid users on Singtel's hi!Plan can purchase hi!DataRoam packs via the hi!App for certain Asian destinations. The main Roam Asia and Roam Worldwide bundles are only available to postpaid customers.
Since October 2024, all Singtel packs activate immediately upon purchase. To get the most out of your validity period, it's best to buy the plan after you've arrived at your destination rather than before departure.
If you exhaust your ReadyRoam data allowance, Singtel automatically adds another block of the same plan at the same price. The validity period does not extend — only the data is topped up. This can catch travellers off guard, so monitoring usage in the My Singtel app is strongly recommended.
Yes. Most modern smartphones support dual SIM (physical SIM + eSIM). You can keep your Singtel SIM active for your Singapore number while using a TurkSIM eSIM for data — this way you stay reachable on your local number without paying Singtel roaming data rates.
Singtel's 5G+ Priority and 5G+ Enhanced plans include built-in roaming benefits across up to 81 destinations. However, 5G speeds abroad depend on whether the local partner network supports 5G roaming — in many destinations, you'll be connected on 4G/LTE.
