How to get and activate a Singtel hi! (formerly Heya) eSIM in Singapore
Heya is now Singtel hi!, an eSIM-based service. Compare Singtel hi! eSIM plans, learn how to sign up, and see other eSIM options in Singapore.
Looking for a Heya eSIM? Here’s the short version: Heya itself never offered eSIM, and since December 2025 Heya has been rebranded into Singtel hi! — which sells all its plans as eSIM.
In this guide, we’ll cover Singtel hi!’s eSIM plans, how to sign up, and what other eSIM options you have in Singapore.
We’ll also explore other eSIM providers like Holafly’s unlimited eSIM, a seamless option for staying connected locally and abroad.
Get connected from anywhere
Buy your eSIM no matter where you are. All you need is an internet connection.
What is Singtel hi! (formerly Heya) eSIM?
Singtel hi! is Singtel’s no-contract digital mobile brand, and the successor to Heya — every Heya customer was automatically migrated to Singtel hi! starting December 1, 2025, with the same plan benefits.
Unlike Heya, which only ever supported physical SIM cards, Singtel hi! is built on eSIM: every plan on its official page is sold as an eSIM, managed through the Singtel hi! app,

Singtel hi! eSIM compatibility
Singtel hi!’s eSIMs work with eSIM-capable devices, including iOS, Android, and Google eSIM phones.
If you have doubts about whether your phone can use a Singtel hi! eSIM, check your device settings for an “Add eSIM” option before signing up. For an industry-wide comparison, check out our eSIM-compatible phones list.
How to buy a Singtel hi! eSIM?
To sign up for Singtel hi!, you need to:
- Be 16 years or older
- Have a Singpass account, or one of these ID documents: Singapore NRIC/11B, Employment Pass, S Pass, Work Permit, Dependent Pass, Student Pass, or Social Visit Pass
- Download the Singtel hi! app (available on the App Store and Google Play)
From there, choose a plan on the Singtel hi! site or in the app and select “Buy eSIM now.”
If you’re bringing your existing number, it must be an active non-Singtel postpaid line registered under your NRIC/FIN with no outstanding payments, and you’ll need to submit your port-out request to your current telco at least 7 days before your next billing cycle.
If you were on Heya, you didn’t need to do anything: the migration to Singtel hi! was automatic, your plan benefits carried over, and you kept your existing physical SIM. The Heya app has been retired — your account now lives in the Singtel hi! app.
Which telco also has eSIM in Singapore?
eSIM technology is now supported by most major telcos and MVNOs in Singapore, making it easier than ever to activate a mobile plan without a physical SIM card. Whether you’re after flexible contracts, budget-friendly data, or 5G support, there’s likely a digital SIM option to match your needs.
