View Mobile Planhi! is Singtel's own prepaid brand — contract-free mobile plans running directly on the Singtel network, with 5G+ available on eligible plans. It's been Singapore's best-known prepaid name for decades, sold everywhere from convenience stores to the airport, and now runs largely through the Singtel Prepaid hi!App.
The lineup covers all-in-one prepaid plans on 30-day cycles, a dedicated plan for seniors aged 60 and above, and tourist SIMs and eSIMs with APAC roaming for visitors. Plans bundle local data, calls and SMS, with add-ons for roaming data and IDD minutes when you travel or call overseas. A standout perk is data rollover: top up before your plan expires and unused data, calls and SMS carry forward, stacking for up to six months.

Why choose Hi! by Singtel?
hi! pairs prepaid flexibility with the network prepaid users rarely get: Singtel's, including 5G+ on eligible plans. There's no contract and no credit check — buy a SIM or eSIM, activate in the hi!App, and top up only when you need to, with rollover protecting whatever you don't use.
It's also one of the most accessible brands in Singapore: SIMs are sold online and at authorised retailers island-wide, the app handles everything from activation to eSIM replacement, and there's a dedicated plan for seniors plus tourist options for short-term visitors. For anyone who wants big-telco coverage without a monthly bill, hi! is the default choice.
Frequently asked questions
What is hi! by Singtel?+
hi! is Singtel's prepaid mobile brand — often searched as "hi mobile". It offers no-contract prepaid plans (data, calls and SMS on 30-day cycles), tourist SIMs and a seniors plan, all managed through the Singtel Prepaid hi!App. Because it's Singtel's own brand rather than a reseller, you're on Singtel's network end to end.
Which network does hi! use? Is it really Singtel?+
Yes — hi! runs directly on the Singtel network, with 5G+ available on eligible plans. Coverage, speed and reliability are the same as for Singtel postpaid customers; only the payment model (prepaid, no contract) differs.
How do I top up my hi! prepaid plan?+
The easiest way is the Singtel Prepaid hi!App (iOS and Android), where you can top up, buy data, IDD and roaming plans, and track your balance and validity — or visit any authorised retailer to top up in person. See the official hi! page for channels. Top up before your plan expires to keep your rollover benefits.
Does hi! by Singtel support eSIM?+
Yes — hi! supports eSIM for both local prepaid and tourist plans. You can activate an eSIM via the hi!App, switch a physical SIM to eSIM, or request a replacement in-app (Me → Request New SIM). Compare other eSIM plans in Singapore to see the full field.
Does hi! prepaid have 5G?+
Yes — eligible hi! prepaid plans include access to Singtel 5G+, so with a 5G-capable phone you get the same next-gen network as postpaid users, without a contract. Check the plan cards above for current 5G options, or compare all 5G plans in Singapore.
Does hi! have a plan for seniors?+
Yes — hi! offers a dedicated prepaid plan for seniors aged 60 and above, with a simple 30-day bundle of data, calls and SMS. See its live price on the cards above, and compare it with other senior citizen mobile plans before deciding.
Does unused hi! data roll over?+
Yes — if you top up your hi! plan before it expires, unused local data, roaming data, calls and SMS are automatically rolled over and can stack for up to 6 months. It's one of the most generous rollover policies of any Singapore prepaid brand.
