Looking for an affordable mobile plan in Singapore without a long-term commitment? Start by deciding whether you prefer to pay upfront with a prepaid SIM or use a no-contract plan with recurring payments. Prepaid gives you control over when you top up, while a no-contract recurring plan can be more convenient if you want to avoid manual top-ups. Prepaid plans can also be no-contract; the key comparison here is manual top-ups versus recurring payments.
hi! by Singtel offers both prepaid services and no-contract mobile options. Depending on the plan, you can also get generous local data and benefits such as Singtel 5G+, roaming, international calls and rollover. Here’s how to choose based on the way you use your phone.
What is the difference between prepaid and no-contract mobile plans?
With a prepaid mobile plan, you pay in advance and top up your service as needed. This may suit you if you prefer to manage spending directly or want flexibility over when to add value. Some prepaid plans also offer automatic top-ups.
With a recurring mobile plan, payments are made regularly instead of through manual top-ups. A recurring plan does not necessarily mean a long-term contract: hi! also offers no-contract options with payments every 30 days.
Choose prepaid if paying upfront and managing top-ups matter most. Consider a no-contract recurring option if you prefer automatic payments without a lengthy commitment. In either case, compare the actual inclusions, not just the plan label.
How do you choose a mobile plan with enough data?
Start with how you use your phone: messaging and maps generally require less data than frequent video streaming or hotspot use. Check the local data allowance, its validity period and what happens when you run out. If you regularly use up your allowance early, consider a plan with more data.
hi! offers mobile options with generous local data. The amount included depends on the plan you select, so compare the latest hi! mobile plans and data allowances before signing up.
Can a prepaid SIM in Singapore include 5G?
Yes. Selected hi! plans include access to Singtel 5G+ when used with a compatible device in an area with 5G coverage. Check the specific plan’s network access and device requirements rather than assuming 5G is only available with traditional postpaid plans.
Can you use a Singapore prepaid SIM overseas, including in Malaysia?
Yes, selected hi! plans include roaming data for eligible destinations. If Malaysia is covered by your plan, you may be able to use your Singapore SIM for maps, messaging and ride-hailing on trips to Johor Bahru, without relying on a separate travel SIM.
Before travelling, confirm the destination is covered, how much roaming data is included and how long the allowance is valid. Roaming destinations and allowances vary by plan. Check hi! roaming destinations and setup guidance before your trip.
What happens when your prepaid data runs out?
Check your remaining balance and the top-up or plan options available for your current hi! service through the hi! app. Because prepaid is paid upfront, you can decide when to add more value. If you frequently run out of data, compare plans with larger allowances. For help, see Singtel prepaid balance and top-up support.
Can unused mobile data roll over?
On selected hi! plans, eligible unused data, roaming and IDD benefits can roll over for up to six months, when you top up before your current plan expires, subject to plan terms. Check which benefits qualify and their validity when comparing plans; rollover is not available on every option.
What if you make international calls regularly?
If you call family, friends or contacts overseas, look beyond local data. Selected hi! plans include international direct dialling (IDD) benefits for eligible international destinations. Compare the countries covered, included calling minutes and applicable terms.
Which hi! mobile option is right for you?
If you want to pay upfront and choose when to top up, explore hi! prepaid options. If you prefer recurring payments without a long-term commitment, consider a hi! no-contract mobile option. For travel, international calls or 5G+, check the specific benefits included rather than assuming every plan offers the same features. Check cancellation notice periods and any early termination or port-out fees in the hi! plan terms.
