Updated: 16 February 2026 
By Hannah Geremia, Digital Content Editor of WhistleOut Singapore. 

What are the different types of SIM-only plans?


With SIM-only plans in Singapore, you'll pay for a SIM with service from your telco of choice. You'll bring a phone, whether that's brand new or one you already own. SIM-only plans come in two types: prepaid and postpaid plans. The main difference between prepaid vs postpaid plans in Singapore is when you pay.


Prepaid SIM-only plans

With a prepaid SIM-only mobile plan you pay upfront for your plan.

  • These plans come in different expiry amounts. The most common is a 28 or 30-day expiry
  • When your plan expires, you forfeit any remaining data, SMSes, or call minutes. Many telcos offer data rollover, though, so you can keep using your data come the next cycle.


Postpaid SIM-only plans

Postpaid SIM-only plans are paid for after the fact.

  • These plans are billed month to month (sometimes on a contract)
  • Sometimes you'll get extra perks, like a streaming service subscription or roaming data
  • If you exceed your monthly data, SMS, or call allowance, some providers may hit you with additional fees
  • Some telcos offer unlimited data (more on that below)


Some commonly seen features you'll get with SIM-only plans include:


Data rollover
Also called data banking, it's useful on prepaid plans. You can roll over any data you don't use to the next month


Unlimited data
Forget worrying about running out of data or being charged excess data fees. Capped speeds after you use your data allowance


International Direct Dial (IDD) add-ons
Some providers include IDD minutes in plans so you can make calls overseas


Data roaming
Data roaming add-ons are a cheaper and sometimes easier alternative to IDD


5G connectivity 
Most providers offer 5G now although the networks are still in the process of being rolled out

Which providers offer SIM-only plans in Singapore?


Big telcos like StarHub and Singtel aren't the only ones who offer SIM-only mobile plans in Singapore. There are also many smaller providers to choose from, otherwise known as Mobile Virtual Network Operators (MVNOs). The same mobile networks that power StarHub, Singtel, and M1 also power their MVNOs. 

Typically, because they don't have to pay the overheads to maintain the network, MVNOs have simpler products and cheaper prices. 

StarHub SIM-only plans

As a StarHub customer, you’ll have access to SIM-only mobile plans for BYO devices or as part of postpaid bundles. StarHub also caters to prepaid mobile users and those who need broadband home internet. When it comes to SIM-only plans. When it comes to SIM-Only plans, each plan includes:

  • Roaming data
  • Free incoming calls and SMSes
  • Contract free options

Things that you need to watch out for with SIM-only plans


There are a few things to be on the lookout for when choosing between SIM-only plans:

  • Most inclusions are for use within Singapore only - However, the majority of plans include some roaming data for nearby countries (or even global roaming if you're lucky). 
  • Most plans don't include international talk, text and MMS - However, there are a handful of providers that offer add-ons for talk and text while travelling abroad, as well as IDD minutes that allow you to call other countries from Singapore.

Is it better to buy a phone outright and get a SIM-only plan?


These mobile plans end up being cheaper than regular plans because you don't have to pay for a new phone. They have the same bells and whistles as regular plans.

This kind of mobile plan might be right for you if:

  • You're looking to save on your monthly phone bill
  • You already have a phone that you want to keep
  • Your contract is ending, but you're waiting for a new phone release to upgrade. 

It might not be the best option for you if:

  • You can't afford to buy the phone you want outright
  • You want to take advantage of the perks you get when buying a new device

Cheap SIM-only plans in Singapore


It's not uncommon to pay up to $100 per month for a phone on a plan these days. You can save a lot of money by using an existing phone instead of forking out for the latest iPhone and pairing it with a cheap SIM-only mobile plan.

SIM-only plans FAQs


What is a SIM card?

A SIM (Subscriber Identity Module) card is a tiny removable card that stores data needed to identify a subscriber on a mobile network. You can remove your SIM from your current phone and insert it into any other compatible device. You've also got the option of an eSIM, or electronic SIM card.

How do you switch SIM-only plans?

Switching to a new mobile plan is as simple as finding one you like and signing up. As part of the process, you can even decide if you want to "port" your number so you can keep your existing phone number. Transferring your number can take no time at all or up to a few days, depending on the telco. Your new provider will have information about the time it takes to process transfers.

As soon as your new plan is activated, you're good to go. If you’re not porting your number, you’ll need to contact your old provider and cancel your service.  

Can I keep my mobile number when I switch mobile plans?

Yes, during the switching process, you have the chance to port your number to your new mobile plan provider.

Can I choose my mobile number when signing up for a SIM-only mobile plan?

Yes, a handful of telcos let you choose your mobile number. This includes Circles.Life, M1, giga, redONE, Singtel, SIMBA, StarHub, MyRepublic, Changi Mobile, VIVIFI, GOMO, and eight. 

Can I get a 5G SIM-only mobile plan in Singapore?

Yes, select phone plans include 5G network access.
