Getting connected is one of the first things you will want to do after landing, because almost everything else in Singapore, from Singpass to food delivery to your bank’s one-time passwords, depends on a working local number. This mobile broadband newcomer Singapore guide walks you through getting a SIM card at the airport, choosing between prepaid and postpaid, and setting up home fibre so your flat is online within days rather than weeks. The good news is that Singapore is one of the most connected places on earth, and the process is far simpler than the paperwork you may be used to back home.
Getting a Local SIM Card First
Your very first priority is a Singapore mobile number. You can buy a prepaid SIM the moment you arrive, and many newcomers pick one up at the airport before they even reach the taxi queue. Convenience stores, telco shops in the malls, and even some supermarkets sell prepaid SIM cards over the counter.
To buy any SIM in Singapore you must show your passport, because all numbers are registered to an identity document under local regulations. If you have your Employment Pass, S Pass, Student Pass, or Dependant Pass card already, bring that too, as some postpaid plans want to see it. A single passport can usually register only a limited number of prepaid lines, so keep that in mind if your whole family is setting up at once.
Many phones sold today support eSIM, a digital SIM you activate by scanning a QR code rather than inserting a physical card. This can be a fast way to get a second line or to keep your China number active on one slot while running a Singapore number on another. Check that your handset supports dual SIM or eSIM before you rely on this.
A quick word on your China number: you do not have to give it up. Keeping it active for banking verification and family contact is common, and we cover the trade-offs separately. See keeping a China phone number in Singapore for the details.
Prepaid Versus Postpaid Plans
The main choice for your mobile line is between prepaid and postpaid. Prepaid means you top up a set amount and use it until it runs out, with no contract and no credit check. Postpaid means a monthly plan billed to you, usually with more generous data and extras, but it often asks for local employment or residency documents and sometimes a deposit for newer arrivals.
For your first weeks, prepaid is usually the sensible starting point. It gets you connected immediately with just a passport, and you can switch to postpaid later once your pass is issued and you have a local address and bank account. Many people run prepaid for a month or two, then move to a postpaid or SIM-only plan when their life here is more settled.
Here is how the two compare for a typical newcomer:
| Factor | Prepaid SIM | Postpaid plan |
|---|---|---|
| Documents needed | Passport only | Passport plus pass and often proof of address |
| Contract | None, pay as you go | Often a fixed term, or a no-contract SIM-only option |
| Best for | First days, short stays, backup line | Settled residents wanting more data and extras |
| Billing | Top up in advance | Monthly bill, usually to a local account or card |
| Switching away | Just stop topping up | May involve notice or early-termination terms |
Singapore has several major telcos plus a number of smaller providers that run on the same networks, so you will see a wide range of plans. Rather than quote prices that change often, compare current offers on each provider’s website and look at the data allowance, roaming to China, and any contract length before you commit.
Choosing a Home Broadband Connection
Once you have a home address, home broadband is the next step. Almost all residential broadband in Singapore runs over fibre, delivered through the nationwide fibre network that reaches virtually every HDB flat and condominium. This means fast, stable connections are the norm rather than the exception.
Setting up home fibre usually involves three parts:
- A fibre termination point in your flat, which most homes already have installed. If yours does not, the provider arranges for it to be fitted.
- A plan from an internet service provider, which you sign up for online or in a shop.
- A router, often included with your plan, plus an ONT box that connects your home to the fibre.
If your unit already has an active termination point, activation can be quick. If a technician needs to visit to install or check the point, book the appointment early, because slots can fill up during busy moving periods. When you rent a flat, ask your landlord or agent whether broadband is already wired and active, as some units come ready to go.
Documents, Deposits, and Practical Tips
Newcomers sometimes hit small snags because a service wants a document they do not have yet. Keeping the following ready will smooth things along:
- Your passport, always, for any SIM registration.
- Your pass card (Employment Pass, S Pass, Student Pass, Dependant Pass, or your PR or long-term visit pass) once issued.
- Proof of local address, such as a tenancy agreement, for postpaid mobile and home broadband.
- A local bank account or a card that works here, for monthly billing. Until that is set up, prepaid keeps you covered.
Do not sign a long broadband contract before you are sure of your address, because moving mid-contract can be a hassle. If you expect to relocate within Singapore soon, ask about the provider’s relocation policy or choose a shorter commitment. Newer residents are sometimes asked for a deposit on postpaid services, which is normal and usually refundable under the provider’s terms.
Finally, set up your connectivity in an order that unblocks everything else: prepaid SIM first, then use that number to register Singpass and your banking, then arrange home fibre once your address is confirmed. That sequence saves a lot of circular waiting.
This is general information to help you get connected, not personalised financial, legal, or telecommunications advice. Plans, promotions, and registration rules change on the Singapore side, and mobile and forex rules can change on the China side too, so verify current mobile and broadband terms directly with the telco or internet provider, and confirm any China number or roaming questions with your Chinese carrier or the Chinese Embassy or Consulate in Singapore where relevant. Rules on both sides change, so always check the latest requirements before you commit.
