What is a SIM-Only Plan?

Thinking about getting the best SIM-only plan for your phone? SIM-only plans with low cost monthly subscriptions in Singapore enable you to pay purely for the mobile services you use, such as data, calls, and texts. They are more cost-effective as the price of a mobile phone is not included in the cost of the plan.

What’s more, you’re never tied down to a long-term fixed contract. This is one of the key benefits of no-contract SIM plans in Singapore, as it gives you the flexibility to transfer your SIM card between devices while retaining your current mobile number, and switch providers on your own terms.

What to Consider Before Purchasing 5G SIM-Only Plans?

Which is the best SIM-only plan to buy in Singapore? With the number of options available, shortlisting the best mobile plan can sometimes feel like searching for a needle in a haystack. Fortunately, there are several considerations you can use as a guide to choose the right SIM-only plan:

Overseas Roaming: While many plans focus on local data, some providers include a basic roaming allowance as a standard feature. Finding a cost-effective SIM-only plan that bundles roaming saves you the hassle and expense of buying a separate travel SIM card when you take a short trip

Where Can You Buy 5G SIM-Only Plans in Singapore?

You can purchase 5G SIM-only plans in Singapore in several ways:

It is generally more convenient to buy a SIM-only plan online as most providers will have a smooth and seamless sign-up process. There are also eSIM options so that you can use your plan immediately after purchase.

What is the Difference Between No Contract and Contract SIM-Only Plans in Singapore?

Contract and no-contract have different commitment levels and benefits. The right SIM plan recommendation for you will depend on whether you prefer long-term perks or complete flexibility.

What is the Difference Between a Prepaid and Postpaid SIM-Only Plan?

The primary difference between postpaid and prepaid SIM-only plans is when you pay and how you’re billed for the data you use.

Would You Recommend a Prepaid or Postpaid SIM?

Both prepaid and postpaid SIMs have their pros and cons. Which is the best SIM-only plan to buy in Singapore will depend on your own requirements.

 

Feature Prepaid SIM-Only Plan Postpaid SIM-Only Plan
Payment Model Pay in advance for your mobile service. Pay at the end of each billing cycle (usually monthly). You have an agreed amount of data, calls and SMS for each month, with additional fees if you exceed your usage limits.
Usage Limits You only pay for what you've loaded onto your account. You have an agreed amount of data, calls and SMS for each month, with additional fees if you exceed your usage limits.
Convenience Requires manual top-ups to maintain service, and you must keep track of expiration dates. Offers seamless, continuous service with no need to repurchase a plan each month.
Additional Perks Generally offers less data and fewer perks, but allows you to only pay for what you use. Is typically bundled with additional perks like roaming, streaming subscriptions, or caller ID.

For users who are on a strict budget or only need to use their phone occasionally, a prepaid SIM-only plan is a suitable option. However, for the average user, a postpaid SIM-only plan provides a more convenient, seamless, and ultimately better value-for-money experience.

How Do SIM-Only Plans Work with eSIM?

Most modern SIM-only plans offer an eSIM option so you can use the plan without having to install a physical SIM card. Here’s how eSIMs work with SIM-only plans:

  1. Purchase: You select a SIM-only plan and choose the eSIM option during the checkout process on the provider's website.
  2. Activate: Instead of waiting for a physical SIM card, you'll receive a unique QR code or activation details, typically via email.
  3. Install: On your eSIM-compatible phone, you simply scan the QR code to download the virtual SIM profile directly to your device.
  4. Connect: The plan is activated instantly. Your phone automatically connects to the network, and you can begin using your data, calls, and SMS immediately.

Providers like Maxx offer SIM-only plans with eSIM compatibility right out of the box, with options for free physical SIM delivery if the user prefers.

Do SIM-Only Plans Work for International Travel?

Yes, SIM-only plans can work for international travel. Some providers offer convenient international data add-on packs at a fixed cost, while other plans, like those from Maxx, include a roaming allowance as a standard feature.

If you are a frequent traveller who visits the same countries, the best 5G SIM plan for you would be one that covers all your destinations so that you do not have to constantly switch providers in different countries.

Do SIM-Only Plans Have Benefits Other Than Data?

Of course. Besides a generous data allowance, many SIM-only plans offer a range of additional perks.

Common Mistakes When Choosing a SIM-Only Plan

Be wary of making these common pitfalls when choosing between the current SIM-only mobile plans available in the market and selecting the best SIM-only plan for your needs.
