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
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.
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.
The primary difference between postpaid and prepaid SIM-only plans is when you pay and how you’re billed for the data you use.
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.
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:
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.
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.
Of course. Besides a generous data allowance, many SIM-only plans offer a range of additional perks.
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.
For a definitive answer to which is the best SIM-only plan to buy in Singapore, you need to look at what truly matters: a great price, generous data, and no long-term commitment. This quick reference guide compares the top plans to help you find the perfect one.
