Cheapest SIM-Only Mobile Phone Plans Below $10: Maximum Savings

What Is a SIM-Only Plan?

A SIM-only plan is a mobile subscription that gives you talktime, texts, and data without locking you into a phone contract. Instead of paying off a handset, you're simply paying for mobile service every month. That means you can bring your own device, avoid long-term commitments, and switch plans easily if you find a better deal.

In Singapore, SIM-only plans have grown in popularity because of their flexibility and value. With more mobile virtual network operators (MVNOs) offering affordable options, it’s easier than ever to get generous data bundles without spending a fortune.

Why Choose a SIM-Only Plan?

A SIM-only plan is one of the smartest ways to stay connected without overspending. Here’s why more users in Singapore are making the switch:

Perfect for those who already own a phone
If you don’t need a handset upgrade, SIM-only plans let you pay just for data, calls, and SMS — no extra costs for devices.

Save more every month
With no handset subsidies or hidden charges, SIM-only plans are consistently cheaper, helping you reduce your monthly bill.

No long-term lock-ins
Unlike traditional contracts, SIM-only plans give you flexibility. You can upgrade, downgrade, or leave anytime without penalties.

Customise data to your lifestyle
Whether you’re a light WhatsApp user or a heavy gamer, you can choose a plan that matches your actual data needs instead of overpaying.

Easier to switch providers
SIM-only plans make it simple to move to another telco if you find a better deal, giving you more control and freedom.

What Makes a SIM-Only Plan “Cheap”?

A cheap SIM-only plan is not just about a low monthly price. It’s about how much value you actually get for what you pay. The best affordable plans offer a strong mix of high data limits, reasonable talktime, and little to no hidden fees.

Here are the key things that make a SIM-only plan truly cheap:

• Transparent pricing: No sneaky charges, fine print, or forced top-ups.

• No contracts: You can leave or upgrade anytime, which gives you control over your budget.

• Good data-to-dollar ratio: Look for plans with at least 80GB of data under $10.

• Reliable support and coverage: Even at low prices, service quality matters.

• Useful extras: Some plans include free incoming calls, roaming add-ons, or app discounts.

Cheap plans are ideal when they match your usage without unnecessary extras. Whether you’re a student, a frequent traveler, or someone who just needs a backup number, finding that sweet spot between affordability and features is the goal.
