When shopping for a new phone, most people naturally focus on the headline price first. A lower upfront cost can look like the smarter deal at a glance.

But when it comes to real value, the better question is not just “How much does the phone cost today?” It is “How much will I pay overall?”

That is where total cost of ownership matters.

Instead of looking only at the handset price or monthly fee on its own, total cost of ownership helps customers compare the full picture over the contract period. This includes the monthly subscription, upfront phone price, any new line or port-in savings, and the overall amount paid across 24 months.

Total cost of ownership (TCO) is the total amount you pay over your contract period, usually 24 months. It includes:

Looking at TCO helps you compare the real cost, not just one part of the plan.

When choosing a mobile plan in Singapore, many people focus on the lowest upfront phone price. But this can be misleading.

A cheaper phone upfront may come with:

In contrast, a plan with a higher monthly fee may still be cheaper overall if it offers:

The key is to compare the total cost, not just the first payment.

No, a SIM Only plan is not always cheaper than a mobile plan. 

While SIM Only plans usually have lower monthly fees, mobile plans can offer lower total cost over 24 months due to discounted device prices and sign-up promotions.

For new phone upgrades, phone plans often provide better overall savings.

For example, a SIM Only plan may have a lower monthly subscription, but that does not always mean it costs less overall.

Here’s a simplified comparison using a premium smartphone:

Total savings with phone plan: $476

Even though the monthly fee is higher, the phone plan costs less overall due to lower device pricing and promotions.

This is why total cost of ownership is a more useful comparison than looking at just one number. Instead of focusing only on the monthly subscription or the handset price, customers should compare the monthly fee, upfront phone price, port-in savings and 24-month ownership cost side by side to see which option delivers better value overall.

Before choosing a plan, compare these 5 key factors:

1. Monthly subscription

Look beyond price — check data, roaming, the quality of the connectivity and benefits included.

2. Upfront phone price

A lower upfront cost can significantly reduce total spend.

3. Promotions and savings

Port-in deals and new line offers can reduce your total cost.

4. Total cost over 24 months

This is the most important number — it reflects what you actually pay.

5. Overall value

Consider the balance of:

With premium smartphones becoming more expensive, focusing only on the upfront price can lead to higher spending in the long run.

Comparing total cost of ownership ensures you:

Is SIM Only always cheaper than contract plans?

No. SIM Only plans have lower monthly fees, but contract plans can be cheaper overall when device discounts and promotions are included.

What is the cheapest way to get a new phone in Singapore?

The cheapest option is usually a phone plan with strong promotional pricing and lower upfront device cost, depending on the total cost over 24 months.

Should I buy a phone upfront or with a plan?

Buying upfront gives flexibility, but getting a phone with a plan can reduce total cost due to subsidies and savings.

How do I find the best mobile plan?

Compare total cost of ownership, not just monthly fees or phone price. Look at all costs over the contract period.
