To begin a brand new year, Heartland Boy typically likes to get his finances in order first. This is very much akin to performing a spring cleaning before the lunar Chinese New Year. Therefore, he has been strategizing on how he could further reduce his discretionary expenses in 2018. One of the low-hanging fruits that he has identified was his monthly mobile phone bill. After some research online regarding the latest deals, he realised that he was still sitting on a cell phone plan that belonged to an era when competition in the telecommunications sector was less stiff. As a result, he has been overpaying his mobile phone bills for several months. Over the first weekend on 2018, Heartland Boy finally paid a visit to his telco provider. Here is how he managed to save over $300 per year by switching to a SIM-only mobile phone plan.
Comparing Mobile Phone Plans
For starters, SIM-only mobile phone plans are postpaid plans that do not bind the consumer to a fixed-term (eg: 2-year) contract. They were introduced in early 2016 as the incumbent providers (Singtel, Starhub, M1) reacted to news of a fourth operator entering the market. The beauty of SIM-only mobile phone plans is their potential to slash your handphone bill by at least half. Therefore, they were heavily promoted as the cheapest mobile phone plans in Singapore. Here is a comparison of Heartland Boy’s previous I-Reg plan vs mySIM³ 20 plan that he switched to recently.

Advantages of SIM-Only Mobile Phone Plan
1. Huge savings without downgrading consumption
From the comparison table above, it is evident that the savings achieved by SIM-only cellular plans are huge. By switching from the I-Reg plan to mySIM³ 20 plan, Heartland Boy will be able to save approximately $45 per month on his handphone bill. The actual saving is less as Heartland Boy used to enjoy a 30% corporate discount on the previous mobile plan, but they are still significant nonetheless.
The beauty is that this material saving was achieved without any downgrade to his mobile phone consumption habit. With the advent of VOIP technology and instant messaging platforms, his I-Reg plan had become bloated as a result. Heartland Boy probably utilised only 10% of the talktime and SMS allocated under the I-Reg plan as these services were conducted on Whatspp instead. Despite under-consuming the I-Reg plan, his mobile bill remained at $61+. By switching to mySIM³ 20 plan, his monthly local data increased by 1GB while his bill decreased by almost 70%. Simply great value for money!
While there is no further 30% discount for the mySIM³ 20 plan offered to corporate clients, they still get to enjoy free Caller ID, which is equivalent to a value of $5 per month. Henceforth, unless Heartland Boy exceeds the usage provided under mySIM³ 20, he expects his monthly mobile plan to be a grand total of $20 nett. The last time his phone bill was this cheap was years ago when he was still a student!
2. No Contractual Obligation
Unlike conventional mobile plans of the past, SIM-only mobile phone plans do not bind customers to a fixed period of 24 months. This implies that budget-conscious consumers now enjoy the flexibility to shop around for the best mobile phone plan in Singapore. If you have noticed, Heartland Boy opted to be contracted for a period of 12 months. By trading away some form of flexibility, Heartland Boy managed to bump up his local data from 2GB to 5GB. Somehow, he finds this to be a sweet spot; just the right amount of data allocated and a relatively short contract period to honour.
Heartland Boy has been raving about the merits of SIM-only mobile phone plans thus far, so what’s the catch?
Disadvantages Of SIM-Only Mobile Phone Plan
No Handphone Subsidy
Consumers who switch to SIM-only mobile phone plan would have to forgo handphone subsidy that typically comes with every renewal of the mobile phone contract. This is something that Heartland Boy can live with as he finds that smartphone plans encourage too much of consumerism. Switching mobile phones every 2 years is a nice want to have but not a necessity. Even the process of selling a new phone on Carousell obtained from re-contracting can be quite a hassle. Therefore, Heartland Boy prefers to enjoy guaranteed monthly savings and only replace his mobile phone when it is absolutely shattered.

Greater Need To Monitor Usage
The other disadvantage of SIM-only mobile plan is its rigidity. Unlike previous mobile phone plans, consumers on SIM-only mobile plans are unable to pre-purchase local data to add on to their existing data plans.

SIM-only mobile phone plans do not allow for ala-carte add-ons
Therefore, if a consumer regularly uses 7 GB of local data, he or she would be better off by taking up the mySIM³ 40 plan rather than incurring excess data usage that are charged at $10.70 per GB.
Thankfully, Heartland Boy is not a heavy user of local data so 5 GB per month is sufficient. In order to avoid incurring excess data usage, he also monitors his mobile phone usage on the M1 app from time to time.

Conclusion
By switching to a SIM-only mobile phone plan, Heartland Boy managed to save at least $300 per year. All it took was 20 minutes to process the transfer of phone plan at the retail shop. The more amazing thing was that Heartland Boy brought Heartland Girl there as well. She too managed to save over hundreds of dollars on her handphone bill. This is probably yet another neat trick to impress your other half and amass valuable brownie points for use in the later part of 2018.
Update: With the inclusion of MVNO (mobile virtual network operator), Heartland Boy now thinks that Circles Life would probably offer the best value for money for a sim-only plan.
Based on the previous plan you are having, you should be able to get a discount of $500 when purchasing a phone during re-contract. You can sell the phone away to second-hand shops to cash out the $500. You are actually losing out $500-$300savings=$200. Including corporate discount, you are losing $300 ($200 + corporate savings of $100) instead of saving $300 by switching to sim only plan.
Hey,
I didn’t know I would be eligible for a handphone discount of $500! If that is really true, then I am truly disappointed at my lack of due diligence.
The 500 discount is only on highest plan dont get fooled
thanks for letting me know! i do not think the highest plan is suitable for my current consumption!
iphone x cost $1888 for the 256gb model on apple store. Using a plan of mySIM 40, you can purchase the same phone at $1380 (https://www.m1.com.sg/iphone#Plans) and cash out @ $500 difference. switching to sim only plan only benefits those whose usage is really low with no corporate discount or if they are too lazy to do the recontract every 20mths.
Hey, you are right. another reader had already alerted me to this handphone subsidy. i admit i prob did not do enough homework on this before i switched.
You can perhaps sell close to official price when it first launches. Nowadays you can’t even sell for $1700. If there no genuine buyer is around, you can only sell to those mobile shops that only offers $1600, and the price is dropping. Too many re-contracted phones as supply.
If you compares SIM plans with smartphones (mySIMe40) and SIM-only plans (mySIM20) on 5GB data, the price difference is $20*24 months which is $480; which is only $20 lesser than if you manage to sell it off at official price.
Hi there,
if you port-over your mobile phone to another telco and take Corporate Plan, there will usually be $150 – $200 off handset subsidy (depending on the plan). For your i-Reg plan, you should be able to get $200 off. Nowadays, with mobile phone portability, switching between telco is a breeze.
Hey,
thanks for the suggestion. my corporate plan is strictly with M1. so I cannot really switch between telcos. but thanks for all the suggestions. The good thing is that i am now on a no-contract plan and I stay ready to take advantage of any future price war between the operators.
It is a hassle when I recontract at Paragon (M1), take the subsidised phone to Far East and cash out.
All done within the 1-2 hours.
I rather not sell online and deal with the low ballers and any potential scammers.
I did the sums for mysim plans and it doesnt work out because there is no corporate discount for mysim plans. Unless there is, people with corporate discounts are better off with phone plans.
And not forgot, mysim plan is only a year long, I personally dont like the hassle to go down to the teleco to recontract.
Hey Dan,
it is true that there are plenty of lowballers online. it takes up an incredible amount of energy dealing with enquiries. Hence, your strategy of selling direct to the shop is definitely worthwhile.
if users on corporate plan who adopt mysim plans, it is true that there is no additional discount. the only discount is the waiver of caller ID which costs $5 per month. The customer service office told me there is no need to head down to re-contract. The plan will renew automatically although there is a 3-month period for you to cancel it when the auto-renewal is triggered. After 3 months, it is taken that you have agreed to re-contract for the entire year.
Is it cheaper to use pre-paid type?
Hi Susan,
I am not familiar with the offering under pre-paid mobile plans therefore I am unable to verify.
Heartland boy saved $300/yr. contract usually 2 yrs. so he would have saved $600. $600 vs $500 phone subsidy with contract. Is almost same. If u change phone after 3 yrs. U would have saved $900. So I think is still worth for the SIM only plan
