When you buy a phone from a mobile network, it usually comes with that network’s SIM card and a contract that runs for a year or two. The monthly price then includes paying off the handset. A SIM-free phone is the alternative: you buy the handset on its own and choose your mobile plan separately. Here is what that means and when it saves you money.
What is a SIM-free phone?
A SIM-free phone is exactly what the name suggests: a mobile phone sold without a SIM card or contract, straight from the manufacturer or a retailer. It is usually also unlocked, which means it works with any network. You pay the full price of the mobile phone up front (or in instalments from the retailer), then add a SIM card or eSIM from the provider of your choice.
SIM-free has nothing to do with “jailbreaking” or “rooting”, which means modifying a phone’s software to install apps from outside the official app store. A SIM-free phone runs the normal, unmodified software.
Advantages of a SIM-free phone
- Freedom to choose your network: you can shop around for the best SIM-only deal and switch providers whenever a better offer comes along.
- Often cheaper overall: SIM-only plans are much cheaper than contracts that include a phone, and the savings often outweigh the handset price over two years.
- The exact phone you want: you are not limited to the models and storage options a single network sells.
- Upgrade on your schedule: buy a new phone whenever you like, or keep your current one longer, without waiting for a contract to end.
- Easier travel: an unlocked phone can use a local SIM or a travel eSIM abroad instead of expensive roaming.
Disadvantages
- You have to pay the full handset price, which can be over $1,000 for a flagship phone.
- Network contracts sometimes include discounts or extras, such as streaming subscriptions, that you don’t get with SIM-only plans.
- If you choose a cheap plan, you may need to check that it supports the 5G bands and features (such as Wi-Fi calling) your phone uses.
What has changed since 2012?
SIM-free buying has become much more common. Most networks now offer SIM-only plans, and in some countries locking has been restricted — in the UK, for example, Ofcom has banned networks from selling locked phones since December 2021. At the same time, the physical SIM card is giving way to the eSIM, a digital SIM built into the phone that you activate by scanning a QR code or through an app. Since the iPhone 14, iPhones sold in the US have no SIM tray at all. With an eSIM, switching providers can take just a few minutes.
Is a SIM-free phone right for you?
If you can afford to pay for the handset up front, a SIM-free phone with a SIM-only plan is usually the cheapest and most flexible option. If you prefer to spread the cost, compare the total price of a phone contract with buying the phone in interest-free instalments and adding a SIM-only plan. And when you upgrade, don’t forget to sell or recycle your old phone.

Honestly, I never thought that having a sim free mobile must be another way to save money. There are many country that uses sim card in there phones and they end up wasting so much money. Thanks for sharing this information it is very useful.

I’m glad you liked the post, Tracy Ann. It all depends how you feel about making a large payment every month, compared to paying for a phone in full upfront. Many people prefer to have extra disposable income each month.

Actually it’s pretty common in some countries to purchase SIM free phones. Customers get to choose their own favorite phone network but will have to pay the full price for the phone.

Another concept helping the SIM free mobile to be popular is the SIM only contracts. This means you will only have to contract regarding the sim card and no mobile phone is considered in it. It’s an excellent way of shifting from one network to another whenever someone gives any exciting offer. As no mobile phone needs to be changed it is much easier for someone to shift just changing the SIM card. Generally there are varieties in the tariffs and charges among the different operators. Users now can choose any of them according to their preferences and likings.

SIM free mobile is good for easy using mobile and be free from operator contract. Mostly, all CDMA operators provide SIM free mobile service which includes good strength of bandwidth and high quality voice system.

Interestingly in New Zealand (where I once lived) then all phones are SIM free. But this isn’t a good thing – they are all locked into a network and because it is such a small country there aren’t many networks (just two I think) so choice is extremely limited.

I don’t think it will reduce our expenses cause many operators are now giving a flexible plans for users to cash them.

The biggest advantage of SIM free phones is that you are not committed to any contracts. Which gives you a whole lot of options and the ability to switch anytime.

I think it’s a lot cheaper to have a sim free phone even if you have to pay full price for the handset. The advantage is that you can use your phone according to your budget and not have to pay a fixed amount every month. Most of the time the phone networks overcharge you anyway and if you’re not a heavy phone user then this is the way to go.

Most people will choose an unlocked phone if they can, but I guess if you find a good offer on a locked one that doesn’t matter anymore.

In India, we always get mobile phones and SIM cards separately. So we can chose our mobile from any company and get a SIM from any telecom service providers. SIM free mobile concept will be good from a customer point of view for sure.

Another big benefit is when you are travelling. If you have a SIM free phone you can simply buy a pay as you go SIM in the country that you are travelling to rather than having to pay the outrageous roaming costs.
