When you purchase a smartphone directly from a carrier, it also includes a sim and a data plan. Typically, such phones come with a monthly installment plan so you don’t have to pay all the money outright.

As said above, sim-free Samsung phones don’t come with a preinstalled sim. For instance, if you purchase a Samsung S20 sim free, Samsung a21s sim free or any other Samsung phone models online, you’d have to pay the full price for it instantly and it won’t come with a preinstalled sim card.

However, it must be noted that even though the phone doesn’t come with a preinstalled sim, it might still be carrier-locked. That means you will only be able to use the device with a specific carrier. To have the freedom of using the phone with any carrier of your choice, your sim-free phone should also be unlocked. Most of the sim-free phones are unlocked and ready to be used with any carrier, though.

Many users welcome sim-free phones because they don’t have to pay hefty data plans for the included sim. Moreover, the buyer pays the full price in the beginning, so they have immediate ownership of the device.

Part 2: Advantages and Disadvantages of Samsung SIM Free Phones

There are numerous benefits to purchasing a sim-free phone such as Samsung galaxy s10 sim free and Samsung a41 sim free, let’s discuss them right now.


  • First and foremost, you’re not tied to a single carrier when you purchase a sim-free phone. You have the freedom to sell the phone and get a new phone whenever you feel like it. You can upgrade your data plan or network provider whenever you want.
  • You pay the full price of the phone at the beginning, so you get immediate ownership of the device — you’re free to do anything with it then.
  • Last but not least, it’s much easier to travel abroad with unlocked sim-free phones. As carrier-locked phones can’t be used with other sim cards, you will have a hard time using your locked smartphone with foreign sim cards.


  • If you purchase a sim-free phone, let’s say a sim-free Samsung S10, you will have to pay the full price for it right away — and that’s the only downside. Many people don’t have the budget to pay the full price in the beginning, so purchasing a sim-free phone could be a challenge for them.
