What is the difference between SIM free and SIM only?

Updated on April 28, 2026
Keeping this in view, can you put any SIM card in a SIM free phone?
A SIM free phone can come locked or unlocked. If it is unlocked, then any SIM card that physically fits will work. If it is locked, then you must insert a matching SIM or unlock the phone.
Likewise, is it better to buy SIM free iPhone? Purchasing a SIM-free iPhone means you will not qualify for the lower iPhone price associated with a contract or a carrier installment plan. If you don't want a multiyear service contract, or if you prefer to use a local carrier when traveling abroad, the SIM-free iPhone is the best choice.
Moreover, what's the difference between pay as you go and SIM free?
The main difference between them is that a Pay monthly SIM only deal includes an allowance for calls, texts and data which you'll be billed for every 30 days. A Pay as you go SIM only deal requires you to top up with credit. Neither deal includes a free phone.
What happens if you take out your SIM card and put it in another phone?
When you move your SIM to another phone, you keep the same cell phone service. SIM cards make it easy for you to have multiple phone numbers so you can switch between them whenever you like. In contrast, only SIM cards from a specific cell phone company will work in its locked phones.
