What Does 'Unlocked' Mean?

“Unlocked” mobile phones are phones that are not tied to a specific carrier’s network, meaning they can be used with a SIM card from any service provider. This gives you the flexibility to switch carriers as you please, without having to purchase a new phone. Importantly, as of December 2021, all new mobile phones sold in the UK are required to be unlocked. This move has empowered consumers, offering them greater freedom and flexibility in their mobile phone choices. Stay connected with your current network provider by keeping the SIM card from your current phone!

What is a SIM Free Deal?

A SIM Free deal refers to purchasing a mobile phone without a SIM card, giving you the freedom to choose your own carrier or continue using your existing one. In other words, these mobile phones come “free” of any SIM or contractual obligations. This is particularly advantageous for those who want to use their phone internationally or switch carriers frequently, as you’re not bound by any network-specific limitations. Buying a phone outright can also often be cheaper, as it means that you’re free to buy the cheapest phone and pay for the cheapest SIM contract independently of one another. Buying a SIM-free phone has in the past usually meant buying one that is also unlocked by default, however as of 2021 new mobile phones cannot be sold locked to a network anyway. Some second-hand smartphones may in rare cases still be locked to a specific network, however these come at a heavily discounted rate to reflect this.

Can I still buy a SIM card from The Big Phone Store?

Yes, you can still buy a SIM card for your new SIM-Free phone from us on a PAYG plan, subject to availability. For our pay as you go SIMs, click here. Our SIMs are provided by a range of network providers and can be used in any of our unlocked phones.

SIM Free Vs Contract Phones: A Comparison

SIM Free Phones

  • Pros: Greater flexibility, no long-term commitments, easier to upgrade or change phones.
  • Cons: Higher upfront cost for the phone, no carrier subsidies.

Contract Phones

  • Pros: Lower upfront cost for the phone, often includes additional perks like data or call packages.
  • Cons: Bound by a long-term contract, usually 24 months, penalties for early termination.
The choice between SIM Free Phones and contract phones boils down to your needs and preferences. If you value flexibility and freedom, a SIM Free phone is the way to go. However, if you don’t mind committing to a long-term contract for a low cost handset, then a contract phone could be more suitable.

Why Buy Refurbished?

Refurbished phones offer an excellent blend of quality and value. These mobile phones undergo rigorous testing, repairs, and certification to ensure they meet the same functional standards as new devices Buying refurbished not only saves you money but also contributes to sustainability by giving a second life to devices that might otherwise end up as electronic waste in landfills. The Big Phone Store provides a wide range of smartphones from major brands, such as Samsung, Google, Sony, and of course the Apple iPhone. We also have plenty of cheaper options available from OnePlus, Motorola, Oppo, Honor, and Xiaomi.
