Ever bought a smartphone only to find it locked to a specific carrier? It literally spoils all your excitement and hinders even your basic phone perks, as you can’t switch SIMs on iPhone, travel internationally, or change networks without restrictions. That’s where UnlockBase makes its way! It’s a service that promises to unlock your phone using its IMEI number so you can use any SIM card you like. But how well does it really work, and is it even free or not?

In this guide, we’ll break down everything you need to know about UnlockBase, especially your price concerns and how to use it. We’ll also share what to do if it fails to work, along with an all-in-one alternative you can count on.

What Does UnlockBase Do?

UnlockBase is an online phone unlocking service that provides permanent SIM unlock codes based on your device’s IMEI. You simply give them your phone’s IMEI number and they generate the code that removes the carrier lock. The service supports a huge range of models, so you don’t have to worry even for your older smartphones. It claims to unlock 10 million+ phones in 165 countries, covering devices from most major brands like Apple, Samsung, Google, etc.

UnlockBase emails you step-by-step instructions once you get over the payment processing part. For iPhones, this typically means you’ll receive an email confirmation and an unlock code. After that, you can insert a new SIM card and enter the code when prompted. It also highlights customer-friendly policies involving 24/7 support and a full refund if they fail to unlock your phone.

No physical shipping is needed because everything is done remotely via your phone’s IMEI.

Is UnlockBase Free for SIM Unlock?

No, UnlockBase is not free. It is a paid unlocking service and the cost varies by phone model and original carrier. Overall, fees typically start around $10 and can go up to $200 or more. For example, simpler models or carriers might be on the low end (around $10-$20), whereas recent high-end iPhones on major networks can cost much more ($249.9 for Verizon USA).

Keep in mind, too, that you might experience some additional charges after the initial payment. In other words, UnlockBase might quote a price to begin with, then ask for extra payment to complete the unlock. While not all users experience this, it’s something to be aware of. Be sure to check the price for your specific device on their site, and watch out for any unexpected follow-up fees.
