Locked vs Unlocked Phone: What is the Difference?

Before anything else, let’s be clear about the type of “Locked vs Unlocked” phone that we are pertaining about. Basically, locked phones are phones that only work with a certain telecom cellular carrier company. Example, you bought a Samsung Galaxy S10 from T-Mobile. That specific phone will only work with a T-Mobile SIM card for its cellular communication feature to function properly. If you try a different non-T-Mobile SIM card, you will get an error “Phone Not Allowed: MM#6 Error.” This error means that you are prohibited from using a different SIM card other than T-Mobile. This is the case for locked phones.

On the other hand, unlocked phones will simply accept any SIM Card from any telecommunication company that works and functions in your specific country. For example, an unlocked phone will work with either a T-Mobile, Sprint or Verizon SIM card. Unlocked phones are simply not anchored, tethered or linked to any carrier.

Unlocked Phones – Everything You Need To Know

When it comes to unlocked phones, there are other means that refers to a phone being unlocked. Other than it being locked to a single carrier, unlocked phones could also mean a phone that has its bootloader unlocked.

To be precise, the bootloader is software that runs as soon as the phone is booted. This bit of code executes even before the operating system starts to run. It can instruct your operating system to load normally if it meets approval. So basically, a locked bootloader is the manufacturer weighing in about whose operating system you should use.

Android Phone Rooting

If you value that ability to install custom ROM to your phone or the ability to ROOT it, then you would want a phone with an unlocked bootloader. Cases like this are the reasons why it is important to know these terms. Otherwise, you might end up having trouble later on if a misunderstanding occurs.

Telecom Carriers and Their Take to Unlocking Phones

As long as you know better than to install shady modified software on your device, it does seem that having both your SIM card and your bootloader unlocked is the way to go. However, it is important that every consumer should be aware and be informed about the Federal Communications Commissions take on this.

According to FCC’s statement on February 11, 2014, “CTIA-The Wireless Association adopted six standards on mobile wireless device unlocking (“the commitment”) into the CTIA Consumer Code for Wireless ServiceOpens a New Window” If you want to know more about this, simply click here.

This includes AT&T, Sprint, T-Mobile, U.S. Cellular, and Verizon. Although, certain requirements must be fulfilled first.

  • Usually, the phone must be paid off or the contract fulfilled.
  • AT&T will only allow five phone unlocks per account each year. This may actually seem like a lot but probably not for a large family.
  • One year is the maximum wait time for prepaid phones to become unlocked after activation.
  • The account commonly has to be with the same carrier still. For non-customers and former customers, it can be done “at a cost.”
  • Payment status does not apply to military personnel who can present deployment orders.
  • Phones that have been lost or stolen are ineligible.

Final Thoughts…

Physically, both types of phones are the same. The key difference is the software setting that prevents the use of another cellular network in locked phones.

If you can afford the upfront cost of an unlocked phone, the answer seems clear. What are locked and unlocked phones when it comes to rooting or custom installation of ROMs?

It really is much less restrictive to start out with your SIM card and bootloader unshackled if you can afford it. If the cost is prohibitive you have to decide how much these factors are worth to you, or how much effort you are willing to put into circumventing the locks. If you’ve rooted, unlocked a bootloader, or installed a custom ROM before, your chances of success are probably greater. If you are risk averse, it might not be for you.

  1. My moto e4 from Wireless_Experts_Inc was unlocked and worked well on the Fido net for about 18 months. But now it has become LOCKED with Verizon. Since it was not purchased from Verizon they were not willing to unlock it for me. I am still hopeful that Wireless_Experts can fix it. Ian
