What is a SIM Card?

We know that it may sound like an obvious question. However, do you know what a SIM card is and what it stands for? Well, the acronym SIM stands for Subscriber Identity Module. Technically, it is a small chip that identifies your network and mobile phone number. When you insert a SIM card into a phone, it should automatically connect to the corresponding network. After that, you can make and receive calls, send and receive text messages, and connect to mobile data.

The thing is that sometimes we need to use our SIM cards on another device. It could be because your current cell phone is too old and you want to change it, or maybe it stopped working and you got a new one. The question is, can I use the same SIM card on another phone? Probably you do not want to change your phone number.

Well, the answer to that question is yes, and no. It will depend on whether that other cell phone is unlocked or not.

Let’s understand what it means:

Is my Cell Phone Locked or Unlocked?

Let’s start by stating what it means that a cell phone is locked.

If the cell phone is locked, it means that it will only work on one specific network. Consequently, if you insert a SIM card that is from a different carrier, it will simply not work. Some companies tie the subscriber ID number in the SIM card to the serial number of a cell phone. It is to be sure that you will not switch to another mobile provider. However, in several countries around the world, it is illegal now to sell locked cell phones, and it is more and more common to find unlocked phones in the market.

New Unlocking Rules:

• USA: Carriers must unlock phones after 60 days (FCC mandate)
• EU/UK: All phones sold unlocked since 2021
• Canada: 90-day unlocking rule

As you can imagine, this issue does not happen with unlocked phones. They allow you to use any carrier, so you can insert any SIM card in the phone and it will work.

It is very beneficial to have an unlocked phone, especially when you usually travel abroad. The roaming fees are most of the time too expensive, and the best thing to do is to get an international SIM card to use in that other country.

It is just possible on an unlocked phone.

Knowing now this information, another question arises:

How can I know if my cell phone is unlocked?

There are two main ways to know if your cell phone is locked or unlocked. The one that works either for Android or Apple phones is the next:

You will need a SIM card from a different carrier. Then you need to turn off your cell phone and remove your SIM card (for some models you will need a removal tool or a paperclip). After that, insert the other SIM card (from the other carrier) and turn on your phone.

The first thing you will notice if the cell phone is unlocked is that it recognizes the SIM card by connecting to the network and finding reception (check the signal bar on the upper side of the screen).

However, to be completely sure we recommend you make a call. If it connects, then congratulations! Your cell phone is unlocked. Otherwise, if it does not connect, it means that the phone is locked and tied to the first carrier. A message showing an error will appear, also explaining why the SIM card you inserted before does not work.

If you do not have another SIM card, we have another option for you to know if the cell phone is locked or not.

For Android phones:

• First, go to the Settings option in your phone’s menu.
• Find the option that says “Connections”.
• Go to Networks, Mobile Networks, or Cellular Networks. The name will depend on your phone model and the version of the software.
• Select Networks Operators.
• Wait until the phone searches for available networks, it can take some time.
• If a list of available networks appears, the phone is unlocked.
• If it shows only one network, or if the Search Networks option is unavailable in the menu, then the phone is locked.

For iPhone phones:

• First, go to Settings.
• Tap on Cellular.
• If you see a Cellular Data option under the Cellular menu, your iPhone is unlocked; otherwise, it means it is locked.

How to unlock a locked cell phone?

If you have a locked phone and you want to unlock it, one thing you can do is to contact your mobile provider. Of course, they will charge you a fee for the service.

If they do not offer the service, which is more likely, there are also third-party companies that can do the process. They will charge you a fee from $5 to about $25, depending on the cell phone.
