If you have a SIM card from a GSM network, your phone is unlocked. To find out if your phone is GSM unlocked, you can remove the SIM card and check the back of the phone. If the phone has a GSM logo, it is unlocked.
Before we start
What is a SIM card?
A SIM card is a small card that is inserted into a mobile phone to allow the user to make and receive calls, as well as access their phone’s basic features. Most modern mobile phones are unlocked, which means that you can use any SIM card in that phone with no issues. However, if your phone is locked to a specific network, you will need to get a SIM card from that network to be able to use that phone.
What Carriers Are GSM Unlocked
Some people might say that unlocked phones are not as reliable as phones that are locked to a specific carrier. However, there are a lot of unlocked phones on the market that are very reliable. This is because the phones are designed to be used with any carrier that uses GSM networks. So, even if a phone is not directly made by a specific carrier, it will still work on most GSM networks. If a phone is not made by a specific carrier, it is called a ‘unlocked phone’.
Unlocked phones can be a great choice for people who want to use a phone with a different carrier. For example, someone who wants to switch from a T-Mobile phone to an AT&T phone. Or, someone who wants to switch from a MetroPCS phone to a Cricket phone. Unlocked phones are also a good choice for people who want to buy a phone secondhand. For example, someone who wants to buy a phone secondhand from a person who is using an unlocked phone.
Overall, unlocked phones are a good choice for people who want to use a phone with a different carrier. They are reliable, and they are a lot cheaper than phones that are locked to a specific carrier.
Are All Unlocked Phones GSM
Back in the day, phones were only available on GSM networks. However, more and more phones are now available on both GSM and CDMA networks. For example, the iPhone X is available on AT&T, T-Mobile, and Verizon, while the Google Pixel 2 is available on AT&T, Sprint, and Verizon. A universal phone can be used on any of those networks, so it’s not really a issue.
However, there is a downside to this. If you want to use a CDMA network like Sprint or Verizon, you’ll need to get an unlocked phone. Unlocked phones are available on both GSM and CDMA networks, so it’s not really an issue.

Can I Sim Unlock My Phone Myself
To unlock a mobile phone, you need to turn off the phone, take out the SIM card, and turn on the phone without the SIM card. After a few minutes, a message will appear on the phone asking you to insert the SIM card. Once you insert the SIM card, you will need to write down the IMEI code.
Can You Still Use a GSM Phone
Many people are transitioning to 4G LTE service, but there are still some people who use GSM phones. GSM phones use different frequencies than LTE, so they can’t connect to LTE networks. However, some rural carriers still offer 2G GSM service, which is still supported by rural carriers. 3G UMTS devices, otherwise known as 3G GSM or WCDMA, still work on AT&T and T-Mobile.
