Other reasons to know if your phone is unlocked: You are ready to take that bucket list trip to Europe and want to rent a SIM card while you are there because it will likely be much cheaper than roaming charges over there. abroad with your current operator. Or maybe you’ve bought a new phone and want to make sure your old one is unlocked to sell it.

Here’s how to determine if your phone is unlocked and how to request that it be unlocked from your carrier. The answers vary depending on the type of phone you have and the carrier you are on.

Carriers previously had two standards. Verizon used CDMA, which stands for Code Division Multiple Access, while AT&T and T-Mobile used GSM, Global System for Mobiles.

But most phones made after 2010 are “dual band” and have been able to work on either network as cell phone companies have expanded their 4G LTE networks. Operators will shut down their CDMA and GSM networks at various times in 2022 as they are 3G bands, so be aware that at some point in the next year you will stop being able to use any CDMA or GSM only phones. .

How? ‘Or’ What To tell if your telephone is unblocked

If you bought your phone without a SIM card, for example direct from the manufacturer or a big box store rather than by contract or from a phone retailer, it is probably already unlocked. Unlocked phones are more common than ever before, but if you’re not sure, here’s what to do:

The easiest way to find out is to insert a SIM card from another carrier to see if you can make a call.

Open a paperclip and use it to eject a SIM card from a friend or family member’s phone. Look for a small pinhole at the top, side, or bottom of the phone. A SIM card is small and can be difficult to hold, so be careful not to drop it. Unless it’s a very old SIM card, which is larger, your friend’s SIM card should fit in the SIM tray of your existing phone. If you need help, walkthroughs are available online.

No signal? Your phone is probably locked. But to make sure, restart it and repeat the steps.

You may see a message asking for a SIM unlock code. This means that your device is locked to the carrier it was originally purchased from.

If you don’t have access to another SIM card, you can take your phone to an operator store or a mall kiosk and tell them you want to know if your phone is unlocked. You don’t have to say that you are considering joining their service. Just be honest and say you’re not sure yet and would be happy to consider their business.
