Can i put old sim card in new phone

Yes you can put an old sim card in a new phone and it will definitely work, as long as the new phone is not carrier locked or locked to a specific network.

This is the first and foremost you need to look out for, is the new phone carrier locked, and if the sim card is compatible with the new phone in the case of micro sim and Nano sim.

So let’s take them one after the other with an explanation.

1. You cannot put the sim card if the phone is locked

If the new phone is locked to a specific network and the the sim card is from another network, definitely the sim card will not work in the new phone unless the new phone is fully unlocked.

Let me give you an example.

You have a sim card of AT&T network, and you bought a new phone which is locked to T-Mobile network. Sometimes you will see a sim card inside the phone, but you chose to use your old or main sim card.

So you removed your old AT&T sim card from your old phone, and insert it into your new phone which is locked to T-Mobile network. After you have powered the phone, you will see that it won’t show any network in the phone.

The reason for this is because the phone is locked to T-Mobile network and no any other network will work in the phone apart from T-Mobile network or sim card.

This is why most of these networks will put their SIM card into the locked phone because no another sim network will work in the phone except for their network.

In this situation you will need to unlock the phone, and unlocking the phone isn’t free and the cost will be high if you want to unlock the phone after one month or two months of buying the phone.

This is one major factor that answers the question of today, can i put old sim card in new phone.

However, if the new phone is unlocked, then you’re good to go because the old sim card will definitely work in the new phone.

3. In the case of 5G network

You bought a new phone which is a 5G network phone, your old sim card doesn’t have a 5G network, and you’re the type that mostly or sometimes make use the mobile data.

What the essence of using a 4G network sim card in a phone that has a 5G network?

Honestly it is a complete nonsense as long as you country has a 5G network. I don’t see need or the reason why you should use a 4G sim card in a 5G phone whereas you can get a 5G sim card around you or within your environment.

In this type of situation, I don’t recommend you using the old sim card in the new phone, instead you have to get a new 5G sim card and do a sim swap.

This is another factor that determines this question of “can i use my old sim card in my new phone”.

Now let me explain what sim swap is all about.

The Sim Swap

The sim swap simply means swapping your old sim to a new sim card, and it will still retain your mobile number.

This can only be done by your network. So if you have a micro sim card or you don’t a 5G network sim card, the only way of solving this problem is by swapping your old sim card to a new one.

You only need to contact your network provider and request that you want to swap your old sim card to a Nano sim or a 5G sim card. You will give them your mobile phone number and they will do the job for you.

This involves transferring your sim information or data to a new sim card and remember, it will retain your phone number.

SIM swap is free or a small token though it depends on one’s country or location. So instead of using an old SIM card in your new phone, you better do a sim swap and have a new sim card for your new phone.

So these are the factors that answer the question we have today, can i put old sim card in new phone. Just go get a new sim card and do a sim swap, and you’re good to go.
