Do i need a new sim card for 5g (Or probably not)

Do i need a new sim card for 5g or probably not because my 4g sim card is compatible with a 5G network.

This can be quite confusing when planning to buy a new phone which supports the 5G network, and you have an old SIM or a sim which you’re not sure that will support or work in your 5G mobile phone.

This is one first major question that will pop into your head, do i need a 5g sim card for my new 5g phone. So let me explain this to you based on my experience when I bought my new samsung galaxy s21 ultra.

Do i need a new sim card for 5g?

You may not necessarily need a new sim card for 5g except if your sim card is old and also not compatible with the 5G network.

If you look at the answer above, I didn’t state yes or no and I have a reason for that. I’m not entirely focusing on a particular country or region writing this very topic of do i need a new sim card for 5g, I’m focusing on the general public.

In some countries or regions, you need to upgrade your sim card to a 5G sim before you can receive a 5G network coverage in your mobile phone, while in some countries, your previous 4G sim card is already compatible with the 5G network.

Immediately you slot in your 4G sim card into your new 5G phone, it will display a 5G network on your mobile phone. However, this is not the case everywhere and all the networks.

For example, in the Uk, network providers mostly will require a user to get a 5G enabled sim card to use in it’s 5G mobile phone. Even the likes of T-Mobile mobile in the United States requires their users to buy a new 5G sim card unless their previous sim has a SA 5G which is compatible with the 5G network.

do i need a new sim card for 5g

The case is quite different from the likes of AT&T network which states that a user’s previous sim card should definitely work fine in a 5G mobile phone except if the sim card is way too old. Maybe you purchased the sim card seven years ago and it doesn’t have the USIM features.

In some countries in Europe, you will definitely need to get a new 5G sim card in order to have a 5G network in your 5G mobile phone. Mostly it requires a sim swap or sim replacement as some may call it, and it is all for free without any charges whatsoever.

So this is why I didn’t necessarily go on to say yes you will need a new sim card for 5g or probably no you will not need a new sim card for your 5g mobile phone cause it all depends on your network provider. And this is the best answer to this very question of do i need a new sim card for 5g cause it is wrong to say yes or no.

What you need to do

In this case, the best place you need to get the best and accurate answer is to contact your network provider and inquire do you need a new sim card for 5g.

Yes, you have to give them a call or send a message to them and inquire if you need to get a new sim card for 5g or probably not as your previous sim card will definitely work in the 5g phone.

In my own case, I searched for this very question of do i need a new sim card for 5g and I didn’t see a valid answer at all, immediately I called my network provider to inquire if I can use my 4G sim card in my new 5G mobile phone.

They said no, and requested that I need to purchase a new 5G compatible SIM card for my samsung galaxy s21 ultra cause my previous sim card isn’t compatible with the 5g network.

I had to do as they requested and got a new 5g sim card for my new 5G mobile phone.

Do i need a new sim card for 5g Verizon

You don’t need a new sim card for 5g if you’re a Verizon user, your sim card should work in a 5G mobile phone except if your sim card is outdated and too old.

This was the statement from Verizon when I inquired if a user can use any sim card other than the 5g sim card in a 5G mobile phone. However, as long as you have a sim card that worked with the 4G LTE network, it should work in a 5G phone as well.

Again they stated that if a user’s 4G sim card didn’t work in a 5G phone, then the user should head over to any Verizon store and get a new 5G sim card for the phone.

Do i need a new sim card for 5g AT&T?

You don’t need a new sim card for AT&T, except for the fact that you have to obtain a plan or service that includes a 5G, and you’re good to go. If maybe after obtaining a 5G plan and still you couldn’t see a 5G coverage on your phone, then you need to buy a 5G compatible SIM card for your phone.

Buying a new brand phone from a network providers usually comes with a free 5G sim card if the phone is a 5G mobile phone, with this there’s no need using your previous or old sim card in the 5g mobile phone. 

However, the mobile phone will be carrier locked to that very network. If you buy directly from Apple, Samsung or probably an unlocked phone, there’s a high tendency that you will need to buy a new 5G sim card for your new 5G mobile phone.

Will 5G work on 4G phones

Yes of course, 5G sim card will definitely work on 4g phones though there won’t be any 5G coverage or features in mobile phone.

If you’re trying to ask if indeed will a 5g sim work in a 4g phone, the answer is yes cause definitely a 5g sim will work perfectly fine in a 4g mobile phone.

But if the question is will 5g work on 4g phones, that is if you can get a 5g coverage in a 4g phone, I’m sorry that will never work except for when you buy a 5g enabled mobile phone.

However, you will not receive any 5g coverage or features in your mobile phone, and the internet speed will not increase if you’re using a mobile data for your browsing and downloading.

You can use the 5g sim card to make calls, receive messages, just that you will never see a 5g features in your 4g mobile phone because it doesn’t support it unless you upgrade your phone to a 5g enabled mobile phone.

If to say will it work in a 4g phone, the answer is yes and a big one.

Do i need a new sim card for 5g? There’s a high chance that you will need a new 5g sim card especially if you have an old SIM card or maybe your 4g sim card isn’t compatible with the 5g network.

All in all, you should contact your network provider for information as to whether you should get a new 5g sim card or probably not.
