A new wave of technology hits with the power of 5G. It's speed, stability, and range that were previously hard to find both on the open waters and on land. But to sail with this current, do you need to replace your SIM card? Well: it depends! So before you set sail, check if your ship is ready for it!
Key information from the article:
- Not every SIM card supports 5G. Older models (pre-2016) may not work with the new standard.
- Modern SIM cards and eSIMs are compatible with the 5G network. You just need to have the right phone and mobile operator coverage.
- Replacement is only needed if: the card is several years old and does not support LTE; the phone does not recognize the 5G network despite an active plan, or the operator confirms a lack of support for new security protocols.
- If you join our Crew, you can sleep soundly! Your card works with 5G, and if you need support – our helpline will help you set the right course.
Do you need to replace your SIM card for 5G?
Before we dive into deep waters, let's answer one super important question: what is 5G?
In a nutshell: it is the fifth generation of cellular technology, which is a natural evolution of the 4G LTE network.
Compared to previous generations, 5G offers:
- speeds at which even Thor would have to hold onto the mast;
- latencies shorter than a blink of an eye;
- enormous bandwidth – the network will support thousands of devices simultaneously;
- stability that no digital storm can shake.
Under the deck of 5G, there are also several powerful technologies:
- Network Slicing – allows dividing the network into independent „layers” for various applications (e.g., online gaming, IoT, or telemedicine),
- Massive MIMO and Beamforming – which help direct the signal exactly where it's needed, like a well-trained crew.
It is worth remembering, however, that these capabilities depend mainly on the network infrastructure and your device, not on the SIM card itself.

Do you need to replace your SIM card to use 5G?
Alright, let's get to the point. So what's the deal with SIM cards for 5G – do you need to replace them or not? The answer is: it depends. Mainly on the age of your SIM card. Most modern cards (USIM or eSIM) are fully compatible with 5G. However, if you are using a very old card, it may turn out that replacement will be necessary for the network to properly recognize your device.
SIM card replacement is needed if:
- you are using a card from before 2016;
- your device supports 5G, but the phone only connects to 4G or LTE network;
- the operator confirms that the card does not support new authentication methods (e.g., 5G AKA).
Replacement is not needed if:
- you have a nanoSIM or eSIM,
- your smartphone supports 5G,
- you are within 5G network coverage.
In the Mobile Vikings network, every card issued for years supports LTE and 5G. You don't need to replace it when changing phones or switching to a new generation network.
More about types of SIM cards, you can read in a separate article.
Does an older card limit 5G capabilities?
Older SIM cards can connect to the 5G network, but they may not always allow for the full utilization of its potential. New cards, adapted for 5G, support newer security protocols and faster authentication mechanisms, which improves connection stability and cooperation with more advanced network functions.
In practice, this means that:
- an older card will allow you to use 5G internet, but may not support newer network functions;
- a newer card (USIM or eSIM) provides full compatibility with new technologies and security features.
How to check if your card supports 5G?
It's as simple as this:
- Insert the card into a 5G-enabled phone.
- Turn on mobile data and make sure that „5G/4G/3G/2G (auto)” is selected in the network settings.
- If „5G” appears in the top bar of the phone – the card is working correctly.
- If not – contact your operator.

eSIM is always riding the 5G wave!
If you want peace of mind for years, choose eSIM – the electronic version of a SIM card.
This modern solution:
- does not require plastic replacement or shipping;
- you activate in a few minutes using a QR code;
- supports all network standards, including 5G.

FAQ – frequently asked questions
How to check if a SIM card works with 5G?
Insert the card into a 5G-enabled phone and turn on mobile data. If „5G” appears in the status bar, the card is working correctly. If not – contact your operator.
Can I use an old SIM card for the 5G network?
Yes, if it is a newer generation card (USIM or eSIM). Older cards can connect to the 5G network, but they may not always allow for the utilization of all features and security of the new standard.
