Can You Use Your Old 4G SIM Card in a 5G Phone?

The simple answer is yes. You don’t need to buy a new 5G SIM card for a new 5G smartphone. You can easily use your old 4G SIM card on your latest 5G phone. If your SIM card works well with 4G/LTE networks, then it will also work with 5G whenever it goes live in your country. It will work and connect to data. However, you will not get access to the 5G network.

The 4G SIM card will work properly in a new 5G phone. But, there will be some limitations. If you want to get all the experiences about connecting to the new 5G network, you will need to have a new 5G SIM. In that case, you will have to change your SIM card. Anyways, let’s take a look at what mobile carriers in the UK and US say about getting new 5G SIM cards.

1. T-Mobile (US)

This service says that 5G services will work well on 4G SIM cards. But, to take full advantage of T-Mobile’s SA 5G services, you need to get a 5G SIM card from T-Mobile.

2. Verizon (US)

According to Verizon, you can use a 4G SIM card to access Verizon’s 5G services, assuming you already have a 5G phone. You don’t need to buy a new SIM card for 5G service on the Verizon network.

3. AT&T (US)

This network says that you don’t need a new 5G SIM card to access the 5G service. But you will have to purchase a 5G data plan.

4. EE (UK)

You don’t need a 5G SIM card to access the 5G network service on this network.

5. Three (UK)

This network claims that the 4G SIM cards from Three networks are already compatible with the telco’s 5G network in the UK.

6. Vodafone (UK)

You don’t need to buy a new 5G SIM card to access Vodafone 5G services in the UK.

Do you need a new SIM for the 5G Network in India?

The straightforward answer is No. Some 4G SIM cards are forward-compatible with 5G networks. So, probably, you will get a 5G network with your existing 4G SIM. All the Indian telecom companies, including Airtel, Reliance Jio, and Vodafone Idea (Vi), have not said that you will have to buy a new 5G SIM card to access 5G services. That means we can say that we will not need a 5G SIM card in India for Airtel, Jio, or Vi. However, in the future, you may have to buy a new 5G SIM card.

India will likely implement SA 5G and roll out an indigenously developed 5G Standard called 5Gi. The new 5Gi solution could be based on a Non-Standalone 5G (NSA) infrastructure. As the 5Gi NSA solution allows Telecom operators to use the existing 4G infrastructure, we do not need to upgrade 4G SIM to 5G SIM in India.

Note: As of now, there is no official information for the following FAQs:

  • Do we need to upgrade an existing 4G SIM to a 5G SIM to avail 5G Network in India?
  • Will 5G Networks work with 4G SIM?
  • Do we need to buy a 5G SIM in India?
