3G Closure

3G IS RETIRING

GOODBYE, 3G

At Mercury, our mobile services are delivered through the Spark Mobile Network. By the end of 2025, 3G will no longer be available; which means if your device relies on the 3G network, you will no longer be able to connect to the network for calls, texts, or data. This is part of a global move to improve technology and make sure everyone can access the fastest, most reliable service available.

WHAT DOES THIS MEAN FOR YOU?

If you’re using a 3G network device
Your mobile services will stop working once 3G is shutdown. This includes calls, texts, and data usage.

If you’re using a 4G network device
If you have received a notice from us - Your device may be relying on the 3G network for some connectivity and may need to be upgraded to ensure continuous connectivity. Use the device compatibility checker below to confirm if your mobile is 4G-ready.

Upgrade to 4G or 5G
To keep your mobile service running smoothly, you'll need to upgrade to a 4G or 5G-ready device. This will give you access to faster internet speeds and a more reliable network.

Better Coverage

You'll get improved network coverage across New Zealand, with Spark’s 4G network reaching around 99% of New Zealanders.

*Please note that coverage on other mobile networks may differ.

Faster Speeds

4G and 5G networks are transforming the way we connect, bringing you faster internet speeds that make downloading, streaming, and browsing a better experience.

Future-Proof Your Connection

4G and 5G networks offer a more reliable service, meaning smoother video streaming with less buffering and fewer dropped calls when you’re catching up with friends and family.

CHECK IF YOU NEED TO REPLACE YOUR MOBILE PHONE

Not sure if your device is 4G ready? The models affected may vary, but Mercury Mobile customers can check by texting "3G" to 550.

You will get an SMS response that provides information about your device's compatibility with the 4G network and VoLTE capability.

Both the Short-Code message and response messages are FREE for our customers.

Have a question?

What is 3G?

3G, or "third generation," was one of the first mobile networks to support internet browsing and app use. It was a big step up from 2G, which mainly handled calls and texts.

Why is the 3G network being phased out?

The 3G network is being phased out to make way for newer technologies like 4G and 5G, which offer faster speeds, better coverage, and a more reliable service. The current 3G network relies on limited radio frequencies, which are essential for the rollout of 5G, particularly in rural areas. So, just like many mobile network operators worldwide, Spark has decided to shut down its 3G network to concentrate on rolling out 5G coverage across Aotearoa New Zealand.
Phasing out 3G will improve mobile technology and ensure that customers get the best possible experience.

When will the 3G network be shut down?

The 3G network will be phased out towards the end of 2025. After this date, 3G devices will no longer be able to connect to the network for calls, texts, or data.

What happens if I am still using a 3G device?

If you're still using a 3G device after the shutdown date, you will no longer be able to make or receive calls, send texts, or use mobile data. To keep connected, you'll need to upgrade to a 4G or 5G-ready device.

What if I need to upgrade my device?

There are plenty of 4G or 5G-ready devices available, head over to your local electronics store to explore your options.

What happens if I don't upgrade my device?

Depending on your device, you may no longer be able to make or receive calls, send texts, or use mobile data or may experience intermittent issues depending on your location. To keep connected, you'll need to upgrade to a 4G or 5G-ready device that is compatible with all of Spark's 4G bands.

Will my mobile number stay the same if I upgrade my device?

Yes, your number will remain the same when you upgrade to a 4G or 5G device.

I cannot afford to buy a new device but I want to stay connected, what are my options?

We understand that upgrading to a new device can be a significant expense. While we do not sell phones directly, there are a few options you can consider:

Mobile Device Promotions: Keep an eye out for special promotions or discounts from retailers that may help reduce the cost of upgrading.
Payment Plans: Some electronic retailers offer payment plans that allow you to spread the cost of a new device over time, making it more manageable.

What should I do if I’m a vulnerable person using a mobile device provided by Mercury?

All of our Vulnerable Mobile devices support VoLTE and will work beyond the 3G Shutdown. These devices are reviewed on a regular basis and we will be in contact if your device needs to be replaced in the future.

I bought my phone overseas; will it work on 4G?

As phones bought overseas or from local importers have different specifications, neither Mercury nor Spark can guarantee that it will work on the Spark network. If you can't connect your phone to 4G, try downloading the latest software update. If that doesn't work, you may need to replace it.

Why did I receive this message if my device is 4G compatible?

Some devices that have been purchased from overseas or were imported from overseas by retailers may not be compatible with all of the required 4G bands and/or 4G calling on the Spark Network. If you have received a notice from us advising that your device is not compatible, you will need to upgrade your device to ensure continuous connectivity.
