5G SIM-only plan

In partnership with Singtel, the Pro 5G & Ultra 5G are 5G NSA SIM-only plans that offers the most powerful 5G NSA network in Singapore. Experience ultra-fast speeds, ultra low latency, and better bandwidth.

Speed is always an important consideration. At ZYM, we constantly strive to optimize our network so you can enjoy the best speeds.

Our 5G NSA network speeds can be found below
👉 Theoretical >1Gbps
👉 Typical Downlink 100Mbps – >1Gbps
👉 Typical Uplink 35 – 90 Mbps

Speeds may vary depending on devices, population density, and other environmental factors. Speeds may also be affected when indoors or when underground.

Overall on average, 5G NSA speed is still significantly faster than 4G.

It is worth pointing out the two main iterations of 5G: NSA and SA.

5G Non-standalone (NSA) reuses existing 4G facilities for certain aspects of communicating with mobile devices, with cutting-edge 5G radio systems performing the actual communication with 5G devices.

On the other hand, 5G Standalone (SA) works on an independent network designed and deployed from the ground up solely to support 5G.

Compared to 4G, 5G SA delivers twice the responsiveness, 30% faster uploads, and strengthened authentication and encryption capability. With much greater bandwidth and near instant responses, 5G SA will enable revolutionary applications like self-driving cars, real-time immersive entertainment, and massive IoT (Internet of Things) connections.

However as of current, ZYM mobile only supports 5G NSA.

Simply go to and look out for Pro 5G or Ultra 5G plan. Then, follow the steps by steps guide to complete the sign up process.

Of course you may! Simply drop a message to to request for an upgrade of plan to 5G.

Alternatively, if you already existing Value 4G or Max 4G plan, we may get a 5G addon in ZYM Mobile app. Kindly take note that 5G addon is not available to Starter 4G plan subscribers.

One more thing. For upgrading existing plan to 5G plan, you may need to forfeit your current plan's special rate / promotional offer (if any).

If you are still in doubt, always drop us an email to

You must have a 5G handset in order to use 5G plan. We recommend customers get 5G handsets from us as they have been certified to be compatible with our 5G network.

ZYM 5G NSA is running on both 2.1GHz and 3.5GHz spectrums. 3.5GHz spectrum should provide higher theoretical speeds compared to the 2.1GHz spectrum.

Yes, our 4G network will still be available for our customers.
Rest assured that our 4G network will not be impacted by our 5G rollout.

No. You do not need a new SIM card to use 5G NSA.
