When the Wi-Fi goes down or you are working on the move, turning your phone into a personal hotspot is one of the simplest ways to stay connected. But many still ask, "Can I use a SIM card as a mobile hotspot?"
The short answer: Yes, absolutely. Almost every modern SIM card, especially those from SIM-only plans, can be used to share your mobile data with other devices through a process called tethering. This means you can connect your laptop, tablet, or even a friend’s phone to your mobile network using your phone as a portable Wi-Fi router.
Today’s SIM-only plans with cost effective data packages in Singapore make it easy to turn your SIM card into a mobile hotspot that keeps you connected wherever you are. The key lies in picking the best 5G SIM plan with generous data, strong network coverage, and True 5G access.
SIM-only tethering refers to sharing your mobile data connection with other devices. When you activate the hotspot feature on your phone, your SIM provides the internet connection while your phone acts as the access point.
Here is what happens:
Unlike dedicated Wi-Fi routers that require separate broadband subscriptions, SIM-only tethering makes use of your existing plan. It offers flexible connectivity without extra cost.
All it takes is switching on your hotspot setting. As long as your SIM plan includes a healthy amount of data, you can share your connection anytime you need.
There is a reason more users are relying on their SIM’s mobile hotspot for daily work, study, and entertainment. With the rise of SIM-only plans with low cost monthly subscriptions in Singapore, tethering is now a realistic alternative to home Wi-Fi or mobile routers.
Here is why it makes sense:
Finding the best SIM for hotspot depends on how you use your data — whether you stream videos, work remotely, or manage multiple devices. These are some of the key features to compare when choosing from SIM-only plans with cost-effective data packages in Singapore.
Tethering quickly eats through data, so the best 5G SIM plans are ones that come with large allowances, ideally 400GB or more.
Plans that include True 5G connectivity deliver faster speeds and lower latency, making them ideal for streaming, gaming, and online meetings. Many providers such as Maxx and M1 already offer these benefits at affordable prices.
When you rely on tethering, affordability matters. The good news is that there are many SIM-only plans with low-cost monthly subscriptions in Singapore that combine generous data bundles with fast speeds.
You pay only for what you use — data, calls, and roaming — making these plans great for everyday use as mobile hotspots without unnecessary add-ons.
If you travel often between Singapore, Malaysia, and Indonesia, consider a plan that includes regional roaming. Maxx’s True 5G options, for example, cover these countries under one plan. These affordable SIM-only make cross-border tethering smooth and stress-free.
Your connection is only as strong as your signal. Since SIM-only tethering depends on your network, check that your provider offers stable coverage in your area.
Maxx, powered by M1, is known for its reliability and high speeds, which makes it an excellent choice for consistent hotspot use.
If you use a secondary phone or tablet as a dedicated hotspot, eSIM activation is convenient. It lets you enable your mobile hotspot digitally without swapping physical SIM cards, ideal for freelancers or anyone managing multiple devices.
