Frequently Asked Questions about SIM Only Plans

What are SIM only plans?

A SIM only plan is a mobile phone plan that provides you with a SIM card, without a device bundled in.

Maxx offers a range of SIM only bundles that are fully loaded with abundant mobile data and minutes. The best part? No contracts and no excess charges required. You can also stay informed on the latest SIM only plan promotions available at Maxx to enjoy the cheapest deal possible.

Is a SIM only plan cheaper than a traditional mobile plan in SG?

SIM only plans can be more cost-effective since they don’t include the cost of a mobile device. This means you can save money while enjoying essentials like sufficient mobile data and free caller ID. That being said, it’s important to do a comparison on the various plans and providers available in Singapore to find the best value for your needs.
