What Is a SIM-Only Plan?

A SIM-only plan gives you mobile services, like data, calls, and texts, without the bundled cost of a new phone. You only pay for the SIM card and the monthly plan. This gives you flexibility and can save you money in the long run.

How SIM-Only Plans Work

When you sign up for a SIM-only plan, you receive just the SIM card, which can be inserted into any unlocked device. Most SIM-only plans are no-contract or month-to-month, giving you the freedom to switch providers or upgrade your plan anytime.

Benefits Over Traditional Mobile Contracts

  • Lower monthly cost since you’re not paying for a handset

  • No lock-ins, making it easier to switch providers

  • Greater flexibility to customise your plan or cancel anytime

  • Bring your own phone, ideal if you already own a device you love
