Commonly Asked Questions

SIM-Only Plan FAQs

Q: What is a SIM-only plan?

A: A SIM-only plan is a type of mobile phone plan that includes a SIM card with an allotment of data, minutes, and texts. Unlike traditional phone contracts, SIM-only plans do not come with a handset, allowing you to use your own device or purchase one separately.

Q: What are the benefits of choosing a SIM-only plan?

A: SIM-only plans offer several benefits, including:

  • Flexibility: Most SIM-only plans are contract-free or have short-term commitments, allowing you to change or cancel your plan easily.
  • Cost-effectiveness: SIM-only plans are often cheaper than traditional phone contracts since you’re not paying for a bundled handset.
  • Freedom of device choice: With a SIM-only plan, you can use your existing device or choose to purchase a new one separately, giving you more control over your phone choice and upgrade cycle.

Q: What should I consider when choosing a SIM-only plan?

A: When selecting a SIM-only plan, consider the following factors:

  • Data allowance: Assess your monthly data needs based on your usage habits, such as browsing, streaming, and social media.
  • Call minutes and texts: Determine how many call minutes and texts you typically use each month.
  • Network coverage: Check the coverage map of the mobile network provider to ensure you’ll have reliable service in your area.
  • Price and contract length: Compare prices and contract durations from different providers to find the best value for your needs.

Q: Can I keep my existing phone number when switching to a SIM-only plan?

A: Yes, you can usually keep your existing phone number when switching to a SIM-only plan. The process is called a PAC (Porting Authorization Code) transfer. Contact your current provider to obtain a PAC code, which you’ll then provide to your new provider to initiate the transfer process.
