For students, travellers and everyday users, a 28-day SIM or eSIM plan provides reliable service without long-term obligations.

What you get with 28-day plans

Telsim’s 28-day plans include:

  • 28-day expiry from activation or recharge

Matching your data needs to the right plan

Choosing the right data plan depends on how you use your mobile.

  • Light users who mainly browse, use maps and check social media may find 15GB sufficient.
  • Moderate users who stream music, make video calls, enjoy casual mobile gaming and scroll regularly may benefit from 45GB or 80GB.
  • Heavy users who stream high-definition video, play online games, work remotely or use their mobile phone as a hotspot may require 120GB or 160GB.

When comparing plans, also consider:

  • Your average monthly data usage across streaming, browsing and hotspot
  • Network coverage in your area on the Telstra Wholesale Mobile Network
  • Whether unlimited standard national calls and SMS are important to you
  • International call inclusions if you contact overseas numbers
  • Speed caps that may apply to selected 5G plans

The benefits of 28-day plans compared to long-term prepaid plans

28-day plans provide greater flexibility compared to other options.

With a 28-day plan, you can:

  • Change your plan size at the next renewal if your data usage changes.
  • Keep costs manageable without paying months in advance.
  • Trial the service before committing to a longer expiry plan.
