Your month-to-month plan may change (including price and inclusions). With no lock-in, you can change your plan once a month or leave. If you leave, just pay out your device, accessories or services in full.

Telstra 5G: Telstra currently offers 5G in select areas and is progressively rolling it out to other areas. In non-5G coverage areas, you’ll automatically switch to our 4G or 3G. Check coverage map.

4GX: The Telstra Mobile Network offers 4GX in all capital CBDs and selected suburban and regional areas and is progressively rolling out to more places. In other coverage areas around Australia, you’ll automatically switch to our fastest available 4G or 3G. Check coverage map.

Typical download speeds in 4GX areas are 5 -300Mbps with category 16 devices, 5-200Mbps with category 11 devices, 5-150Mbps with category 9 devices, 2-100Mbps with category 6 devices, and 2-75Mbps with category 4 devices. Outside 4GX areas, you will switch to our fastest available 4G or 3G speeds. Speeds vary for reasons like location, distance from base stations, terrain, user numbers, hardware/software configuration, download source and upload destination.

Month-to-month plans: If you cancel your service, you will receive a pro rata refund for the remainder of your month. If you have any device, accessory or service add-ons attached to your plan, you will have to pay any remaining amount owing on your next bill.

Device Payment Contract (DPC): You must have an eligible Telstra Mobile Plan in order to have a DPC. If you cancel your DPC early, cancel your mobile plan during the device payment term or move to an ineligible mobile plan during the payment term, you’ll need to pay out your device, in full. Device discounts do not apply to cancelled DPC.

Talk, Text and Data: Excludes calls/SMS/MMS to premium numbers, 12xx, satellite numbers, content charges and use overseas.

Data usage: This plan comes with a data allowance to use in Australia. You won’t be charged if you go over your monthly data allowance. Instead, you can continue to access data up to speeds of 1.5Mbps. 1.5mbps isn’t suitable for HD video or high speed applications, and means that some web pages, social media content and files may take longer to load). In addition, heavy data users (users in the top 1% of all data users) may experience slower speeds than other users during busy periods. The speeds you actually receive may vary depending on a range of factors including your device, location, number of users and download sources. Your data allowance is for personal use in a smartphone or tablet in Australia only and the FairPlay Policy applies.

Compatible Handset: Compatible Telstra Mobile Network handset required. More info at telstra.com/device.

International Calling and SMS Pack: International calls are no longer included in any of our mobile plans. You can add an International Calling and SMS Pack to your plan for $10 per month. You can add or remove it at any time. Includes unlimited calls and SMS from Australia to standard international numbers in Eligible Countries. MMS is not included. Eligible Countries are Canada, China, Germany, Guam, Hong Kong, India, Ireland, Japan, Malaysia, New Zealand, Norway, Puerto Rico, Romania, Singapore, South Korea, Spain, Sweden, USA and UK.

International Roaming: To use your service overseas, you can purchase an International Roaming Day Pass at $5 per day in New Zealand, or $10 per day in more than 70 eligible countries. Day Pass includes 200MB of data to use per day as well as unlimited talk and text. Usage expires daily based on AEST. If you go over your 200MB, we'll add an additional 500MB for $10 for use within 31 days. A Day Pass is triggered whenever a call is made or received, an SMS is sent or if any mobile data is used in an eligible country.

If you’re travelling to a country where our International Roaming Day Pass isn’t available, you can still use your phone at pay-as-you-go rates. For more info go to telstra.com.au/international-roaming
