    Annual price review

    Our mobile and data plans include an annual price review and may increase in line with CPI in July each year. CPI measures household inflation and is released by the Australian Bureau of Statistics. We'll use the CPI for full year to March quarter and any increase will be rounded to the nearest dollar and occurs within your July billing cycle. We'll let you know before any changes take effect.

    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.


    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.

    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.

    Plan speeds

    Download speeds for your included data on the Basic Mobile plan are capped at 250Mbps on our 4G and 5G network, rolling out from August 2022. With an Essential and Premium Mobile plan your included data comes with access to our fastest download speeds on our 4G and 5G network. Speeds may vary due to factors such as location, distance from the base station, local conditions, concurrent users, hardware and software configuration and download/upload destination. For 5G coverage information, check coverage map.

    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. Check your device's compatibility.

    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 and MMS to premium numbers, some satellite numbers, and use overseas.

    International Calling Pack

    30 minutes of international calls and unlimited international SMS, to all countries, are included in our Upfront Mobile plans. Once you’ve used the 30 minutes, you can add an International Calling Pack to your plan from $10 per month. You can add or remove it at any time in the My Telstra app. International Calling Pack includes an allowance of calls from Australia to standard international numbers in eligible destinations. View eligible destinations here.

    International roaming

    The only way to use your service overseas is by purchasing an International Roaming day pass. 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 Zone 1 and 2 packs include 500MB of data to use per day as well as unlimited talk and text. Usage expires at the end of a 24-hour day pass period. If you go over your 500MB, you can add an additional 1GB 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 destination.

    If you’re travelling to a destination where our International Roaming day pass isn’t available, you cannot use your Telstra service.

    Telstra Plus upgrade

    You're eligible for the Telstra Plus upgrade if you’re an existing Telstra Plus member or if you sign up to Telstra Plus and are on an Essential or Premium mobile plan. Telstra Plus tier upgrade will be applied within 30 days and will apply for a year aligned to membership date. Once you reach the anniversary of the relevant membership year, we'll let you know that this offer is ending and you'll be moved to the relevant tier based on your previous year’s spend.

    Cancelling your plan

    If you cancel your Telstra Upfront Mobile Plan, you will not 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 as a one-off payment.

    Changes to your plan

    Your upfront mobile 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.
