Telstra Network Mobile Plans From $20 to $30

In our database, we're comparing 25 mobile plans priced between $20 and $30 a month from 13 providers that all run on the Telstra network -- Telstra itself plus MVNOs and resellers like Boost Mobile, Pennytel, TeleChoice, Tangerine Telecom, ALDI mobile and more. This list is limited to plans billed per 28 days, per 30 days or per month, so every price below is directly comparable. As on our other plan pages, we've ranked the table by regular (ongoing) price rather than the advertised "now" price, so you can see what you'll actually keep paying. 16 of the 25 plans are already priced at their regular rate with no promo involved; the other 9 revert to a higher price later, in some cases nearly triple. A handful of those also come with a temporary "double data" bonus that expires on its own separate schedule -- we've called those out individually below rather than counting the bonus data as part of the plan's long-term value.

All 25 plans, ranked by regular price (lowest first)

Sorted by regular/ongoing price, lowest first; ties broken by cost per GB on that regular price (using each plan's long-term data allowance, not any temporary data boost), best value first. Highlighted rows are already priced at their regular rate -- no promo involved. Rows showing a "Now" price include a limited-time discount that reverts to the regular price shown; a few also note a bonus data allowance that expires separately.

Frequently asked questions

Prices and data allowances shown are current in our database as of August 2026 and reflect advertised carrier pricing at time of listing. This page is limited to plans billed per 28 days, per 30 days or per month for direct comparability, priced between $20 and $30, and ranked by each plan's regular/ongoing price rather than its current advertised price -- where a plan has an introductory discount, both prices are shown. Plans, prices and inclusions change frequently, and details are entered into our database manually so errors are possible -- we do not guarantee the accuracy of any price, allowance, or other detail shown. Always confirm the final price and all plan information directly with the carrier before signing up.
