TPG Network Mobile Plans From $20 to $30
In our database, we're comparing 11 mobile plans priced between $20 and $30 a month on the TPG network from
8 providers -- including Vodafone-branded plans, which run on TPG's infrastructure. Most plans in this range
include unlimited talk & text, plus one data-only option. As with our other tier pages, we split
"genuine" plans -- where the current price equals the regular price -- from "promo-only" plans that revert
to a higher regular price later. 6 of the 11 plans below are genuinely $20-$30 long-term;
the other 5 are introductory offers. TPG-network coverage varies by area, so check the
TPG mobile coverage page before you commit
to a plan.

Plans genuinely $20-$30 long-term
TPG network coverage: Every plan on this page runs on the TPG network (this includes plans
sold under the Vodafone brand, which also uses TPG infrastructure). Coverage and speed can vary a lot by
location -- check the
TPG mobile coverage
map for your area before signing up.
Best value on this page: Among plans with talk & text, Lycamobile's M
plan remains the standout at $0.33/GB on a regular/ongoing basis (120GB, regular price
$40/month, currently $20/month as a promo). Among plans that are genuinely $20-$30 with no price hike,
Lebara Mobile's Small Data Only Prepaid Plan still leads at $0.55/GB (40GB
for $22/month). Vodafone's Small Data SIM Only Plan remains the best data-only pick at
$0.33/GB (60GB for $20/month, genuine, no promo). For unlimited data, see felix's plan below.
Read the fine print: 5 of the 11 plans below only cost $20-$30 for an introductory period
and then jump to a higher regular price. Vodafone's $60 Prepaid Plus Starter Pack remains
the steepest jump on this page -- it only qualifies for this price band on its $25 intro price, then more
than doubles to $60/month regularly, well outside the $20-$30 range this page is built around. We haven't
called it out as a "best value" pick for that reason, even though its intro-price cost/GB looks competitive.
Always confirm the ongoing cost with the carrier before signing up.

Frequently asked questions
What is the cheapest TPG-network plan between $20 and $30 in your database?
In our database, felix's Unlimited Data SIM-only Mobile Plan, Lycamobile's M plan, and Vodafone's Small Data SIM Only Plan are all tied at the lowest advertised price of $20.00/month. Of these, only Vodafone's Small Data SIM Only Plan is genuinely $20 long-term with no promo -- it's also the cheapest regular/ongoing price on the whole page.
Which TPG-network plan in this range is the best value per GB?
Among plans with talk & text, Lycamobile's M plan is the best value using regular/ongoing prices at $0.33/GB (120GB, $40/month regular, currently $20/month as a promo). Among data-only plans, Vodafone's Small Data SIM Only Plan matches that at $0.33/GB (60GB for $20/month) -- and it's genuine, with no promo hike. Among talk & text plans with no promo trap, Lebara Mobile's Small Data Only Prepaid Plan leads at $0.55/GB (40GB for $22/month).
Are all these plans genuinely priced $20-$30 long-term?
No. In our database, 6 of the 11 plans are genuinely priced $20-$30 with no increase. The other 5 -- felix's Unlimited Data plan, iiNet's Large Plan, TPG's Large SIM Only Mobile Plan, Lycamobile's M plan, and Vodafone's $60 Prepaid Plus Starter Pack -- start in this range only as an introductory promo price and revert to a higher regular price afterward. Vodafone's $60 Starter Pack has the steepest jump, reverting to $60/month -- double the top of this page's price band. Always check a plan's ongoing/renewal price before signing up.
Is there an unlimited data plan in this price range on the TPG network?
Yes -- felix's Unlimited Data SIM-only Mobile Plan is $20.00/month as a promo (reverting to $40.00/month regularly), with unlimited data, talk and text. Because it's unlimited, it can't be ranked by cost per GB, so we've pinned it separately rather than including it in the ranked tables.
Are there any data-only plans in this price range?
Yes -- Vodafone's Small Data SIM Only Plan (60GB for $20/month, genuine, no promo) is the one data-only plan in the $20-$30 TPG-network band. It's kept in its own table since data-only and talk & text plans aren't directly comparable.
Prices and data allowances shown are current in our database as of August 2026 and reflect advertised carrier pricing at time of listing. Where a plan has an introductory promo, we show both the current and regular price so you can see the true long-term cost, along with a monthly-equivalent figure for plans that don't bill on a 30-day cycle. 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.
