Mozillion 30-day SIM only deals

Yes. A 30-day rolling SIM has no long-term tie-in, so you can cancel with around 30 days' notice without paying an early-exit fee.

That flexibility makes it ideal if you want to try the network, are between longer contracts, or only need cover for a short period.

Rolling 30-day plans typically carry a slightly higher monthly price than a 12 or 24-month deal, because you're paying for the freedom to leave at any time.

If you know you'll stay put for a year or more, a longer SIM only contract usually works out cheaper overall.
