Pros & cons

Pros

  • Fixed pricing with no mid-contract price rises, giving customers certainty over the full contract term
  • Runs on the EE network with uncapped 5G speeds and 99% UK population coverage
  • Free EU roaming included across 41 countries on all plans
  • No credit check required for SIM-only plans, with flexible 1-month rolling contracts available

Cons

  • Limited to the EE network only, so customers in areas with poor EE coverage will need to look elsewhere
  • Relatively new brand compared to long-established competitors like Fonehouse or Mobiles.co.uk
  • Some customer reports of slow response times from customer service during busy periods

Overview

Mozillion is a UK-based mobile virtual network operator (MVNO) that sells phone contracts and SIM-only plans on the EE network. Based in Brighton, the company was founded by a team with over 75 years of combined experience in mobile retail and telecommunications.

As an accredited MVNO on EE's infrastructure, Mozillion offers uncapped 5G speeds and coverage reaching 99% of the UK population. The single-network approach allows the company to negotiate competitive pricing that often undercuts going direct to EE.

Mozillion differentiates itself through fixed pricing with no mid-contract price rises, free EU roaming across 41 countries, and a SIM-only range that requires no credit check. The company sells new handsets on contract from Apple, Samsung, Google, and other brands, with financing available through Affirm. Customer service is handled by a UK-based team, and the company is authorised and regulated by the Financial Conduct Authority.

Cashback & Offers

Mozillion does not offer traditional cashback deals. Instead, the company focuses on competitive upfront pricing and fixed monthly costs with no mid-contract price increases.

Our Verdict

Mozillion offers a compelling proposition for customers who want access to the EE network at competitive prices. The fixed pricing guarantee is a genuine differentiator in a market where most providers increase prices annually, and the inclusion of free EU roaming and uncapped 5G adds real value to every plan.

The main limitation is network choice. As an EE-only MVNO, customers who need Vodafone, Three, or O2 coverage will need to look elsewhere. However, for those in areas with good EE coverage, Mozillion consistently offers deals that undercut going direct to EE, particularly on SIM-only plans where no credit check is required.

With a Trustpilot rating of 4.2 out of 5 from nearly 5,800 reviews and FCA authorisation, Mozillion is a legitimate and trustworthy option. If EE suits your coverage needs and you value price certainty, Mozillion is well worth considering.
