About Mozillion
Mozillion sells new and refurbished handsets from Apple, Samsung and Google, alongside SIM-only plans, travel eSIMs and finance options through Affirm and PayPal. Customers range from those wanting a new iPhone or Galaxy on contract to anyone looking to cut a monthly bill or pick up a certified refurbished phone at a lower price.
The range covers current and older devices, from iPhone 16 and iPhone 17 Pro Max through to Galaxy S25 and S26 models, Galaxy Z Fold and Flip handsets, and Google's Pixel 10 and Pixel 11 lines, sold either SIM free or as part of a bundle. Refurbished stock is graded Good, Excellent or Good As New and checked through a 90-point diagnostic before resale. SIM-only plans run from 3GB up to unlimited data on 1, 12 or 24 month terms, with fixed pricing and no mid-contract rises, and a separate Travel SIM covers use abroad without roaming charges.
Mozillion operates as an accredited MVNO on what it describes as the UK's largest mobile network, drawing on a team with a combined background of more than 75 years in mobile retail and network operations. It also runs Kill Your Bill, an app-based scheme offering cashback at partner retailers that can be put towards a customer's monthly phone bill.

What does the Mozillion 12 month warranty cover?

If a complaint remains unresolved after eight weeks, it can be referred to the Communications Ombudsman or, for financial products, the Financial Ombudsman Service.

Does a Mozillion SIM only plan require a credit check?
A Mozillion SIM-only plan does not require a credit check, making it accessible without the usual credit assessment applied to phone contracts. This applies specifically to the SIM-only plans rather than device finance.
