All you need to know about a SIM only deals

SIM only plans offer the most flexible, cost-effective way of paying for your data, calls and texts, without the additional cost of a new phone. These plans, when compared to the same data plan with a new phone on contract, are far cheaper, over half as much - even on the same network.

Not only are the plans cheaper, but they also come with very short-term contracts, from a 30-day rolling plan, giving the flexibility to chop and change, or up to 24-months for the ultimate in savings. The longer the term, the greater the savings.

A SIM only deal works like this: the price you pay covers the monthly cost of the data, minutes and texts, plus any free EU roaming – there is no new mobile phone included. Mozillion (or any other provider) will send you a new SIM card by post normally, or by email to download an eSIM (a digital sim) to your existing phone, depending on the type of SIM you order, to get you up and running.

You need to ensure you phone is unlocked to use a SIM only plan from another network provider, alternatively you can keep your existing SIM card if you decide to change tariff to a SIM only plan with your same network provider.
