All you need to know about a SIM only Preloaded deal
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.
Prepaying for a 12 or 24-month plan offers the ultimate saving. The longer the term, the greater the savings.
A SIM only deal works like this: the price you pay covers the cost of the data, minutes and texts, plus any free EU roaming for the entire term of the contract – 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.
Let's get you signed up!
Simply select the SIM plan and term above, submit your details on the next page and choose your payment method for the full payment to be taken.
There is no credit check with Mozillion, your next step is to decide if you wish to keep your existing phone number, if you do, you will need a PAC number to complete the transfer by texting PAC to 65075. Enter the code sent to you on to our site or send it to us when you're ready to port your number over.
Once the order is confirmed your new SIM card will be sent by 1st class post, or if an eSIM, sent to your email address for instant use.
If you are keeping your number, the porting will take between 1 and 3 working days to complete.
