Does unlimited data really mean unlimited?
Yep, it really does. Unlimited data means no data caps when you use your SIM in a mobile phone in the UK. Just keep in mind that our fair use policy does apply – and when roaming in Europe, your data is capped at 14GB each month.
How does a SIM only deal work?
A SIM only deal gives you data, minutes and texts for a monthly cost. The difference, however, is that you don't get a new phone – you get the SIM, and just the SIM.
Can I use my own phone when I join UW?
Of course. You can use our SIMs with any unlocked handset or, as we work with EE, any phone on the EE network too.
Find out how to insert our SIM in any handset.
Can I get a new phone when I join UW?
Yes, we’ve got a great selection of phones as well. See our latest phones here. To get a new phone with your SIM, you’ll need to give us a call on 0333 777 0777.
Can I keep my phone number when I join UW?
Yep, simply contact your previous network provider or text 'PAC' to 65075 to get a code which will allow you to bring your current number over to your new SIM. This won’t disrupt your service either.
Find out more about how to keep you current mobile number.
How do I add more Unlimited SIMs?

What network does UW use?
We work with the EE Network to ensure broad coverage and signal strength across the country. You can check your network coverage here.
