FAQs

Does unlimited data really mean unlimited?

Yep, it really does. Unlimited data means there’s no speed restrictions and 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.

Can I get a new phone when I join UW?

Yes, we’ve got a great selection of phones as well. See our full range 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.

How do I add more Unlimited SIMs?

You can take up to three additional SIMs when you have an existing Unlimited plan. Log into your online account or the mobile app to add more SIMs yourself, or give us a call on 0333 777 0777 and we’ll help out.

What network does UW use?

We work with the EE Network to ensure broad coverage and signal strength across the country.
