What our customers say

Partners in and around Belfast

Larne

month on our bills at the time and I enjoyed being able to help others make similar savings when I joined as a Partner. I’ve never looked back and still enjoy helping others pay less on their everyday bills. Learning to help others do what I do is, and has been, an education, but one I also enjoy. After I was injured at my work and put out to pasture, it was this business which gave me the purpose to continue to help others and I am eternally thankful for it. It’s also given me three holidays and a brand new car.

UW Partners in and around are people just like you, who earn an extra income by introducing others to UW and helping them sign up as customers. They also help people to become a UW Partner and start earning an income by recommending UW to their friends and family.

Yes, of course – over 1,386,585 customers and 70,000 UW Partners already do. We’re also regulated by the energy regulator Ofgem, the telecoms regulator Ofcom, and the Financial Conduct Authority. We’ve been doing business for nearly three decades and are listed on the London Stock Exchange, which means we’re one of the UK’s largest publicly-owned companies.

A SIM-only deal gives you data, minutes, and texts for a set monthly cost. However, you don’t get a new phone like you would with a mobile phone deal – you just get the SIM.

Of course. You can use our mobile SIMs with any unlocked handset or any phone on the EE network too.

The easiest way to tell if your phone is unlocked is by inserting a different SIM card from another network into your mobile. If you’re able to connect to the internet, make calls, and send text messages, your phone is likely unlocked.

If you don’t have another SIM card from a different network provider, you can also check by going into your phone’s settings.

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.

Unlimited data means that you don’t have a cap on your data allowance each month in and the rest of the UK. There are no restrictions on how much data you use, so you won’t have to worry about using up all your allowance.

Our Unlimited data, calls and texts SIM-only plan is perfect for surfing the internet, taking video calls, or even streaming media, as you can use as much as you need.

We’re offering EU roaming as part of our Unlimited tariff, so you can take your unlimited data abroad and use up to 14GB of it at no extra cost. It’s part of our Roam like Home service, which lets you use your allowance in 45 locations across Europe. You can also send texts and make calls back to the UK as you would normally with your allowance. Our Unlimited tariff has no data usage cap when browsing in the UK.

A family plan is a special family SIM-only deal that covers multiple SIMs. With a family plan, you can choose a deal that ensures your whole household is connected, all as part of a single convenient bill.
