Terrible experience with Mozillion
Terrible experience with Mozillion – missing phone, poor customer service, and no support
I purchased a new EE network mobile contract through Mozillion.com on Friday 05/06/2026. I signed up for a 24-month contract and selected an iPhone 17 Pro Max. I also chose the SIM option and paid £300 upfront for the phone.
Unfortunately, I still have not received my phone.
On 11/06/2026 in the afternoon, I received confirmation that my phone had been dispatched by Royal Mail Special Delivery Next Day service before 1 PM. However, when I checked the tracking information on 12/06/2026, it showed that the parcel appears to have been sent to the wrong address and is now stuck at the Burnham-on-Sea sorting office.
I contacted Mozillion customer service several times, but after long waiting times on hold, I was told by their support team that there was nothing they could do to help resolve the issue.
I also explained that I feel I was misled by the advertising on the Mozillion website, which stated that delivery would be within up to 3 working days. This deadline passed on Wednesday, and my phone is now already several days late.
I requested to cancel the contract and receive a refund, but I was told that I cannot get my money back until the phone is returned. How can I return a phone that I have never received and which appears to be lost during delivery?
Mozillion has offered no compensation and has shown no willingness to help resolve this situation.
I am also very concerned about my credit score. Mozillion carried out a credit check in my name, and the contract was financed through an external credit company, Affirm, over 24 months. I am due to apply for a home remortgage soon and I do not want this situation to negatively affect my previously excellent credit score.
Based on my experience, I strongly recommend avoiding Mozillion. The lack of customer support, the delivery problems, and the refusal to help with a problem outside of my control have been extremely disappointing.

Great service and fantastic value
Mifi Device and SIM card arrived only working day after ordering.
SIM wouldn't connect - rang Mozillion and within 15 minutes I was fully up and running.
Great network coverage at a very low price - what's not to like?

The customer service was exceptional
The customer service was exceptional. As a new client, I am extremely satisfied with my recent acquisition of the Samsung S26 Ultra, which was offered at an unparalleled price point. The device was delivered within 48 hours, and the porting of my existing number was completed seamlessly. Furthermore, I received consistent updates via email throughout the process.

Worth it
Had an issue when ordering initially, but the customer service was excellent, fast response and resolved the issue quickly. Received the phone swiftly, the contract price and inclusions are very competitive. So far so good.

Found Mozillion on Money supermarket and thought I would see if I can get a decent signal as others were useless. Quick to receive my SIM card and transferring my number was painless. So far I have had a signal. It was an extremely good price for my needs, don’t need much being a pensioner. Fingers crossed
