Review summary

Created with AI, based on recent reviews

Evaluating 2,412 reviews, reviewers overwhelmingly had a great experience with this company. Customers frequently highlight the excellent pricing, finding deals to be very competitive and offering substantial savings compared to other providers. Many people also praise the efficient delivery service, noting that products arrive quickly and in perfect condition. The ease of switching providers and porting numbers is also a recurring positive point, with many describing the process as smooth and straightforward. However, some customers also noted issues with customer service, experiencing slow responses or conflicting information. There were also occasional problems with product availability, where ordered items were not in stock, and some users reported difficulties with SIM card functionality or receiving their physical SIMs. A few people also felt that the "unlimited" data plans had hidden caps, leading to unexpected service interruptions.

Connection process was straight forward, although the physical SIM didn't work it was easy enough once they sent an eSIM via email. Paying up front for 24 months makes it a really good deal. Just ho... See more

Tested it for one month

1. Extra Charge: I tried Mozillion for one month. They tried to charge me two months fee for one month use.
2. Lousy Service: very poor indoor signals. They say that if you go over your data limit, your speed will just be reduced, but instead, you end up with no data at all.
3. 5G signal and speed are acceptable.

Reply from Mozillion

Hello, thank you for your feedback. All one month rolling plans require 30 days notice to cancel as per our standard terms.

Regarding signal, our network covers 99% of the UK population - we do have a Coverage Checker available on our site so you can check Mozillion indoor and outdoor coverage.

Your data allowance resets each month and if you do need more data, you are able to purchase a data add-on from within your Mozillion Dashboard.

Excellent customer service.

There were some teething problems with porting the number, but the support in resolving them was excellent. What stood out in particular was having the same person throughout, who responded quickly and helped manage the issue through to the end — something that’s quite rare these days.

Not to be trusted

I was told that my new bandwidth cycle would begin today. I ended up, on a Sunday, with no Internet & had to walk a long way to Sainsbury's for their wi-fi. When I cancelled online on 19 April, I was told I had to pay for up to 18 June. I am NOT going to. Incidentally, they throttle the speed of - or even block - anyone who exceeds 500 GB. I went back to Smarty, where I have just got 343 Mb/s using the Three network. I think Mozillion are crooks.

Excellent service

I am just over halfway through a 24-month contract for a new phone and SIM contract, and I have absolutely nothing but praise for Mozillion. Both service and price excellent. Also recently purchased a Sim only deal for my wife, which was carried out very professionally, thank you.

Smooth - Good pricing - Great coverage

Super smooth experience migrating to this provider. Quick and easy.
The pricing is excellent compared to other providers I’ve used.
I previously had coverage issues. Now I have reliable voice and data pretty much everywhere I go.

I had never heard of Mozillion before…

I had never heard of Mozillion before but they had a really good deal for an iPhone last year and I went for it and I don’t regret it at all. I’m very happy with my phone- it came exactly as expected and I’m on the best network (EE). I’ve not had to contact their customer service since I placed my order, but when I had asked a question at the time they always replied quickly.
