Switching to Mozillion was incredibly straightforward. I ordered my SIM online and it arrived the very next day. The process of porting my old mobile number over was smooth, with no issues at all. I love that I can keep track of everything via their online account, making it a stress-free experience. Highly recommended for anyone wanting a quick switch

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.

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.
