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

eSIM QR codes didnt work
Was sent 3 eSIM QR codes which wouldn't work so i was sent a SIM in the post the next day which worked. Was a bit stressful not being able to use my new phone but whenever i rang i didnt have to wait long for someone to answer and everything else i.e. ordering, receiving my new phone and keeping my number was seemless.

The process was quick and easy and no dramas. I was on the Three Network via SMARTY and well when it came upgrading my phon they refused although credit rating was excellent and never faulted on any payments. They stated I could try again in 90 days but I would rather go where I am valued and MOOZILLION made me feel my custom was welcome and valued. Fast delivery and no issues to report. So far so good. Would definitely recommend to everyone.

Mozillion's "Unlimited" 5G package really isn't...
Abysmal service...after signing up for Mozillion's £22 p/m "Unlimited" package , I got a formal warning when my data downloads approached 500GB two weeks into my first month, and connection was then blocked the following day with no refund offered. £22 for just 16 days service is an absolute joke!
Update to Mozillion's reply - I've been completely *disconnected* after 16 days, not just limited download speeds. Zero service!

Reply from Mozillion
Hello, thank you for your feedback. Like many other operators, Mozillion has a Fair Use Policy in place on Unlimited data plans to ensure fair access to network resources and consistent service for all of our customers.
For the tiny minority of very high data users that go over 500GB in a single month on the unlimited plan, this may result in data speeds being limited for the remainder of the month as this goes against what is deemed fair, reasonable and acceptable personal use for this plan.
We received your email response yesterday afternoon and have noted this accordingly.
Kind regards
Mozillion Customer Team

Exceptional customer service
Exceptional customer service. Requested a replacement eSim using their dashboard, called them requesting them to expedite the request, spoke to Laura without any waiting, and the replacement eSim turned up by email within a couple of minutes. Quick & easy!
