New sim free phone
Researched different deals for the phone I wanted and this company came out best. Easy to navigate website and choices re size of software etc. Placed order (on a weekend) and received the phone within 3 days and regular updates given. Would use them again.

It was easy from start to finish
It was easy from start to finish, the sim arrived next day and the transfer of my old number 48 hours later. Brilliant.
Not impressed so far…
Only been with them over a week and I’m
Not keen at moment. Every step is tricky, more: phone takes days to deliver comparatively to other companies who can do next day… Grumbles: the eSIM didn’t arrive either and I had to chase it, which is 24 hours to get a response as no direct chat other than a bot. Finally got the eSIM, found the data wasn’t activated so had to contact again. Number porting set for a week after I’ve received the phone despite advance ordering.
I hope it gets better!

Cheapest route to be on EE
Seamless, easy process, well communicated with & it’s a lot cheaper way to stay on the EE network.
The only drawback is that the Mozillion app doesn’t seem to work (iOS user).
Great service.
First experience of using Mozillion, but the experience was simple and straightforward from start to finish and the pricing (in comparison to other mobile providers) was great value. Would definitely recommend.
