Phone arrived the next day & exactly as described. It’s immaculate & £170 cheaper than buying brand new. You can’t tell the difference between this & brand new. Really pleased.

Brilliant prices and truly excellent service. Ordered an iPhone 17 and sim received in 3 days and at a cost 30% less than my current provider. Only issue which is minor is constantly having to log in... See more

Frantastic Company

Great company. Website was very good with all information and options. I chose As good as new phone and looks brand new including the packaging. The delivery was very quick and the price was great too. I would definately use Mozillion again and recommend it to anyone.

Ordered my phone

Ordered my phone, number was ported over and not received my new phone resulting in current phone not working. No update on delivery a week on and still no new phone or working phone.

My experience was good

My experience was good, the order process was easy, a bit of a faff as you have to go through a loan company although interest free I feel the Mozillion should deal with everything. Porting number was a good experience my last supplier never put my original number on my phone so people kept asking if I had a new number then it would appear at their end occasionally 🤷.
Unfortunately my partner hasn’t had the same experience with Mozillion yet but I will let her do her own review.
So far I’m happy but I will point out I believe you only get the shop to drop your phone bill on a sim only contract, I could be wrong so check it out yourself I’m to old to be bothered.
I got a phone I ordered

Easy and fast

It was easy to order and delivery was very fast. Buyers should be mindful of the fact that advertised prices do not include VAT, this is added onto the bill when you order.

Excellent customer service …

Got a great deal on both a monthly package which covers myself, daughter and husband for less than just two plans with o2, also purchased travel SIMs at a great deal.

Due to my our fault I had to contact customer service a few times by phone who were extremely helpful, giving great service, thank you
