Mozillion Bewertungen 

Joined thinking it was a good deal, cheap and uses EE which is the better signal in my area. Firstly disappointed they don't have an app for your account. My main issue is the complete lack of customer service. I decided on day 14 that I no longer wanted to stay, so within the cooling-off period. Four days on and no reply to my email. Tried calling but gave up after 15 minutes. The cancel button on the account page doesn't work, but that could be due to me being in the first month of a one month term, or could be deliberate so people can't cancel. So buttons don’t work, emails ignored, long wait times on the phone… I would go elsewhere!

On hold for 54 minutes and I hung up, left voicemails unanswered, cut the phone off after just 48h over just £3 - avoid this company it's terrible.

just discovered that i am still being charged after porting out to another provider in November 2025 :(
no response to emails and struggling to get through on phone.

Overall, Mozillion have great offers and the kill your bill feature is amazing. I have already killed my first bill.
The porting was efficient and happened when they said it would.

The reason I took one star off is the fact that my network entirely went down. Zero e-mail communication and lack of live support make this really hard to navigate. I was on hold for about 20 minutes and finally spoke to someone who did fix the issue but couldn’t really tell me what was wrong.

It runs of EE’s network which makes it really reliable and has some good coverage. I wish there was a better app with it all that would allow easier access.

I’m happy so far as it’s a great price for the plan I have but there is room for improvements.

Very disappointed. I switch networks to Mozillon network. Over a week I
do not receive SIM card behind scheduled day.
I cannot make many call over week, still wait 10-days
I am very unsatisfactory. Patrick

Currently in Greece, trying to connect to a non existent eSIM, in spite of having an email saying it would all be automatic on arrival. We have now spent upwards of 90 minutes trying to navigate the system and speak with a human. Minimum of 3 days for an email response, 30 minutes plus on hold to speak to a human and unable to leave an answerphone message. Just not good enough. Not how I want to spend my holiday.

I have been asked to supply further information. I have searched in vain to find the elusive QR code to allow me access to the data I purchased for my holiday. I have emailed (Y06ONB and WOX76L yesterday and on Monday XVZWB6) No reply to anything.
Monday’s email was to try to upgrade my phone - give them more money! Trying to access help via the online platform regarding my travel eSIM proved fruitless and (as I’ve read in other reviews) very frustrating. Likewise trying to call (from my partner’s phone because I have little data) and being kept on hold for over half an hour. The option to leave a message didn’t work.
I’ve spent all the time I’m prepared to spend on this.

All I wanted to do was give you more business & more money
but you are too stupid for that
Now once the contract is finished you will lose me forever.

There is literally ZERO support from Mozillion if something goes wrong and you need a human to resolve it. No one picks up when you call their support hotline. No one replies to any queries or tickets sent via their live chat and email.

Just try it for yourself before consider purchasing any of their products or subscriptions.

I ordered an eSIM and was told it would be sent within 24 hours. It has now been over 72 hours, and I still haven't received it. I have called customer service many times, waiting on hold for 30 minutes each time, but nobody ever answers the phone. It is clear they really do not care about their customers. I would absolutely never recommend them.

Communication was first class from start to finish. Would highly recommend this company

Changed 4 contracts over to mozillon trying to save money on my monthly payments, so far everything is going well and the coverage hasn't changed because I was originally with EE and mozillon are on the same network .

My sim is supposed to include data roaming in Spain but I’ve had no data whatsover there for the entire 4 days of the trip. I messaged Mozillion nearly a week ago but despite an auto response saying they’d reply within 1 working day there’s been no reply at all. Feeling ripped off, especially as I’ve paid for the entire 24 month contract upfront.

Bad start - tried using the kill your bill feature on app and got charged but never received the gift card. On phone to customer services on day 1 of being a customer.

Then arranged for my old number to port across - got notification it was successful but it hasn't been: I now can't text or use data. Back on the phone to customer services for a second time in just three days of being a customer...

Also hold music is dreadful!! Please change it - I wouldn't wish it on anyone.

Overall very pleased since changing to Mozillion however it does take a while if you have a problem or an issue for it to be sorted due to having only communication through e-mail. Eventually I had good service but took days and days.

I took out a new contract with this company and was informed the handset I chose was out of stock. I asked them to cancel the order and suddenly, the handset then became available after all.

I asked them not to despatch the new handset until i was back in the country in two weeks time. I received written confirmation of this from them.

But then, I got an email advising my handset was on its way. I contacted them again. They told me they would stop the delivery. They did not. I then asked them to ensure my number was not transferred until I was back in the country, as previously agreed.

Then, my old phone was cut off because Mozillion did none of the things they said they would. I cannot access the new phone because I am out of the country.

I asked them to escalate the complaint a week ago and have had zero response. I have had to use my partners phone every day and waited 15-30 mins on hold to this company and never got through. I have sent several emails and heard nothing.

Avoid, avoid, avoid.

Informative website, easy to use, great value product and speedy delivery of order.
Excellent customer experience all round - Highly recommended
