Perfect, so long as you're technology literate!

I am 78 years old and not tech literate, so my son had to do it for me. However, everything went like clockwork, as it suggested. I only hope now is that I can use my mobile phone in Llandudno to make a call, as this is the reason I have changed from Vodafone, where I couldn't even book a taxi to get me back to the railway station.

Cannot even reply to a junk SMS with "STOP" without being charged

Hi,

I'm not impressed that standard features seem to be broken.

e.g.
I often get SMS messages to my phone from places like my bank or credit card company. As an example, today I got a text from a credit card called capital one from the number 60073.

There is an option in these SMS messages to unsubscribe from them by sending the word "STOP" back to the sender.

When I try this I get a warning "This will cause charges on your mobile account" with an option to send or cancel. This is despite having a prepaid SIM with unlimited SMS and Calls.

Q1. Why would I be charged to send this reply back. It seems wrong. I should be able to opt out of marketing SMS with no charge to myself.

Q2. If I click the option "Send" on this warning screen (rather than cancel) I get an error message on my phone saying "Not Sent. Check Options". When I click on "Check options" I get the options "Resend" or "Delete". If I choose "Resend" I go into a loop.

Deeply Unimpressed!

Great performance, value and customer service.

80GB on EE for £6/m, a great value sim only tarif and on the best network.

Seemless transition and porting of old number.
No app, which is fine. I have many more times data allowance than I actually use so unless you coast near your data limits that you need to monitor there's no real need for one.

Had to request a new esim because I'd tried to install and uninstall it on more than phone mid number porting. Doh! My fault but dealt with my dumb ass promptly and professionally. Excellent service so far.

Amazed by Mozillion

Amazed by Mozillion. I have been with EE for over 14 years now and finally took the plunge to change to Mozillion. I'm amazed by the savings I've made and equally surprised by the quality of the broadband. Will certainly be recommending others to join up too. 5 stars all the way. 😊

Easy to set up.

Easy to set up.
No problems getting number switched over.
App for kill your bill had to be reinstalled to make the first voucher purchase which was a little faffy, but not particularly a problem.
Have now used the app for voucher purchase from Aldi and used said voucher against my bill 👌🏻

Hi, thank you for your feedback. SIM cards usually take 1-2 working days to arrive so my apologies if it has taken longer - if your SIM has still not arrived, please do contact us on help@mozillion.com and we can organise for a replacement to be sent to you via tracked delivery.

Kind regards
