Really Behind - Disappointing!

Have only just moved over to three because the sim only deals are so good but when you use the app, you feel like you’re with a telecoms company from the stone ages!

I have to enter THREE (no pun intended), separate pieces of information: phone number, email and password EVERY TIME I want to use the app!! Face ID?? A passcode perhaps?? How is it possible that a phone network provider which sells deals on the LATEST smartphones doesn’t have this technology to log in?! Very very frustrating and unexplainable....surely an easy fix?!

Had a message a couple of days ago to say app was being updated so got excited about being able to log in using the most up to date methods...but still no!! Come on Three, move with the times!!! You’re such a good provider, yet a simple thing like this makes you look amateur and totally unaware of the time’s we now live in! Please sort!!

Sorry to hear this! Please can you try and download the latest app version as we now have biometric log in enabled and you can use Face id.

100% worst Teleco app in the UK

Where to start? Well, firstly, it’s not actually an app, it’s a really poorly designed website wrapped in an imitation web browser.

Secondly, you cannot complete your “profile” unless you agree to ALL of Three’s marketing options...? 🤣 I’m stuck on 70% complete, apparently because I refuse to accept telemarketing calls! 🙄

I suppose I’m lucky I can actually login and use the “app” (judging by previous reviews, I’m in the minority here...!), but as others have said how are you not utterly, utterly embarrassed and ashamed by this app Three UK? It’s atrocious!

Suggest your technology teams view the apps from the following for a hint of what a proper app should look like: O2, EE, Vodafone, BT, Sky Mobile, giffgaff, Virgin Media, Tesco Mobile, Plusnet Mobile... need I go on?

Happy to revisit my review if you bother to make a proper app, but until then...? 🤔🤢😱


So the developed said it was a “bit harsh” to criticise this atrocious app and then suggested live chat. Seriously? Would live chat be able to redesign the app and make it work. Just beyond belief that Three UK think that’s an appropriate response at all!! 😱🤦🏻‍♂️

Developer Response ,

That's a bit harsh. We'd suggest that you delete then reinstall the app. If that doesn't help, please chat with us in the app or online at - Kinjal

Very Disappointing

This is the first time I have looked at 3 as my mobile service provider purely in that the package suited. So well done on that score. However having spent nearly an hour trying to download the app then getting it to work I wished I hadn’t bothered. Firstly the email verification didn’t work, it just got me into a loop. Looked at the feedback which on many occasions replies suggested re installing the app . Tried that twice to no avail. Now I think I’m pretty savvy with technology (well I used to). I eventually reverted to doing it on the web which wasn’t a pain free experience either but at least i managed to get some credit on the account.

Still haven’t got the app to work. Any suggestions other than reinstall?

Developer Response ,

We're sorry to hear that. We’d suggest, please chat with us online at We'll do all we can to help get this sorted out - Reece
