Came across the following, thought folks might be interested, as everyone has mobile these days, I have signed up myself.
Honest Mobile, a new mobile operator starting up soon - “building a better mobile network together”
Feel free to use my referral link:
It’s quite expensive
Looks like they’ll be using more than one network somehow
Honest uses more masts than any single UK mobile network.
They are promising EU roaming forever, and as far as I know, the only U.K. network to do this is Three 
They seem to be advertising the Ofcom mandated text-to-switch service as a feature of themselves. They’ve even stuck their own marketing name on it, “QuickSwitch”. 
It’s not a good start on the honesty front. 
If you go to their page for business users (https://business.honestmobile.co.uk/), it has the EE and O2 logos. Could be a using both of these providers?
Also the price might confirm this kind of setup, as if you look up any multi network setup they usually have quite expensive plans.
They have updated the faqs - it looks to be Three as their main provider and then EE and O2 as auxiliary suppliers. You need a Bolton to use them though.
Here’s one:
Wait. What? Not that sort?
Oh, a bolt-on…
I’m presuming that comes at a cost so the main benefit they’re marketing— the best network coverage—isn’t included in the standard product? 
Honestly. 
For example during peak hours I can get 80mbps on EE but with honest mobile speed is capped at 20mbps on EE .
During non peak hours I am getting the same speed for both 3 on my home broadband using 3 and using the honest mobile .
The beauty is you have more network option. Some area that I am working has better O2 coverage then EE or 3 and vice versa.
It’s fairly a new company and I am still giving them constructive feedback.
As mast sharing agreements grow especially in rural areas I see less of a value for multi carrier sims.
EE and three share masts , and O2 and Vodafone also do , so with eSims and dual SIM phones common now you realistically just need a main sim on one network and a backup sim from one of the other group.
They seem like nice folks with good intentions.
Joined and provided some beta feedback and they were very nice and responsive.
Progress in the last few months is pretty quick too.
But, yeh, price is not super competitive. Some they need to do this to grow.
And the Three signal where my family live, where I live and where I work is horrible!
You can but the bolt on for the signal share, but as mobile devices don’t actively check which provider has the best signal, you have to manually change to another signal to avoid Three with their 1 bar service.
I’ll stick around. I’m kinda interested in how they will progress
Same here. They are very responsive in replying back. I have Been giving constructive feedback in the last one week.
They are using 3 as their main network and you can go between O2 and EE whenever you want. If you don’t know man you any then it will just move you to another network if you just happen to go out of coverage for over 30 seconds on their home network. In my experience it will go and find an EE signal first and then and O2 signal. As of next yeah the network but also let you access Vodafone and 5G all phone networks. I have a business plan with them and I get unlimited data for little over £40 a month I’m extremely happy with them
Just signed up to Honest, been meaning to switch providers 
I am not much of a fan of “buy us because we’re sustainable, we do carbon offsets” when i could buy a cheaper product, donate for the carbon offset myself and get the tax benefits 
however! I think for the price point it is competitive to some places like Giffgaff, and I get a 10% discount from being referred 
There’s no contract either, so if I can find a better option I’ll move
