A small hint on what Monzo Mobile might look like

I got a survey request from Monzo this morning regarding Monzo Mobile – and one of the questions was possibly illuminating. It showed some example price plans and asked my opinion.
I took a screenshot of it:

Treat it simply as a thought experiment as the actual pricing and product mix is likely to be quite different.
What's your view?
If, for a moment, you pretend these are actually real, are you switching?
The £25 unlimited option feels steep. It feels like they've taken an existing off-the-shelf price plan and added £5 to it.
And then £10/month feels much worse than you'd ordinarily get from, say, Giffgaff, or even a standard o2 pay-as-you-go option, simply because it expressly excludes roaming, which, even as a bog-standard prepay user, you tend to get from most operators.
And then, the £15 one... again, feels a bit mismatched.
But.
I would imagine that's the point in the research. To see where the hot buttons are for Monzo customers and to get their perspectives on how they would potentially purchase.
I went for the £25 one... but that's because I'm already a Monzo Max customer and my instinct is to go for the best. Well. No. Actually, if I reflect for a few moments, it's because I expect to have decent roaming. 10GB roaming (£15/month) felt weak... which pushed me to the £25 option.
I wonder how this will differ from the actual price plan options?
I wonder if they'll go for three.
I wonder if they'll hook the price plans into the existing 'subscriber plans' that they already offer?
I would expect the entire experience to be point-and-click on their app. I have every confidence that they'll make that very smooth.
I still would like to hear some of Monzo's super-genius cyber and data security experts opine on the risks of having your mobile plan operated by your bank. How much more risky is this, if your phone is stolen, for example?
Indeed, I'm not sure the phone-and-bank combination has been given much consideration in the wider marketplace. It has always been separate, right?
Even today, though, your mobile number is still used (rightly or wrongly!) to evidence you are you. It's often one of the multi-factors used by a lot of people.
Perhaps, I'm worrying a little too much.
That being said, wherever possible, I have always sought to remove SMS or the phone number as a pathway for identify verification from any service. Sadly, too often, it's the only default.
Anyway.
It's exciting to think about Monzo's upcoming price plans!
