@AlsoKnownAs_AA @SpaceX Depends if you buy your phone via a carrier or direct from Apple, Google, Samsung (or maybe Starlink in future)

[Dean Bubley @disruptivedean]

People opining on spectrum, @SpaceX 800MHz & D2D are missing an important element of the discussion

Starlink doesn’t need people to churn from terrestrial mobile. Or the same capacity as MNOs

Dual SIM, Dual Standby

Partial churn

A % of value, not 100%

* DSDA (dual active) is rarer but even more applicable here

@ScubertDubert70 @peterlindmark Thanks for the screenshot. I’ll be using it as a reverse testimonial

[Dean Bubley @disruptivedean]

@ScubertDubert70 @peterlindmark I literally advise governments, companies and investors on spectrum policy and indoor wireless

[Dean Bubley @disruptivedean]

@bdistel @elonmusk @realDonaldTrump Neither is entirely right

It doesn’t replace cell towers

It makes some of them - and the networks - less valuable

It’s part of a more complex blend for D2D, that hinges on phones with 2+ eSIMs

Both probably know this, but cannot say it

https://t.co/78jctUOW67

[Dean Bubley @disruptivedean]

@ScubertDubert70 @peterlindmark I understand both

And I also understand dual SIM dual standby phones. And Wi-Fi

And strategy

@peterlindmark You’re missing the point

@aaronburnett It’s not about “alternatives”

It’s about what is complementary

[Dean Bubley @disruptivedean]

@tomfgoodwin Bit different for B2B sites I think

[Dean Bubley @disruptivedean]

@elonmusk @aakashgupta Not quite right

It doesn’t replace cell towers

It makes some of them - and the networks - less valuable

It’s part of a more complex blend for D2D, that hinges on phones with 2+ eSIMs

@mikebutcher Bizarre

Nuclear energy is an ethical positive for Mistral

[Dean Bubley @disruptivedean]

@dan_tmt Depends if it’s happy with partial competition & substitution

@mikeddano @anshelsag @JohnSaw In a world where the average user has 1.5-2.0 active SIMs/eSIMs, it doesn’t matter so much

https://t.co/78jctUPtVF

[Dean Bubley @disruptivedean]

@peter_adderton @SpaceX The risk is that ultimately the carriers become the “complement” even if they carry more traffic

After all, WiFi carries even more, yet it gets denigrated as “offload”

In a world where the average user has 1.5-2.0 active SIMs/eSIMs, control is tough

Very interesting to see the SpaceX deal with Grain Management, LLC for 800MHz spectrum in the US. Firstly, it's very gratifying to see the indoor connectivity limitations of D2D being taken seriously. I think there's a possible narrative flip....

UK regulator @Ofcom recently conducted a consultation into the future of the 2GHz MSS satellite spectrum band, as @EchoStar and @viasat licenses expire next year.

I was one of the respondents, suggesting something very different to other submissions.

@swardley He’s absolutely right

AFAIK there is absolutely no evidence or precedent for wealth taxes leading to economic growth

Wealth isn’t “distributed” so logically it cannot be “redistributed”.

It’s a synonym for theft

[Dean Bubley @disruptivedean]

An unspoken downside of loyalty schemes is the risk they alienate non-customers vs encourage existing customers to buy more.

For example, @Tesco supermarkets offer huge discounts for Clubcard holders. But by making them obvious, I see how much I’m being ripped off

So I leave.
