As in the data there was the sim id too. A new sim (and the blocking of the old one) should stop the use of a cloned old sim to break into accounts protected with 2FA autentication based on Ho numbers on the old (and cloned old) sim.
That leaves you open to all the other attacks based on all the other data they leaked and then you have to consider if you trust Ho enough to still stay with them even with a new sim...

In the data leaked there is the internal id of the sim, something that can be used to clone the sim itself and that with some fishing and/or social engineering call lead to break 2FA autentication schemes.
That is why, beside your own trust for Ho, a sim swap, can mitigate the issue as the new sim will have a new id and after that your 2FAs should be safe.

The Music of the Primes: Searching to Solve the Greatest Mystery in Mathematics by Marcus Du Sautoy.

We can say that this book is quite similar to Fermat Last Theorem by Singh the main differences are:
- It is about Riemann hypothesis and not Fermat Theorem
- It is not solved (yet):-)

I read it at least a couple time (and i just read once the Singh one), i really loved it, the format of the book is almost a collection of the biographies of the mathematicians that studied it but the thing that hook me is the feeling of the almost "need" of those scientist to work with it, not to mention the vastness of the implication it has (from pure math to physics to cryptology).
It is really readable even without great math knowledge, as there is almost no equation there.
