New eSIM subscription - insane costs, why is bundle not working?

Hi! Yes, the number transfer was requested and I started using Simyo with the temporary phone number eSIM was coming with, before the number transfer was completed.

That way you wouldn't pay double for your subscription

Well, instead of paying for double subscription fee, Simyo now want’s me pay >€400 for a few weeks of use. Without a single notification about this crazy behavior!

Why I was not completely suspended from network use until the subscription bundle becomes “active”?

I was using many mobile providers in many countries. This is the first time I see the mobile plan that is not “active” since you the beginning of use.

And those out-of-bundle costs are unreasonable. Why Simyo is not blocking the SIM card when it reaches much lower spendings value? €400 is the 3+ years of spendings with my current (but not “active”!) subscription - why this is not suspicious enough to block the SIM card much earlier?

That's indeed what I expected happened.

Simyo expects you to use your old subscription until your previous provider kicks you of their network to transfer your number. I believe most customers seem to do that as I rarely see issues such as yours.

Given your bundles were not active yet, there would not be a 80% and 100% data bundle usage warning. The only thing you can run into then is “Hoogverbruik” or "High usage”, which blocks any connection exceeding 100 euro/day or 250 euro/days of (out-of-bundle) costs. Sadly even this protection is not as good as it monitors usage with a delay, which allows you to exceed this limit if there is an amount of usage in a short time.
 

That's not how Simyo works. As I said before: Simyo expects you to use your old subscription until your previous provider kicks you of the network to transfer your number. I believe that is most customers seem to do.

I believe Simyo even warns in the welcome emails about this, but do not point me on that. I have been customer for some time and things may have changed!

Yes, the out-of-bundle costs for data are pretty outrageous. €0,15/MB, which is 300 times the costs of the MBs in your bundle.

As customers we have asked plenty of times to offer some sort of protection against those huge out-of-bundle data costs. Sadly Simyo does not care about that. If you have android, make sure to set up the data cap feature of it. If you have iOS, better never exceed your subscription!

I just felt in the same trap. That's an absurd that they do this. In the sake of "don't charge you for a second plan while the number is not transfered" they charge you much, much more. In my case , more than the expected for the whole year (€150).
