So I played my normal iCloud backup a (This works really great and makes virtually no work. Everything transmitted and you've got your phone back to the way it was) and realized that the SMS delivery was not working.
The reason for this seems the provider asked (in my case, Vodafone) available new Nano SIM to be, because this is probably quasi initially identified to the contract as a second card.
Whatever helps Vodafone following code, which you simply eingebt in number field of your phone set:
* 133 #
The SMS sending and receiving at least has to work again in connection with me. With this code, the Nano Sim will probably declared new main map.
At Telekom customers with this phenomenon, incidentally, this Code is intended to help:
* 222 #
Lack Telekom contract I can not verify and confirm that but. Just try it.
Did it help you? Short feedback would be great. Even and especially for the other readers.
