If someone has never received the error message "Mobile data network could not be activated" on their iPhone, I would like to congratulate them warmly. This message keeps popping up for me - and it doesn't matter whether I had Blau.de or AldiTalk as the provider. But now I would like to help the AldiTalk users, because I have the whole thing for Blau.de already posted once. AldiTalk can also be found under the label "MedionMobile" and that runs just like blue on the e-Plus network - for information only.
If you order your nano SIM for the iPhone 5 from AldiTalk, you will also receive an A4 sheet of paper with the necessary settings for the mobile data network. You can usually find this information here:
For beginners, I would like to briefly explain where you have to enter this data on the Apple iPhone so that you can access the Internet while on the move.
First you go to the home screen and look for the "Settings" app, which you can use to configure all things on the iPhone. After clicking on it, you will see "Mobile Network" as the fourth point. You click on this again and then see an entry "Mobile data" at the top, which is provided with a slider that you have to set to "on", i.e. to green.
If you scroll down a bit on the screen, a menu item "Mobile data network" appears. A click on it leads us to the page on which we can enter the settings shown above. Only the first section "Mobile data" is important on this screen, which asks for these three points:
If these three fields are filled, you can go back with the home button and, with the WLAN switched off, test whether you can use the mobile data network.
If you want to use the iPhone as a personal hotspot, you have to scroll down to the bottom of the last screen and make the same entries under "Personal hotspot" as under "Mobile data".
