The pdp authentication is used to ensure that your mobile device is recognized in the network.

This is what you can do if there is the pdp error.

Here, too, it does not matter whether they are under contract with E-Plus or with another provider, you should first check the following:

  • Can you phone or SMS to write? So if you can do that, you have a connection to the telephone network.
  • Try to get a SIM card from another network and use it to log into the network. If this works, then the problem with the pdp authentication is not with your device, but clearly with the network provider.
  • As a rule, a failed pdp authentication is always due to the network provider, i.e. if you are with E-Plus, E-Plus. The tests are important because the network providers are happy to pass the problem on to the device and yours Complaint like a ping-pong ball going back and forth between E-Plus and the provider of the mobile device could.

  2. If the restart did not suffice, remove the SIM card. Select the settings menu and then "General" and "Reset".
  3. Then choose Network Settings and turn off the iPhone. Now insert the SIM card again.
  4. Turn the device on again. When the iPhone is up, go back to the settings menu, then to "General". Call up "Mobile data network" and enter "internet.eplus.de" under APN.

How to complain to E-Plus

  • If there is a shop nearby, you should report the problem there, otherwise call the hotline. Say that it cannot be the device because a SIM card from another provider is not a problem.
  • Insist that it must be a network error with E-Plus and that the LDAP must probably be cleaned up. A technician should check this and carry it out if necessary.

If the measures described do not work, it just has to be due to the network and you have no access to it. So only E-Plus can help you if the pdp authentication never fails and the measures mentioned are of no use.
