SIM not set up: You can do that

If you receive the message "SIM card not provided" or "SIM not set up" on your smartphone, you cannot use your cell phone for the time being. In this guide, we will show you how to solve the problem.

SIM card not provided: common errors and solutions

If "SIM card not provided" appears on the smartphone, you should first check whether the SIM card is already activated. Before using it for the first time, you usually have to activate the card online or by phone from the mobile phone provider. So take a look at the SIM card documents. Sometimes it can take a few hours after activation for the card to be really ready for use.

SIM card not set up: restart can help

A restart of the smartphone also offers quick help. This not only clears any problems in the cache, it also re-establishes the connection between the SIM and the radio mast.

Broken SIM card?

You should also take a closer look at the SIM card. Turn off the smartphone, remove the SIM card and wipe the contact with a dry cloth. If the SIM card is new, you can usually rule out a defect. Blow as dry as possible into the SIM slot of the smartphone to remove dust or other foreign objects.

Adjust settings for the network operator

If you have made a fundamental change to the system through a jailbreak or a custom ROM, this may be the cause. In this case, you should check the network operator settings manually. You can find instructions for iOS and Android here.

At best, the problem is not yours. The provider's servers may be temporarily unavailable. At AlleSt Stör.de you can check whether there is a fault for the Telekom, O2 or Vodafone servers. Then try again later.

Last aid: customer service

If you cannot solve the provisioning problem with the previous tips, the SIM card is probably blocked. Therefore, please contact your provider for further support: Telekom customer service, o2 customer service & Vodafone customer service.
