How to Fix Cell C Network Problems with SIM Card Not Working or Registered

It’s not unusual to face network challenges irrespective of your network provider. For Cell C customers, some of the common challenges may include SIM cards not working properly or not being registered. Thankfully, there are things you can do to salvage the situation. To learn how to fix a Cell C SIM card not working and a couple of other things you need to know about the Cell C network, ensure that you stick to this article till the end.

Reason Why Your Cell C SIM Card Not Working

There are a variety of reasons why you may notice that your SIM card is no longer working, and it’s not all the time that the fault is from Cell C. Sometimes, it can be something you can resolve. Here are some of these reasons and how to troubleshoot:

Worn Out SIM Card’s Copperplate

The copperplate of your SIM is supposed to be shiny gold in color. However, over the years, it usually becomes black and worn out. As your SIM card wears out, you may start to notice that your SIM is no longer working. However, you don’t have to worry about this because it takes years for your SIM to get worn out.

If this happens, what you need to do is to visit the closest Cell C outlet. Most likely, you will be advised to buy a new SIM card. Thankfully, it is now possible to retain your mobile number; all you need to do is a SIM swap. While visiting the outlet, consider going with your SIM, ID, and proof of address in case you need to buy and RICA a new SIM.

Inserting your SIM wrongly

After inserting your SIM card, if you realize it’s not working, it is possible you did not insert your SIM properly. Consider removing the SIM and inserting it correctly. Usually, SIM slots are built so that they guide you on how to insert the SIM.

Dirty SIM and SIM tray

Another reason your SIM card may not be working is that either your SIM card or SIM tray is dirty. Both dust and liquid can stop your SIM from working, and while cleaning the SIM tray, you may want to be careful to avoid breaking it.

Deactivated SIM Card

If your SIM card has been deactivated by Cell C, you will notice it is no longer working. This can happen if you fail to fund your SIM or use it within 90 days. To avoid this, ensure that you keep your SIM card active.

Other things you can do when your Cell C SIM card is not working include:

  • Toggling flight mood
  • Insert your SIM card on a new phone to check if it’s still working
  • Restart your phone

Ensure that you have checked all of the above before raising an alarm that your Cell C SIM card is not working. While Cell C may be able to fix network problems from their end, it may not be able to fix problems that emanate from your phone.
