How to solve SIM card errors

We’ve all been there when setting up a new phone and things don’t always go smooth sailing. Usually, errors during setup can be an easy fix as it is generally something small, such as the wrong button pressed when installing. For SIM card errors, this can be particularly frustrating as it hinders the use of making calls and sending texts. So, what can we do to fix this? In this article we have highlighted our advice to resolve SIM card errors.

Is the SIM card in the correct direction?

One of the first things to check is ensuring the SIM card is facing the right direction. SIM cards are quite small so it is quite easy to accidentally position it the right away. Try removing it, and ensuring it matches perfectly with the SIM card slot with the metallic contacts facing the correct side.. Sometimes it’s beneficial to check the user manual to see if there’s a particular method which will ensure it sits correctly.

Has the SIM tray been fully inserted?

Some phones take the SIM card in a tray in the side, whilst others are inserted under the battery at the back. If using a SIM tray, ensure the tray has been fully pushed back in. If it is slightly poking out, this may mean that the SIM reader cannot read the card properly. To rectify this, push the tray in until it clicks into place.

Is your SIM activated?

If it is a new SIM being inserted into the phone, you may need to contact the network provider directly to ensure the SIM has been activated. You can simply do this by giving them a call or using an online service.

Is your phone unlocked or locked to a network?

Another point to check if whether or not the phone is already locked to a network. Some phones come unlocked, whilst others are ready to work with a particular network. If it is locked, you may need to contact the existing network provider to get an unlock code to use it with another SIM. Or, you will need to use a SIM for the network that the phone is locked to.

Can you try rebooting the phone?

Sometimes it is worth rebooting the phone. This is recommend in case the phone is struggling to read the SIM. By rebooting the phone, it can refresh the reader and may resolve the issue.

Reset your carrier and network settings

It might be worth updating your carrier settings if available. Depending on the phone being used, it can be found under your General Settings and titled ‘Carrier Settings’. If available, the phone should prompt for an update which you can tap to update. This is useful if there have been any updates with your network provider.

Similarly, under the same General Settings menu, you are likely to find an option for network settings. We would recommend resetting the network settings and trying the SIM card again as this may resolve the issue.

Cross-test the SIM Cards

If all fails, the next best step is cross-testing the SIM card. This means trying the SIM card in another phone, or trying another SIM card in this phone. This helps to identify where the issue is coming from. If another SIM is working fine, it may be a SIM-related issue with the card that’s not working so the next step would be to speak to the network provider.
