 A poor cellphone network

Broken or faulty SIM card

If your SIM card is faulty, it would definitely be impossible for your smartphone to connect to a mobile network. It is necessary to insert the SIM card into another phone in order to determine whether you are having problematic SIM card symptoms or your smartphone is broken. According to Boost Mobile, a dirty SIM card may hinder your phone from reading the encoded data and establishing a network connection. Rub a soft eraser or the tip of a Gold Guard pen over the integrated chip on a SIM card to clean it. Clean the card, then re-insert it into your smartphone to see if your device can now access the contents of the chip.

Your phone is having problems

Another potential source of the issue is a broken smartphone. You’ll need access to another smartphone that you know is functioning properly to determine whether your smartphone is the cause of your connectivity problems. Bring the SIM card to your carrier’s shop, so they can use one of their test SIM cards if you can’t find another phone to test it on. Your smartphone should be turned off and then the SIM card should be removed from your device. Use a different smartphone to insert the card. Your SIM card is the fault for your problems if the second phone is also unable to read the card, either because it is unclean or damaged.

Location issues

The SIM card enables voice conversations and cellular data access, however, problems with the cellular network may only be tied to your current geographic location. For instance, your carrier network might not be available where you go, so you’ll need to choose a different network provider to keep your phone calls and cellular data active. Others, on the other hand, opt to disable automatic updates, in which case the device does not alert them to a change in the carrier network’s accessibility. Therefore, you can see the error message “cellular network not available for voice calls” and will need to choose a different operator to place voice calls.

Set automatic for network selection

 Your phone’s network selection may occasionally be incorrect owing to bugs or strange occurrences. This indicates that even though you, for instance, have an AT&T sim, your selection is Verizon. Your carrier’s services can once again be accessed by switching your network option to automatic. This is the best fix.
