If you keep getting a "No SIM," "Insert SIM Card to Continue," or "No SIM Available" error message on your phone, even when you have a SIM card inserted, it may stop you from receiving and sending texts and calls. This wikiHow article will give you some possible causes and troubleshooting options to fix your phone.
Why Your Phone Says "No SIM": Common Reasons
If your phone can’t read your SIM card, the card might be inserted incorrectly or the tray might be loose, dirty, or damaged. The card itself might also be worn out. If there’s nothing physically wrong with your SIM, make sure your carrier settings are correct.
