Solve the problem of 'No SIM card' displayed on Apple iPhone 15

The iPhone signal problem has been criticized by users. In order to solve the iPhone signal problem, Apple this year’s iPhone 15 baseband was upgraded from the Qualcomm X65 of the iPhone 14 to X70.

According to Qualcomm official introduction, X70 supports all 5G commercial frequency bands from 600MHz to 41GHz, with a peak downlink rate of 10Gbps and an uplink rate of 3.5Gbps. Compared with iPhone 14 , the 5G speed of iPhone 15 equipped with Qualcomm X70 baseband has increased by 24%.

I thought that after the iPhone 15 used the Qualcomm X70 baseband, the signal would always be online, but the result was still unsatisfactory: the iPhone 15 would still appear "No SIM card" , "SIM card not installed" or "Searching the network" and other warnings.

Apple iPhone 15 displays “No SIM card”, “No SIM card installed” or “ What should I do if I get a warning such as "Searching the web"?

If the above prompt appears on Apple iPhone 15, you can try to solve it by referring to the following methods:

3: Then go to "Settings" → "General" → "About This Mac" to check whether the operator requires an update. If an update is required, it will be charged. Go to the update prompt, update it and see if it can be used normally.

Four: If it still doesn’t work, try taking out the SIM card and gently wiping the metal surface, then reinsert the SIM card, making sure that the SIM card tray is fully closed and not loose. .
