The SMS indicates that it is connected.

The solution to the problem that the phone can't come in and only SMS prompts is to reinstall the phone card into the card slot.

The calling card is responsible for connecting the operator's network, so that we can make phone calls, send text messages and surf the Internet. When the mobile phone shows that the phone can't be connected and can only be prompted by SMS, there is often a problem in the connection between the calling card and the mobile phone. There are many reasons for this problem, such as unstable phone card insertion, dirty card slot, mobile phone software problems and so on.

The first step to solve this problem is to confirm whether the calling card has been inserted into the calling card slot. Sometimes, when we accidentally touch or drop the phone, the calling card may pop up or loosen. Please fully insert the calling card into the card slot to ensure good contact between the card slots, so as to avoid normal calls due to poor contact.

If the phone card has been inserted into the phone card slot, the problem still exists, and you can try cleaning the card slot. The card slot may be blocked by dust, dirt and other sundries, resulting in unstable connection. At this point, you can gently clean the debris in the card slot with a sharp and clean needle or cotton swab, and dry the card slot with a clean hair dryer to ensure that there is no water left.

The reason why the phone can't be connected

1 network problem

Nowadays, most telephones communicate through the network. Once there is a network problem, the phone will not work properly. Network problems may be caused by poor signal, network failure or network congestion. If we make a phone call in a place where the signal is bad, or during the network failure, we may encounter a situation where we can't get in.

2. The telephone number is not entered correctly.

Sometimes, because we are in a hurry or for other reasons, we may enter the wrong phone number, so that the phone cannot be connected. When you enter the phone number, you must check it carefully to make sure there are no mistakes, so as not to waste time and energy.

3. The other party's mobile phone is turned off or stopped.

Naturally, the phone could not be successfully connected. Similarly, if there is no signal coverage at the other party's place, then the phone can't get through. In this case, we can only wait for the other party to open the phone or enter the service area, and then call again later.
