What's the matter that the telecom version of Cool Phone can't accept SMS?

Reason 1: The SMS center number is incorrect.

Because some models involve customized versions, parallel imports and port differences, the SMS center numbers of these models are generally not from Chinese mainland, and licensed mobile phones will become factory settings after refreshing or restoring their factory settings, which may lead to mismatched SMS center numbers. Because there are different operators in different parts of the country, the number of SMS center in each area is different, which further causes the confusion of SMS center numbers. The user's own setting error may also lead to incorrect SMS center number, so the main reason why the mobile phone can't send and receive SMS normally is mostly related to the wrong setting of SMS center number.

Solution:

Because different parts of the country and different carrier networks, the corresponding SMS center numbers are different. If it is just a list, it will be a huge amount of data. In addition, for users, it is not only tedious to find the number of SMS center on the Internet, but also the version and year of many materials will cause inaccurate information. Here we suggest that you can go to the business hall of the local operator to find out. Generally, someone will help you find the most correct SMS center number and set it up. Because the numbers of SMS centers are different all over the country, here are only the numbers of several major cities.

Beijing Mobile +86 13800 100500? Beijing Unicom+8613010112500

Shanghai Mobile +86 138002 10500? Shanghai Unicom+8613010314500

Shenzhen Mobile +86 13800755500? Shenzhen Unicom +86 130 10888500

Tianjin Mobile +86 13800220500? Tianjin Unicom+8613010130500

Chongqing Mobile +86 13800230500? Chongqing Unicom+8613010831500

Note: 1, except for municipalities directly under the central government, the number of Unicom SMS centers is one in a province, and there is no difference at the municipal level.

2. The number of SMS center of CDMA model is built-in, and generally cannot be changed and set.

Reason 2: Software conflict.

This phenomenon is not difficult to understand. Generally speaking, we will advise you to install your own practical software in moderation. Because installing a large number of software will not only slow down the running speed of the fuselage, but also cause conflicts between software until there is a white screen crash or crash. Software such as security guards and attribution inquiry may change the number of SMS center accordingly, or some firewall software may block relevant information, thus causing the phenomenon that SMS cannot be received.

Solution:

This phenomenon requires you to find the software related to contacts in time, and it is best not to install too many software related to numbers, places of origin, calls, contacts and other information. Because this may cause conflicts between software, and some software firewalls or protection functions will filter out some sent information and calls accordingly. If you can't receive SMS because of software conflict, delete the software that caused the conflict in time. If you can't uninstall, you can choose to restore the factory settings when the backup is good.

Reason 3: The local signal is unstable and the network setting is incorrect.

If the signal in your place is unstable, the network is temporarily missing, or affected by other aspects (magnetic field, tunnel, or other network blind areas), this situation will also occur in some closed places (elevators, subways, underground garages, toilets), which may also lead to the temporary unavailability or delay of SMS. In another case, due to the network settings, if the access point is not set correctly, the multimedia message cannot be received. Most of users' questions focus on Android models. Although there are many settings on the Internet, most of them still can't be used normally. Here we introduce you to a relatively simple and very practical method.

Solution:

Mobile phone settings-wireless and network settings-mobile network-access point name. After entering the name of the access point, if it is empty, you can click the menu button and select New APN, and then a new interface will appear. Fill in the name (name) and the APN option is "cmnet", regardless of other options, and then click the menu to select Save. After all the above steps are completed, you will find that there is an access point of cmnet in the access point. Just select it, and then you will find "E" and two small arrows up and down in the notification bar, indicating that the network connection has been set up successfully.

Reason 4: Inbox overflowed, and the body memory was insufficient.

Many people have the habit of keeping messages, but if the number of messages stored in your mobile phone mailbox is not large enough, the inbox will overflow, resulting in the inability to receive new messages normally, especially the MMS inbox. On the other hand, the lack of memory in the fuselage will also lead to unacceptable information. Similarly, if too many third-party applications are installed, the storage space of mobile phones will be insufficient, especially those non-intelligent models that don't have much space.

Solution:

Many users don't understand or know this phenomenon, especially those who can't receive MMS. For example, a certain model has only 60M memory, and you receive 6M-sized 10 multimedia messages. At this time, if you return to 1 1, you will be prompted that the inbox overflows because there is not enough space to get new information. Many users also ask that there is a message icon flashing on the top of the mobile phone, and I don't know what it means. This is to remind you to clear your inbox in time. The same is true for ordinary text messages. In addition, many users also have the habit of retaining information. Many a mickle makes a mickle, which will inevitably lead to the flood of information and make it impossible to receive new information. So users in this situation need to clean up their mailboxes in time.

Reason 5: The mobile phone blacklist SMS phone restriction function is turned on.

This kind of function is common in mobile phones. Sometimes or in some cases, the mobile phone blacklist is used involuntarily, and the number of some contacts is added, so the information of the corresponding contacts will not be received. Although this situation is unlikely to happen, it may be common for some unsuspecting users.

Solution:

Generally, mobile phones will have a blacklist function. You can add some numbers that often send spam messages or people who are unfavorable to you to the blacklist, so that you won't receive information and calls from this number again. Many users will tinker with their new mobile phones for a period of time, and may add someone to the blacklist without being familiar with it, thus causing the phenomenon that short messages cannot be received. If the above situation does not apply to you, then you should check whether the blacklist function of your mobile phone is turned on.

Reason six: the quality problem of the mobile phone itself.

This phenomenon is unlikely to happen. Generally speaking, users will choose to try out the information function when buying a mobile phone, and may not use the information function unless there is an obvious fall or bump in the subsequent process. For example, the phenomenon that some short messages cannot be received should account for a small part of the relationship with the mobile phone itself, and the other part should have a greater relationship with the operator network. Users don't have to worry about this phenomenon, because similar delays don't happen often and need to wait patiently.
