Why can't this mobile phone receive short messages?

Reasons for not receiving SMS+Solutions (1) Users often ask that SMS can't be received on their mobile phones, or SMS will be delayed. In fact, mobile phones can't receive information. Generally speaking, it has little to do with their own hardware, and most of them should be caused by software. We have answered these questions in time before, but most of them are scattered. So on March 15, we also summarized some corresponding reasons for your reference. If users encounter such problems again, they might as well check them step by step as a complete set of problems until they are solved. Reason 1: The SMS center number of mobile phone is incorrect ★★★★★★★ Because some models involve customized versions, parallel imports and port differences, the SMS center numbers of these models are generally not mainland SMS center numbers, and licensed mobile phones will become factory settings after refreshing or restoring 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 regions of the country have different carrier networks, the corresponding SMS center numbers are also 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+8612500 Shanghai Mobile +86 138002 10500 Shanghai Unicom +86660. 5438+0380075500 Shenzhen Unicom +86 130 1088500 Tianjin Mobile +86 13800220500 Tianjin Unicom+861305438 Chongqing. 1083 1500 note: 1, except for municipalities directly under the central government, the number of China Unicom SMS centers is one in one province, and there is no difference at the municipal level. 2. The numbers of the telecom CDMA short message center are all built-in, and generally cannot be changed and set. 2. This phenomenon caused by software conflict 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. It is best not to install too much software related to information such as number, place of origin, call, contact person, etc. 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 signal in your place is unstable, and the network settings are 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), some closed places (elevators, subways, underground garages, toilets) will also appear, which may also cause short messages to be temporarily unavailable or delayed. 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. Page 2: Reasons for not receiving SMS+Solutions (2) Reason 4: Inbox overflows, and the machine memory is insufficient ★★★★★★★★ Many people have the habit of saving information, 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, which is especially common in 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 when they 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 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 blacklist function. You can blacklist some numbers that often send spam messages or people who are not good to you, so that you won't receive messages and calls from these numbers. 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 6: 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. Unless there is obvious falling or bumping in the subsequent process, the information function may also be unusable. 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.
