Invalid MMI or communication problems
When you’re trying to contactthe operator’s number using a smart mobile phone, and then PopUp will find that the problem with writing connections or MMI codes is incorrect. Of course, it’s very confusing. Especially if you really need specific information from your private operator at that time. Of course, it can be done. There is an error in the code entered for specific reasons.
Of course, as a user, you really need to understandhow mme code can be considered inappropriate. So in fact, it can actually be calmer and not confused, because it can then be solved independently, and then try to contact the employee according to their needs. Although you need to take some steps first.
The existence of this selected step cannot be performed permanently when it attempts to reduce the factors of invalid MMI problems or problems . So we really need to wait a few seconds to see if the operator can be contacted later. You don’t have to worry immediately that your smart phone is corrupted because it’s connected to the operator’s network.
So when he understands it well and waits for him to be calm. If it’s not resolved when you try again, you can start trying to take some steps. It can actually be done as a solution to an error in the MMI code. You don’t need to come to the service location, this situation still dominates yourself.
Understand your phone’s MMI code error
The theme of a man’s car for MMA stops in the form of code. This code is a special service created for you to access various features on your phone. Special code includes multiple components of symbols as well as numbers. Of course, it will be easier when you need to use features. special for their private operators.
Using this special code is when you need information on the Internet or trust section, as well as IMEI, and other requirements. However, there are still many possibilities for incorrect mmi communication problems or codes to appear and are also very annoying because they prevent the process when you need to check the information specified on your network according to their personal needs.
Various items cause errors in mixing these symbol numbers, for example, because network settings are happening incorrectly and there may still be several unimportant files stored in the phone memory. The code error occurs because if a temporary insect appears on the phone, and because there is no support for the operator’s sign, it is decreasing.
So in fact, having an incorrect phone call problem or MMI code is not serious and even requires special treatment. Users can actually take alternative steps based on these appropriate reasons to make it easier later to correct errors.
Practical advice to reduce private code errors
Most basic solutions are actually very easy to use as solutions if there is a related problem or invalid MMA code. The cause may be an ant on your marker network, so the solution is to restart the phone, then wait a few seconds before trying to contact the server. This step will actually help repair if there are insects on the phone.
The next replacement solution can be easier for you to try to put the plan mode on your smart phone, after waiting some time for the normal signal to return. This is a very helpful solution to correct your signal again and quickly captured appropriately by the phone.
When you find an invalid MMI connection or code problem, it can be because a less important store is actually stored in memory. Keeping documents is less important for your memory to definitely end up interfering with your performance. So it’s important that you try to use it to check the file administrator section and start deleting invaluable documents from memory.
Clearing a variety of unimportant caches and files on your phone will make memory available for other purposes. In the Settings section, you can certainly easily find the storage section that is actually being cleaned up. Doing it properly will help keep smart mobile performance and good memory.
Insert a specific mark on the User Number Mix
If the previous quick trick is really not yet able to definitely change the connection problem or the MMI code is invalid and there is still a problem, try taking further steps. Inserting a special bookmark into the operator code when you contact the operator can be replaced to fix the error .
You can insert + bookmarks at the beginning of the typed code. For example, the code you need is to contact *123# then try writing *+123#. Get the + symbol how to hold the zero number longer. This style can sometimes succeed in overcoming an incorrect code error problem on your phone.
Another specific sign can also be used as a comma. But unlike the previous letter, you must insert this coma letter at the end of the code. For example, writing *123,#. The way to get commas in the request is to hold the * button longer.
Inserting this character is actually a step that is rarely known or performed. If you have done everything else, but it has not succeeded, putting the character will surely be very helpful. But note and check again for connection problems or invalid MMI codes you are using correctly.
The possibility of an error reading the custom code in the given command will also be found. Therefore, an important step can be taken as a solution by giving these custom characters used to try to implement it, for example, there is a connection problem or invalid MMI code is still ongoing.
How advanced solutions change the signal
A network on smart phones with a large signal that is widely used today is 4G LTE. However, this signal also often causes errors such as communication problems or incorrect MMI codes. This barrier exists because of the lack of support for this sign when it needs to connect as well as normal short messages. Of course, the network’s priority is because it is the main focus on the internet.
So in overcoming this problem, you can try to temporarily change the 3G signal from using 4G. Of course, only by solving the needs of a short phone message to make the network better. This reduces the occurrence of problems or errors in the specific code while connecting to the operator.
To change you can go to the Phone Settings section and then take the mobile network option. In this option, there is an option to install the network used on your phone. It will only remain to change from 4G to 2G/3G, then save settings and try creating an user connection as the beginning.
This way your phone network will be stronger and there will be no problem reading the mma number mix again. In fact, there is now a lot of development for today’s smart phones. So in this barrier, there are more than old versions of smart phones, so repairs need to be created first.
These types of network problems are actually compatible with various carriers as well as phones. For this, you are immediately confused because everything is still being solved well. There are still many solutions that can be applied to ensure that you have incorrect MMI connection or code. But actually the newest smart phones have the least errors.
