Connection Problems or Invalid MMI Code
When you try to contact theoperator number using a smartphone and then a pop up is seen writing connection problems or invalid MMI code, of course, it’s quite confusing. Especially if at that time you really need special information from your respective operator. Of course, there may be an error in the entered code due to a special cause.
Of course, as a user, you really need to understand first how an MMI code can be considered inappropriate. So indeed, it may actually be calmer and not confused because later this problem can be solved independently, then try to contact the operator according to their respective requirements. Although indeed you have to pay attention to a few steps first.
The existence of this particular stage cannot be applied right away when trying to reduce the connection problem factor or invalid MMI codes. So it is indeed necessary to wait a few seconds to see if then the operator can be contacted or not. There is no need to immediately worry that your smartphone is being damaged because this is related to the operator’s network.
So when this happens understand well and be patient in waiting. If it is not solved when you try again, you can start trying to apply some steps, it can indeed be done as a solution to the error in the MMI code. You don’t have to come to the place of service, this condition can still be overcome on your own.
Understanding Your Phone’s MMI Code Error
Man Machine Interface stands for MMI in code form. This code is a special service created for you to be able to access various features on your phone. The special code consists of several combinations of symbols as well as numbers. Of course, it is easier when you need to use special features to their respective operators.
Using this special code is when you need to get information about the quota or credit of the internet, as well as the IMEI, and other requirements. However, there are still many possibilities for the emergence of connection problems or invalid MMI codes are also quite annoying because they disrupt the process when you need to check certain information on your network according to their individual needs.
Several things cause an error in the combination of these symbol numbers, for example because the network settings setting occurs incorrectly and there may still be many unimportant files stored in the phone’s memory. The code error occurs because if a temporary bug appears on the phone, as well as because the lack of support on the operator signal is decreasing.
So indeed, the existence of a connection problem or invalid MMI code on the phone is not something serious and even requires special handling. Users can indeed apply alternative steps based on these possible causes so that later it is easier to be able to fix errors.
Practical Tips to Minimize Special Codes Error
Most of the initial solutions are actually quite easy to use as solutions if there is a connection problem or the MMI code is invalid. It is possible that the cause is a bug in your signal network so the solution is to restart the phone, then wait a few seconds before trying to contact the operator. This step indeed helps in fixing if there are bugs on the phone.
The next alternative solution may be easier for you to try turning on the plane mode on the smartphone, after waiting a while to return the normal signal. This is a very useful solution to correct your signal again and quickly get caught properly by the phone.
When you find a connection problem or an invalid MMI code, it may be because the less important storage is indeed stored in memory . The habit of still leaving documents less important to your memory certainly ends up interfering with its performance. So it is important to try to get used to checking the file manager section and start diligently deleting unimportant documents in memory.
Clearing cache and several unimportant files from your phone make more memory available for other purposes. In the settings section, of course, you can easily find the storage section that can indeed be cleaned. Doing this regularly is also very helpful in keeping smartphone performance and memory optimal.
Placing a Specific Mark on the Combination of Operator Numbers
If indeed the previous quick trick still can’t be sure it can change the connection problem or the MMI code is invalid and there are still problems, then try applying other steps. Entering a special mark in the operator code when contacting the operator can be an alternative so that the error can be resolved.
You can enter a + sign at the beginning of the typed code. For example, the code you need is to call *123# then try writing *+123#. The + signal is obtained as you keep the zero number longer. This method can sometimes succeed in overcoming the problem of invalid code errors on your phone.
Another special sign can also be used is the comma. But unlike the previous character, you must enter this semicolon character at the end of the code. For example, writing *123, #. The way to get a comma in dialing is to keep the * button longer.
Inserting this character is indeed a step that is rarely known or made. If you did indeed do everything else, but failed, of course, inserting a character would be very helpful. But be careful and check again for connection problems or invalid MMI codes that you use in the right way.
The occurrence of an error reading the special command code of the particular command can also be detected. Therefore, an important step can be made by applying a solution by giving them these special characters. Try applying it, for example, there is a connection problem or an invalid MMI code still persists.
Advanced Solutions How to Change Signal
Networkenis in smartphones with great signal strength widely used today is 4G LTE. However, this signal service also often triggers errors such as connection problems or invalid MMI code. That obstacle exists due to the lack of support of this sign when the need to contact as well as regular short messages. Of course, the priority of the network is because the main focus is on the internet network.
So to overcome this problem, you can try to temporarily change the 3G signal from using the 4G. Of course, just to meet the needs of short phone messages so that the network is more optimal. This reduces the occurrence of problems or errors in the special code when contacting the operator.
To change it you can go to the phone settings section and then take the mobile network option . In that option , there will be options to set the network that will be used on your phone. It remains only to change it from 4G to 2G/3G, after saving the settings and trying to make an operator call like the starter.
This way your phone network will be stronger and there will be no problems reading the combination of mmi symbol numbers again . Indeed, many developments have currently taken place in today’s smartphones . So at this hurdle, there are more in older versions of smartphones so adjustments need to be made first.
Such network problems are indeed possible in various carriers as well as mobile phones. For this, it is then not immediately shaken as everything can still be solved properly. There are still so many solutions that can be applied so that you do not have connection problems or invalid MMI code, but indeed the latest smartphones will have minimal errors.
