Connection problems or invalid MMI code

Of course, when you try to contactthe operator’s number using a smartphone, and then a pop-up appears writing connection problems or invalid MMI codes, it is quite confusing. Especially if at that time you really need special information  from your respective operator. Everything , of course, there may be an error in the code indicated due to a special reason.

Of course, as a user, you really first need to  understandhowan MMI code  can be considered inappropriate.   So, in fact, it  can be quieter and not to be confused because later this problem can be solved independently, trying to contact the operator according to their respective needs.   Although, in fact, you have to pay attention to a few steps first.

The existence of this step cannot be used right away  when trying to reduce the factor of  connection problems or  invalid MMI codes.   So, in fact, it is necessary to wait a few seconds to see if the operator can be contacted or not. You don’t have to immediately worry about your smartphone getting damaged because this is related to your carrier’s network.

So when that happens understand well and be patient in waiting.   If it is not resolved  when you try again, you can start trying to use some steps, it can actually be done as a solution to the error in the MMI code. No need to come to the place of service, this condition can still be overcome by yourself.

Understand your phone’s  MMI code

Man Machine Interface stands for MMI in terms of code. This code is a special service created for you to be able to access various functions of the phone. The special code consists of several combinations of symbols as well as numbers. Of course, it becomes easier when you need to apply special features  to their respective operators.

The use of this special code is when you need to get information about internet quota or credit, as well as  IMEI and other needs.   However, there are still many possibilities for the emergence of connection problems or invalid MMI codes are also quite annoying because they hinder the process when you need to check certain information on your network according to their individual needs.

Various things will cause an error in the combination of these symbol numbers, for example, because the network settings happen incorrectly, and there may still be many unimportant files stored in the phone’s memory.   The error  in the code  occurs because if a temporary error occurs on the phone, as well as because the lack of support on the operator’s signal decreases.

So, in fact, the existence of a connection problem or  an invalid MMI code on the phone is  nothing serious and even requires  special handling.   In fact, users can use alternative steps  based on these possible reasons, so that later it will be easier to be able to fix errors.

Practical tips to minimize the error of special codes

Many  of the  original 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 failure in your signal network, so the solution  is  to restart the phone  , and then wait a few seconds before trying to contact the operator. In fact, this step will  help in fixing if there are errors on the phone.

The next alternative  solution may be easier for you to try turning on plane mode on your smartphone, after  waiting for a while to return the  normal signal. This is a very useful solution  to make the signal  corrected  again and quickly captured correctly by the phone.

When you find a connection problem or an invalid MMI code, it could be because the less important storage is actually stored in memory. The habit  of still leaving documents that are less important to your memory will surely end up interfering with performance.   So, it is important that you try to get used to checking the file manager section and start  diligently  deleting  unimportant documents in memory.

Clearing the cache and various unimportant files from your phone will make more memory available for other purposes. Of course, in the settings section, you can easily find the storage part that can actually be cleaned. Doing it regularly is also very useful to keep your smartphone’s performance and memory optimal.

Put a specific mark on the operator’s number combination

If the previous  quick trick still cannot be surely able to change the connection problem or  the MMI code is invalid and there are  still  problems, you can try using other steps.   Inserting a special mark in the operator code when contacting the operator  , can be an option so that the error can be fixed.

You can insert a + sign at the beginning of the written code.   For example, the code you need to dial * 123 # and try to write * + 123 #. The + sign will be obtained how to keep the number zero longer.   This method can sometimes  successfully overcome the issue of invalid code errors on your phone.

Another special  sign can also be used is a comma. But unlike the previous character, you need to insert this comma character at the end of the code. For example, typing *123,#. The way to get a comma in the dial is to  hold the * button longer.

The insertion of this character is actually a step rarely known or done. Of course, if you have done everything else, but it has not been successful, inserting a character will be very useful. But pay attention and check again for connection problems or invalid MMI codes you are using it properly.

The occurrence of an error when reading the special code of the given  command can also be found. Therefore, an important step can be made as a solution will be applicable  by providing these special characters.   Try using it, for example, there is a connection problem or  an invalid MMI code still persists.

Advanced solutions How to change the signal

Anetwork enis in smartphones with great signal strength that is widely used today is 4G LTE. However,  this signal service  also often raises errors such as connection issues or invalid MMI codes.    That obstacle exists due to the  lack of support  for  this signal 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 4G. Of course, just to meet the needs of  calling card messages so that the network is more optimal. This will minimize the occurrence of problems or errors in the special code when contacting the operator.

To change it, you can go to the settings section of your phone and then take the cellular network option. In that option , there will be options to set the network to use on your phone. It remains only to change it from 4G to 2G / 3G, after which you save the settings and try to call an operator as the beginning.

That way, your phone network will be stronger and there will be no problems reading  the  combination of MMI symbol numbers again. In fact, there have currently been many developments to today’s smartphones . So, in this  obstacle there are more  in older versions of smartphones,  so adjustments must be made first.

Such network problems are actually possible in different carriers as well as mobile phones. For that, you  will not be  immediately confused because everything can still  be fixed properly. There are still so many solutions that  can be used so that you don’t have  connection problems or invalid MMI codes, but in fact, the latest smartphones will  have minimal errors.
