 Invalid CONNECTION or MMI Code Issue


When you try to call theoperator’s number using k an smartphone then pop up the writing of connection problems or mmi code  is not valid is certainly quite confusing. Especially if you really need special information  from your respective operators. All of course there could be an error in the code entered due to a special cause.

Of course, as a user, you must understand first howan MMI code  can be considered inappropriate.  So it can  actually be calmer and do not be confused because later this problem can be overcome independently, and then try to contact the operator according to their respective needs.  Although you have to pay attention to a few steps first.

The existence of this particular step  cannot be applied at once  when trying to reduce the connection problem factor or invalid MMI  code.  So it is necessary to wait a few seconds to be able to see if then the operator can be contacted or not. No need to immediately worry that your smartphone is being damaged because it is related to the operator’s network.

So when it happens understand  well and patiently in waiting.   If it is not yet resolved when tried again you can start trying to apply some steps can indeed be done as an error solution in the MMI code. Do not have to come to the service place, this condition can still be overcome by yourself.

Understanding Your  Phone’s MMI Code  Error

Man Machine Interface stands for MMI in the form of the code. This code is a special service made for you to make access to  various features on your phone. The special code does consist of  several combinations of symbols and numbers. Of course, it is made to make it easier when you need to use special features  to their respective operators.

Theuse of this special code is when you need to get internet quota or credit information, as well  as IMEI, and other needs.  But there are still many possibilities for the emergence of connection problems or  invalid MMI code is also quite annoying because it makes it hamper the process when you need to check certain information  on your network according to their respective needs.

Various  things will cause errors in  the combination of  this symbol number for example because the setting of the network settings occurs incorrectly and there may still be many unimportant  files  stored in the phone’s memory.  The error of the code  occurs because if a temporary bug appears on the phone, so is the  lack of support on the operator signal is decreasing.

So indeed the problem of an  invalid MMI connection or code  on the phone  is not something  serious and even requires special handling.  Users can indeed apply alternative steps  based on the possible causes so that later it will be easier to be able to fix errors.

Practical Tips to Minimize Special Code Errors

Many  initial  solutions are actually quite easy to be used as a solution if there is a connection problem or invalid MMI  code.  It is possible that the  cause is a bug in your signal network so the solution is to restart  the phone, and then wait a few seconds before trying to contact the operator. This step will indeed help in fixing if there are bugs on the phone.

The next alternative  solution can be easier for you to try to turn on the plan mode on the smartphone, after waiting for some time to return  the normal signal. This solution is very helpful to make your signal repaired again and quickly captured properly by the phone.

When finding writing connection problems or  invalid MMI code can be because less important deposits are stored  in memory. The habit of still leaving documents less important to your memory will certainly eventually interfere with its performance.  So it’s important that you try to get used to checking the file manager section and start diligently deleting  unimportant documents in the memory.

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

Give a Certain Mark in the Operator Number Combination

If indeed the previous quick trick still cannot be definitively able to change the connection problem or mmi code  is invalid and there is still  interference then try to apply other steps.  Inserting a special mark  on the operator code when you contact the operator can be an alternative  so that the error can be resolved.

You can insert the +  sign at the beginning of the typed code.  For example, the code you need is to  call *123# then try to write *+123#. The + sign will be obtained how to hold the number zero longer.  This method can sometimes  be successful in solving the problem of invalid code error on your phone.

Another special  sign that can also be used is a comma. But unlike the previous character, you have to insert this comma character at the end of the code. For example, write *123,#. The way to get commas on the dial up is to hold the button for longer* longer.

The insertion of this character is indeed a step that is rarely known or done. If indeed all other ways you have done, but not yet successfully of course inserting a character will be very helpful. But pay attention and check back the connection problem or invalid MMI code you use it in the right way.

The occurrence of an error in reading the specific code of the given  command may also be found. Therefore, important steps can be done as a solution will be applied by giving the special character.  Try to apply it for example there is a connection problem or invalid MMI  code  still continues to exist.

Advanced Solutions How to Replace Signals

Anetwork enis in smartphones with large signal strength  widely used today is 4G LTE. But this signal service  also still often brings up errors such as connection problems or  invalid MMI code.  The obstacle exists due to the  lack of support  of this signal when the need to contact is also a regular short message. Of course, the priority of the network is because the main focus is on the internet network.

So in solving this problem you can try to temporarily change the 3G signal from the use of 4G. Of course, only in meeting the needs of short phone messages so that the network is more optimal. This will minimize the occurrence of obstacles or errors in the special code  when contacting the operator.

To change it you can go to the settings section of the phone and then take the mobile network option . In that option later out the option option to set the network to be used on your phone. Just change it from 4G to 2G/3G, after which save the settings and try to make the operator call as it was.

That way your phone network will be stronger and not until there are obstacles in reading  the MMI symbol number combination  again. Indeed, there are currently many developments made to smartphones today. So in this  obstacle more is in the old  version of smartphones so it is necessary to make adjustments first.

Such network problems  are indeed possible in various carriers and mobile phones. For that, you should not then immediately confused because everything can still  be resolved properly. There are still so many solutions that  can be applied so that you do not let the connection problem or mmi code  is invalid, but indeed  the latest smartphone output  will be minimal error.
