Connection problem or invalid MMI code
When you try to contact theoperator’s number using a smartphone and then a pop-up connection problem or invalid MMI code appears to be written, of course, it is very confusing. Especially if at that time you really need special information from your respective operator| However, there may be an error in the code entered due to a special reason.
However, as a user, you really have to first understand how an MMI code can be considered inappropriate| So really, it can be really cool and can’t get confused as the issue can be solved independently later, then try to contact the operator as per your needs| Although you really 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 cause of connection problems or invalid MMI codes| So it is really necessary to wait a few seconds to see if the operator can be contacted then | there is no need to immediately worry that your smartphone is getting wasted because it is related to the operator’s network.
So understand better when this happens and have patience in waiting| If this is not resolved when you try again, you can start trying to apply a few steps, this can actually be done as a solution to the error in the MMI code . You don’t have to come to the service place, this condition can still pass by itself |
Understand your phone’s MMI code error
The Man Machine interface stands for MMI in the form of code | this code is a special service created to be able to access various features on your phone . The special code consists of several combinations of symbols and numbers |, however, it is easier when you need your respective operators to use special features |
The use of this special code is when you need to get information on internet quotas or credits, as well as IMEI, and other requirements. However, there is still a lot of potential for connection issues or the advent of invalid MMI codes as they interfere with the process when you need to check some information on your network according to their personal needs|
Various things will cause an error in combining these symbol numbers, for example because network settings settings occur incorrectly and many nonsignificant files may still be stored in phone memory. A code error occurs because if a temporary bug appears on the phone, and the lack of support in the operator’s signal is decreasing.
So really, the existence of a connection problem on the phone or an invalid MMI code is nothing serious and even requires special management| Users can actually apply alternative measures based on these possible reasons so that it will be easier to be able to correct the errors later .
Practical tips to minimize errors in special codes
Many initial solutions are actually much easier to use as solutions if there is a connection problem or the MMI code is invalid| It is possible that because there 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. If there is a bug in the phone then this move will actually help in fixing |
After waiting for a while to return the normal signal, the next option solution may make it easier for you to try to turn on Plan mode on the smartphone. This is a very helpful solution for modifying your signal and accurately capturing it by the phone.
When you find a connection problem or an invalid MMI code, this may be because the less important storage is actually stored in memory. Yet the practice of leaving documents less important to your memory will certainly interfere with its performance| It is therefore important that you try to get used to checking the file manager section and start diligently deleting non-important documents in memory.
Catching up from your phone and clearing various non-important files will make more memory available for other purposes. In the Settings section, however, you can easily find storage sections that can actually be cleaned. Doing it regularly is also very helpful to keep the performance and memory of the smartphone at its best|
To put a certain mark in the operator’s number combination
If indeed the previous quick technique still certainly won’t be able to change the connection problem or if the MMI code is invalid and still has problems, try applying other measures| Inserting a special mark in the operator code while communicating with the operator can be an option so that the error can be resolved .
You can insert a + sign at the beginning of the typed code. For example, the code you need is to call *123# then try writing *+123#. How to hold the number longer + sign will be received. This method may sometimes succeed in removing the problem of invalid code errors on your phone.
Another special sign that can also be used is the comma | but like the previous character, you have to insert this comma character at the end of the code. For example, *123, #ଲେଖୁଛି. The way to get a comma in the dial up is to hold the * button longer |
The insertion of this character is actually a step that is rarely known or done| If indeed you’ve done everything else, but it hasn’t succeeded, of course, it would be very helpful to insert a character| But note and check again for connection issues or invalid MMI code that you use it the right way|
The occurrence of errors can also be found in reading the special code of | given command , therefore, an important step can be taken as the solution will apply by giving these special characters| Try applying it, for example, a connection problem or an invalid MMI code still persists.
Improved solutions on how to change signals
Nis, a network on smartphones with a large signal power widely used today, is 4G LTE | However, this signal service also often leads to errors such as connection issues or invalid MMI codes | That barrier exists because of the lack of support of these signals when there is a need to communicate and to communicate with regular short messages| Of course, the priority of the network is because the main focus is on internet networks|
So in eliminating this problem, you can try to temporarily change the 3G signal from using 4G. However, only to meet the requirement of telephone short messages so that the network is more friendly. This will minimize the occurrence of problems or errors in the special code while communicating with the operator|
To change this you can go to the phone’s settings section then take the Mobile network option . In those options , there will be the option to set the network that will be used on your phone. It only has to change it from 4G to 2G/3G, which then saves settings and tries to make an operator call like Startup.
This way your phone network will become stronger and there will be no problem in reading the combination of MMI symbol numbers again. In fact, there has been a lot of development in today’s smartphones now. So in this restriction, there is more to the older version of the smartphone so it is necessary to make adjustments first|
Such network problems | really possible on various carriers and mobile phones So, you don’t get confused immediately because everything can still be solved properly | there are still many solutions that can be applied so that your connection problem or invalid MMI No code, but actually the latest smartphones will have minimal errors|
