Connection problems or invalid MMI codes: Mocipay

If you try to contact the operator’s number using your smartphone and see a pop-up that says something wrong with  the connection or writes  invalid MMI code, then of course, it can be quite confusing. Especially at that point, if you really need special information  from each operator. Of course, there may be errors in the code entered due to special causes.

Of course, as a user, you must first understand how MMI code is considered inappropriate. So you can actually calm down and avoid getting confused because you can solve this problem independently later, and then Try to contact the operator according to the needs of each one. Although surely you need to pay attention to a few steps first.

The presence of this particular step is immediately applicable  when trying to reduce the factors of connection problems or invalid MMI codes You can’t. Therefore, you will have to wait a few seconds to see if you can contact the operator. Since this is related to the operator’s network, you don’t have to worry right away that your smartphone is damaged.

So, when it happens, understand well, wait and be patient  . If trying again doesn’t help, you can try to apply some steps, it’s actually an MMI code error It can be done as a solution. You do not need to come to the service place, this condition can still be overcome by yourself.

Understand  your phone’s MMI code error

Man Machine Interface stands for MMI in code form. This code is a special service created  to allow you to access various functions of your mobile phone. A special code consists of several combinations of symbols and numbers. Of course, it will be easier if you need to use special functions for each operator.

The use of this special code is when you need to obtain information such as internet quotas and credits,  IMEI etc. However, connectivity problems and  the appearance of  invalid MMI codes can lead to specific information on the network, depending on  the needs of the individual   There is still a very annoying possibility as it hinders the process when you need to make sure.

Combining these symbol numbers because the network configuration is not correct and  there may still be many unimportant files  stored in the phone’s memory. There are a variety of causes.   Code errors, if a temporary bug appeared on the phone, and the lack of support for the operator’s signal   Occurs because it is decreasing.

Therefore, connection   problems or invalid MMI codes on the phone are not serious and require special handling.  Users can actually apply alternative steps based on these possible causes so that they can easily correct the error later.

Practical tips to minimize errors in special code

Many of  the initial solutions  are actually very easy to use as solutions when  there is a connection problem or when the MMI code is invalid. Since the cause could be a bug in the signal network, the solution is to restart the phone, wait a few seconds and then try to contact the operator 。 This procedure will actually help you fix bugs on your phone.

The next alternative solution is easier   to wait for a while to return a normal signal and then try to turn on  Plan Mode on your smartphone. 。 This is very useful for correcting the signal again and capturing it quickly and properly on the phone The solution.

If  you find connectivity issues or  invalid MMI codes, less critical storage may actually be stored in memory. The habit of still leaving documents that are not so important to your memory will certainly  hinder its performance. Hence get  used to checking the File Manager section and eagerly delete unimportant documents in memory It’s important to get started.

Clearing cache and various unimportant files from your phone will increase the memory available for other purposes. In the settings section, of course, you can easily find the storage section that you can actually clean. Doing it regularly  can also be very helpful to keep the performance and memory of  your smartphone optimal.

Mark a combination of operator numbers specifically

Actually the previous quick trick is still  a connection issue  that cannot be reliably changed or the MMI code is invalid and still  If you have problems, try applying the other steps. Inserting a special mark in the operator code when  contacting the  operator    resolves the error   It is an  alternative to be able to do so.

You can insert the +  sign at the beginning of typed code. For example, the code you need is to call *123# and then try to write *+123#. The + sign gives you a way to hold the number zero longer. This method may succeed in overcoming the invalid code error issue on your phone.

Another special symbol is a comma. However, unlike the previous character, this comma character must be inserted at the end of the code. For example, *123,#. The way to get a comma on dial-up  is to press and hold the * button .

The insertion of this character is actually a rarely known or done step. If you’ve actually done everything else but haven’t had any success, of course, inserting characters can be very helpful. But pay attention and double-check for connection issues or invalid MMI codes.

An error reading the special code for a specified command can also be detected. Therefore,  you can take important steps to ensure that the solution is applicable by giving these special characters. For example, if there is a problem with the connection, or if there is still an invalid  MMI code, try applying.

Advanced Solutions How to Change the Signal

The network of smartphones with great signal strength that is widely used today  is 4G LTE. however this signals service   often encounters errors such as connection problems and invalid   mmi code 。  Lack of support  for this signal when its failure should be contacted as well as a normal short message It exists for: Of course, the priority of the network is because the main focus is on the Internet network.

Therefore, to overcome this problem, the  3G signal can be temporarily changed from the use of 4G. Of course, only if you meet the needs of phone short messages so that the network becomes more optimal. This minimizes problems or errors with special codes when contacting operators.

To change it, go to the settings section of your phone and select the mobile network option. That option includes the option to configure the network used by the mobile phone. Just change from 4G to 2G/3G, then save the settings and try to call the operator as in the first place.

That way, the phone network will be stronger and you won’t have any trouble reading the MMI symbol number combination again. Indeed, there are many developments taking place right now  in the smartphone of the day . Therefore, with this obstacle, there are many more  in  older versions of smartphones,  so You need to make adjustments first.

Such network problems are actually possible not only on mobile phones,  but also with various carriers. Because of that,  everything can still be solved properly, so  you won’t be confused right away.  There are still many solutions that can be applied to ensure that there are no connection issues or  invalid MMI codes  However, in practice the errors on modern smartphones  are minimal.
