Meizu smartphones have shown sales records in recent years - they have become more convenient, more attractive, and most importantly, more economical. Even budget models show good performance, having an excellent camera and functionality.
However, most often the stones fly into Meizu's thriving garden because of Flyme's own firmware, which took the best from Android, but seasoned it with bugs and glitches. In this article we will talk about the error “SIM card is busy, try again later” and offer simple solutions.
Bug in Meizu: SIM card is busy. try later
Why do you need to clean your SIM card?
The SIM card stores all the subscriber's contacts and SMS messages that he has ever sent. Since a SIM card is a very small device, its storage is not infinite. Over time, the memory becomes full, and you cannot add a new contact to your address book or read an SMS.
SIM cards must be changed periodically, as they become unusable after prolonged use. You can do this for free at your operator's service center.
To ensure that your phone can always receive messages and you can add a new contact at any time, it is recommended to clear the chip’s memory from time to time. In addition, a similar procedure will be needed if the subscriber gives the SIM card to another person.
SIM replacement rules
You can get a new identification chip at the nearest operator’s office. Replacing an inoperative SIM card with a new one is carried out:
- After subscriber identification. A user who contacts a Megafon communication salon will have to present an ID card and fill out a form provided by the consultant. In some cases, the identification process involves an office employee asking the applicant several questions regarding recent transactions with the phone number being restored. The owner of the SIM card can entrust the unlocking of the chip to a third party - to do this, you need to write a power of attorney.
- For free. The subscriber will not have to pay for a plastic chip or office staff services. The operator makes money by fulfilling the terms of the contract concluded with the user, and not by selling equipment.
- With preservation of the number, user tariff and personal account status. Although the subscriber will receive a new SIM card, the terms of the contract with the operator will remain the same: the tariff and the set of connected options cannot be changed without the consent of the individual. On the other hand, the user will not be able to save the contacts on the SIM card. There is simply no way to remotely manage the data contained on the chip’s internal memory. Before replacing the card with a new one, it is recommended to manually overwrite the phone book on the internal storage of the device.
- On the territory of equipment registration. The user can replace the SIM card only in those offices that are located in the service branch area. For example, a resident of the Leningrad region will not be able to receive an identification chip with the previous number in the Moscow region. It should be noted that this restriction does not apply to the purchase of a new SIM.
How to clear SIM card memory on iPhone
Apple's mobile devices are significantly different from those produced by other phone manufacturers. Here, to delete all contacts, you will have to use iTunes.
iTunes is an application designed to synchronize iPhones with a computer. It is provided free of charge, and the download link is provided on the developer’s website.
To clean all contacts you need:
- Connect iPhone to PC via USB.
- Open iTunes on your computer.
- In the program, select your device and go to the “Information” section.
- Confirm synchronization of contacts.
- Open the “Advanced” section.
- Check the box like contacts.
- Click on “Replace” and then “Apply”.
This will remove all address book information from the SIM card. You can perform the procedure manually without using iTunes:
- Open the Contacts application.
- Select the subscriber you are interested in.
- Click “Edit” and then click “Delete contact”.
Each SIM card stores a different amount of information, so it is not possible to say exactly how many contacts you need to get rid of for the device to work correctly.
Why does my Android phone say that there is no space, although there is a memory card and it is not full?
If your device in the form of a microSD memory card (this is what is used on modern mobile electronics) displays an error indicating that the memory is full, then most often it is. Naturally, provided that we are talking about an old drive that has already been used before.
But what if a similar failure happens with a new or almost empty memory card?
Indeed, in this case the error becomes obvious. To correct an error, you need to identify the root cause of its occurrence, without eliminating which all further actions may be in vain.
And in order to understand why a smartphone may resist loading new data, it makes sense to study the following nuances of the operation of mobile devices with a memory card installed on board:
- Occupancy principle. After installing a removable storage device on your smartphone, all new information is automatically saved to microSD. All but not all. It is important to remember that all applications installed by default, software downloaded from the Google Play in-app store and APK files, which often remain after manual removal of utilities, cannot be saved to microSD, being automatically redirected bypassing it to the built-in storage.
Moreover, they cannot be transferred to a memory card, so failure to load proprietary Google software is most often due to this very circumstance.
- Occupancy volume. Another important point is that to perform daily scenarios, the operating system does not have enough RAM alone, which is why it still has to use some part of the built-in memory. This means that the latter cannot be filled to capacity. If this happens, then the smartphone may indeed produce errors and failures even for an additional flash card.
If, in fact, it turns out that everything is in order with the built-in memory of the smartphone, while the error continues to appear, then it’s time to identify technical problems with the media itself. It is noteworthy that this could be simple mechanical damage, wear due to overload, activated protection, defective or even incompatibility with the device (it doesn’t read the card and that’s it).
And it also happens that the user thinks that there is a memory card in the smartphone, but in fact there is not. And unlike all previous points, the presence of a card is checked in a couple of seconds.
If a notification about lack of memory appears on your smartphone every now and then, then first of all you should make sure whether there really is not enough memory.
How to clear SIM card memory on Android
On Android, the situation with deleting contacts is much easier. You can get rid of all the information from your notebook at once without using third-party software or a computer:
- Open the Contacts application.
- Hold one caller's name for a few seconds.
- Select the required contacts to delete or click “Select all”.
- Click on the trash can icon located at the bottom of the screen.
If you need to delete 1 or more subscribers, you should select them individually. You can also clear your address book manually through the profile of each contact.
Deleting contacts with third-party programs
Still haven't learned how to delete contacts on Android? Does the program for working with the phone book cause any difficulties? Then you need to remember that what you have in your hands is not an antediluvian telephone with a rotary dialer, but a modern smartphone with enormous capabilities. And what you don’t like here can be easily replaced.
If your current contacts program is causing you problems, download another program. To do this, you need to visit the Playmarket application store and enter the word “contacts” into the search. Here is a list of good applications:
- Contacts + from the developer Contacts Plus team;
- PixelPhope by Dorado Apps;
- ExDialer – Dialer&Contacts from Modoohut.
These are proven and very powerful applications for working with the phone book and contacts, and in Russian. The latest program has the largest number of settings - thanks to them, the contact list can easily be adjusted to your own needs
.
How to clear SIM card memory on a feature phone
Such devices are becoming increasingly rare among people. Nevertheless, millions of users continue to give preference to push-button phones.
To clean your SIM card you need:
- Open the phone book.
- Click on the “Delete” item.
- Select all contacts or an individual contact.
- Click on “SIM card”.
- Confirm the action by clicking the “Ok” button.
On some older phone models, it is not possible to clear the entire address book. Sometimes you have to delete each contact one by one.
Delete SMS from SIM card
The SIM card's memory fills up not only because of the large number of contacts. SMS messages make a huge contribution to filling the storage. Typically, a SIM card can store up to 200 SMS messages. The total number may vary depending on the operator. But in any case, it is necessary to periodically clean the corresponding section of the phone.
To remove it you need:
- Open the Messages app.
- Select all SMS messages, if the operating system allows.
- Click on the “Delete” button.
In the settings of some smartphones, you can specify that messages are saved not to the SIM card, but to the memory of the mobile device. You can find out more about this in the instructions for your phone.
Basic tools
The easiest way to delete a contact from an Android phone is to use basic functions. To do this, you need to go to the phone book and press your finger on the contact to be deleted. After a second it will be marked with a tick. At the same time, we will be asked to mark other entries. If necessary, select other contacts (put a check mark next to them), then go to the very top and click on the icon with the image of a trash can - the necessary contacts will be immediately deleted.
Sometimes the trash icon is missing, and the desired item is called up through the context menu - this depends on the basic program installed on the smartphone for working with contacts and calls.
All dialer programs have this functionality, so there shouldn’t be any difficulties here. Basic capabilities allow you to delete contacts stored in any sources
, starting from the SIM card and ending with your Goole account. To switch between sources, go to the application settings and find the contact list display settings item there (may be called “Show contacts”). By tapping on this item, you will see a list of sources:
- All contacts (the entire list is displayed at once);
- Device (referring to the internal memory of the phone);
- SIM1 and SIM2 (for devices with two SIM cards);
- Google account (visible as [email protected]).
There may also be other items here that appear after installing various applications (Messengers WhatsApp and Viber, applications for social networks VKontakte and Odnoklassniki).
If you want to access all contacts at once, select “All contacts” - records from all sources will appear in the list at once
. The process of deleting records will be the same as we described above - press one contact, mark other contacts, select the delete option.
To avoid confusion in phone numbers in the future, copy your phone contacts into one source. The best option is to copy everything to your Google account so that the records are synchronized with the servers of the Android operating system developer.
If all else fails
As a rule, even users who use the phone only as a last resort have no problems clearing the SIM card memory. But, if an error appears during the process, then the performance of the device itself is to blame. The SIM card or smartphone may be faulty.
The surest way to clear a SIM card in this case is to insert the chip into another phone and try to delete it on it. If this doesn’t help, you can try deleting contacts one at a time. Most often, this method allows you to get rid of unnecessary contacts and SMS.
As a last resort, you can contact the service center. But there they can demand a tidy sum of money from the client for solving seemingly very simple problems.
