Some owners of an Internet connection from popular mobile operators encounter error 633 when using a USB modem: “The modem is in use or not configured.” But there’s no need to panic, it’s better to first figure out what’s going on. To eliminate the problem, it is necessary to establish reliable causes that provoked it, as well as determine a method for eliminating it.
Usually error 633 occurs while working through Dial-up.
This is due to the fact that when connecting to a remote device, due to the line condition, the connection freezes. There is no network connection on Windows XP. A reboot will help fix the failure of the Beeline modem and other popular mobile providers.
The factors causing the modem error in question on a high-speed ADSL connection are as follows:
Every malfunction on a mobile MTS, Beeline or Megafon modem is quite simple and understandable. But there is another factor due to which the device does not activate. This is a malfunction of the modem driver.
Let's consider the last case in more detail.
Drivers
The 633rd error due to drivers being incompatible or not working correctly is the most confusing and difficult for most users. The action plan is as follows:
Removing incompatible software
Another common reason for lack of Internet access is the uninstallation of incompatible software. Error 633 occurs because the selected utilities are incompatible with the operating system. 
To solve such a problem, it is better to remove these utilities, and the problem will go away by itself. However, this must be done in safe mode. To do this, activate the F8 key when turning on the device. 
If the subscriber does not have enough professional knowledge, he does not understand what exactly needs to be deleted, it is recommended to turn off the services operating system using ISS. 
But first eliminate the connection to the FTP server. 
Port configuration issues
There are times when error 633 occurs due to the COM port being occupied by third-party equipment or a program. In such situations, it is necessary to clear the entrance.
Sometimes users mobile internet from Beeline, MTS, Megafon or Intertelecom, when working via a USB modem, may encounter connection error 633 - “The modem or other communication device is in use or is not configured.” In the case of a cable connection via an ADSL modem, this also occurs, but much less frequently.
The first time I encountered this was when working through Dial-up. At that time, connection error 633 was a frequent visitor to me. The fact is that after connecting to the provider’s remote modem, after some time the connection froze due to poor line quality. Moreover, online Windows connections XP the connection state was inactive, but attempts to start it ended with a message that the modem was already in use. Rebooting the modem helped, and sometimes I had to restart the computer.
On a more modern and high-speed ADSL connection, or connection via a 3G/4G modem, error 633 usually appears as a result of one of the following reasons:
1 - The modem has stopped working. Try disconnecting the modem and connecting again. Did not help? Try restarting your computer.
2. - Modem driver failure. First, try simply unplugging it and plugging it back into the adjacent USB connector. If it doesn't help, try completely uninstalling the modem driver and the program that came with it. Then reboot and install everything again.
3. - The COM port for the modem is not selected correctly. This happens when one COM port is selected in the modem settings, and another is selected in the device manager. Try rebooting Windows XP without disconnecting the modem. Error 633 persists? Then manually set both to the same COM port number. Only again there is a chance to choose an already occupied one.
4. - Installed program- Connection Manager - already uses a modem. At the same time, if you try to start a connection via Network connections Windows, then most likely you will receive a message that the modem is busy. In this case, you do not need a dialer - the program starts the connection. Well, or uninstall the program and start the connection manually yourself.
5. - Well, another reason is banal human inattention. I have met several times people who, with an already running PPPoE connection, tried to launch another one. It is clear that beginners are guilty of this, but nevertheless, this scenario occurs quite often.

Error 633: causes and solutions
When using modems of any type, failure number 633 (connection error) appears quite often. And although today the use of modems is, to put it mildly, outdated, nevertheless, for some systems such a connection may be relevant (for example, when starting a modem mobile device in order to gain access to the Internet from a computer). The problem can be fixed quite simply.
Error 633 (modem in use or not configured): the essence of the problem
It is believed that the failure is mainly due to the obsolescence of the maintenance software (drivers) and incompatibility with the system of management utilities.
In some cases, error 633 may occur only because the COM port intended for software connection of the modem is busy. Thus, there seem to be three main solutions to this problem.
Error 633. Modem. Drivers
First of all, you should pay attention to installed drivers. In the simplest case, if error 633 appears, you should not only try to update the drivers through the Device Manager, but also completely remove the device from the system.
After this, you should not install drivers from the database Windows data, since the system installs what it thinks is the most suitable driver. If there is a companion disk, it is better to use it. But to install the most latest versions It is common to use automated search and update programs like Driver Booster or even DriverPack Solution, which are able to recognize devices installed on the system and access the manufacturer’s resources on the Internet to download the most current versions of drivers directly.
Removing incompatible software
Sometimes error 633 can occur due to the fact that additional management utilities are simply incompatible with the operating system.
Naturally, they need to be removed. This is done through the add and remove programs section in the standard “Control Panel”. If the installation date of such software upon first connection is known, you can simply sort programs by this criterion. And it is advisable to perform deletion in safe mode, using the F8 key in most cases when starting the system.
If the user does not know exactly what needs to be deleted, he will have to turn to disabling unnecessary services through the same section, but with a selection of system components. In this case, we are talking about ISS services, where you must first deactivate access to the FTP server and website management tools.
Port configuration issues
But sometimes in cases where error 633 occurs, it happens that at the time of connection the corresponding COM port is occupied by another device or software.
To get rid of this failure, you will need to release the port. This is done on initial stage by deleting all existing connections in the Network and Internet section. After this, you need to go to the “Device Manager” and when you click on the network adapter, use context menu, in which the property line is selected. On the “Advanced” tab in the port settings, you should change the port number from the first to the third or from the second to the fourth (you cannot change the odd port to an even one).
Next you need to reboot the system and go to properties again installed modem, corresponding to, for example, a VPN connection, and then use the modem poller call. In most cases, this method corrects the situation when error 633 appears.
It remains to add that these are the simplest methods and solutions, since in each specific case the problem may have different causes. However, not to mention the accompanying software, the first thing you need to pay attention to is ports and drivers.

How to resolve error 633 in Windows XP, 7
I used to often use my phone as an internet hotspot. Tried it different connections, USB cable, infrared port, even bluetooth. In every possible case, sooner or later error 633 popped up. Given my youth and inexperience, I sinned on mobile operator, however, the network worked - I could use the web on the phone. Then it was time to figure out what was the cause of the error. I found a crude solution that helped in 99% of cases: I simply rebooted both the phone and the computer. Later, through trial and experimentation, I began to change the USB port connecting the device to the PC and rebooting only the phone. The torment ended there until I purchased a 3G modem. Previous methods the solutions simply stopped helping. By the way, the error has also almost outlived its usefulness, but from time to time I saw the hated code on the monitor. That’s when I realized that viruses were rampant on the computer and were slowly eating up the drivers one by one. The treatment helped, and the modem no longer bothered me.
Rebooting the modem
The first thing you need to do when error 633 appears is to reboot the modem. Technical documentation says that it is enough to turn off the device for 15 seconds to get rid of static electricity. In addition, it is advisable to change the USB port if a cord or adapter is used when connecting a modem, and restart the computer itself.

Some Windows components can also block the operation of the modem, mainly IIS services, namely the FTP server. In this case, correcting the error will require disabling certain protocols, and to do this you will have to use the appropriate interface:
- Open the “Control Panel”, go to the “Programs and Features” applet (the tool may also be called “Add or Remove Programs”).
From the “Control Panel” components, select “Programs and Features”
- Next, on the left, click on “Turn components on and off.”
Click on “Turn components on or off”
- In the window that opens, find and open the “IIS Services” column, uncheck the FTP server item. Save the changes with OK.
Uncheck the FTP server folder and save the changes
- We try to connect to the Internet again.
