Huawei E3531 (MTS 423S, Megaphone M21-4) - Discussion
DiscussionHuawei E3531 (MTS 423S, Megaphone M21-4)
As usual, modems from cellular operators are delivered blocked - they can work only with SIM cards of this operator. The list of plmn-codes allowed for use can be viewed with the commandat ^ simlock? .
Of course, this situation does not suit us - we want, having bought a modem, to use it with any sim card. For this, the manufacturer laid the opportunity to unlock the modem. This is done by entering the unlock code (nlock code ), calculated by a special tricky algorithm from the IMEI modem.
Calculator to calculate codes can be downloaded here (there are versions for windows and linux).
To unlock, follow these steps :
- Calculate the unlock code using the above calculator. Of all the codes he uses, code v201 .
- Insert someone else's sim card into the modem (sim card of another cellular provider, not the one who sold you the modem).
- Connect the modem to the computer.
Further, the control program (for stick-modems) or the web interface (for hilink-modems) will ask for the unlock code, which must be entered. All - the modem is unlocked and will work with any sim card.
In addition to entering the code through the program and the web interface, you can also enter it via the AT command. This is especially true for stick-modems under linux.
The team looks like this:
at ^ cardlock = "unlock code" - used code v201
RECOVERY ATTEMPTS:
The number of attempts to enter the code is limited10 attempts . If the wrong code was entered 10 times, the modem blocks further attempts - more, the at ^ cardlock command will not unblock it, even if you enter it with the correct code. If you still managed to exhaust all input attempts, that's okay - they are easy to recover.
This is done by such teams.:
at ^ datalock = "unlock code" - used code v201
at ^ maxlcktms = 10
10 is the new number of attempts (you can enter any number from 1 before 255 ). You can then enter the command at ^ cardlock with the correct code and unlock the modem.
Total:
consistently enter AT commands from top to bottom:
at ^ datalock = "NCK code" - used code v201
at ^ maxlcktms = 10 - you can enter any number from 1 before 255
#
at ^ cardlock = "NCK code" - used code v201

Types and features of modem firmware:
COPY(with a small edition). ORIGINAL.
For this modem, there are 2 fundamentally different types of firmware - STICK and HILINK. Firmware interchangeable, that is, in any modem you can flash any firmware.STICK
With this insertion device behaves like the classic USB-modem: AT-command has a port through which a connection can be via PPP-protocol (RAS). That's how work almost all 3G-modems previous generations. In this case, the speed is limited - no more than 20-30 Mbit per reception. Besides PPP-mode, there is NDIS mode. In this modem emulates network interface, through which data is transmitted, and through AT-port are only control commands. In this mode, the speed is not limited. The main feature of the stick-mode - to connect and channel support work is carried out by means of a computer operating system that is connected to the modem. In this case, the computer receives the IP-address directly from the mobile service provider via a DHCP request, and the modem operates as a network bridge passing packets from the computer to the cellular network and vice versa, without changing their way.
The initial USB stick stick composition is a virtual CD-ROM and microSD card reader. In order for modem ports to appear, you need to switch the composition. Under windows, this is done by carrier software available on a virtual CD, or by the huawei proprietary program Mobile Partner. Under linux, switching is done by the usb-modeswitch program. It is possible to prohibit the transformation of songs. This is done with the following command:
In this case, the modem immediately after switching on will look like a modem, 2 AT ports and a NDIS network card. CD and microSD will be excluded from the configuration. This mode is extremely convenient for using the modem in various home routers. To switch back the composition with switching, use the command:
Version numbers of stick-firmware always start at 21 — for example, 21.318.05.00.00.
Included with the Stick-firmware, the so-called Dashboard is flashed into the modem - an image of a virtual CD that appears in the system after the modem is connected. On this CD are the modem drivers for different operating systems, as well as a control program with which they establish a connection to the Internet, read SMS, make USSD requests, etc. There is a universal version of this program from the manufacturer of the Huawei modem (Huawei Modem), as well as specialized versions from specific telecom operators.

HILINK
With firmware HILINK modem operates in the router mode, and appears to the computer as a network interface (usb-ethernet-rndis). The computer receives from the interface network settings via DHCP, and then goes through the Internet, either through a wired LAN. All the care of establishing and maintaining a connection channel modem takes over the computer does not even notice that internet access is via sototvuyu network. In this mode, the modem has its own local IP-address (usually 192.168.8.1), visible from the side of the computer as the default gateway (default route), as well as the external IP-address is obtained from the cellular network. Between the cellular network provider and the local network (modem-computer) is carried out using the routing address translation mechanism (NAT). Provided port forwarding from the external network (port forwarding and DMZ).
Setting up the modem in this mode via WEB-interface, available in the modem, and are available through the local IP-address. Also, through the WEB-interface information is available on the modem status and signal the cellular network connection management, send-receive SMS-messages and USSD-command, the SIM-menu, and more. This is especially valuable for users of Linux, as well as for those who have not the modem is connected to the computer and to a home router. Setting up the modem via AT-commands like stick-in firmware, in a normal mode hilink-firmware is not performed, although it is possible in a special debug mode DebugMode.
The initial composition of USB-modem HILINK-is exactly the same as that of the stick - the virtual CD-ROM reader and microSD. Switching tracks the windows made a small program mbbservice, triggered by the built-in CD. Under linux does usb-modeswitch program. Staff Software Developer modem is not a mode without switching tracks. However, by such a modification mode firmware may make. At the same time lost a built-in card reader SD, but it is possible to use a modem with any router that supports the network card usb-rndis.
Version numbers of hilink firmware always start at 22 — for example, 22.318.05.00.00.
HILINK firmware consists of two parts - the firmware itself, and the WebUI (web interface). The first firmware is the main firmware, then the WebUI.

Hello. It is necessary to configure the modem Huawei E3531 (MTS 423S) to connect to a tablet on Android. Prior to this, the Huawei E171 modem (also from mts) was configured with Hyper Terminal - AT ^ U2DIAG = 0. Now after input, it gives error. Are there other ways?

Well, it does not fit in any way.
fundamentally different modems.

a complete shutdown (only modem) via Hyper Terminal will be like this:
AT ^ SETPORT = "FF; 1,2"
here you need to use ppwidget, but in general we have such a topic
Connecting "unsupported" modems to Android devices
good luck
Thank. The command passed, but the modem is still not visible on the tablet. And the second link for me is a dark forest.))
The problem is also relevant. does not connect to android 4.0.4

Hello! Has anyone found a router for this modem?
On TP-LINK TL-MR3020 V-1.8 with the latest official Russian firmware, this modem started without any shamanism!
Good day, there was also a problem with choosing a router for this modem, I don’t want to work on the D-Link DIR-620, Zyxel Keenetic II Giga (((Anyone have solutions with these routers? I don’t really have a third one to buy I want to...
Also in search of a solution to the question :(
I did not think that everything would be so sad when I bought this modem.

Hello ! There is this modem, it was decided to change the dashboard. Well, in general, and changed to HUAWEI Modem 3.0, and that’s all .... Norms were flashed, but COM ports were gone, it is defined only as a CD rom and sees a USB flash drive in the modem. can I somehow restore com ports?
