Operating system name and version: Debian 9
Version of smsd: 3.1.15-2
Smsd installed from: sources
Name and model of a modem / phone: Huawei E3531
Interface: /dev/ttyUSB0

Hi, I wonder if someone can help me.

I am trying to set up smstools, and so far it seems I can send without problems, but i am having less success with receiving them - or at least messages sent to the E3531 do not appear in the 'incoming' folder.

(If i plug the E3531 in to a windows PC and go through the HiLink web interface, the received messages are listed - i assume this is an indication that the messages are being stored on internal memory rather than the SIM card.)

my smsd.conf is:



Looking at the 'I cannot receive messages' section in the FAQ, changing the init string to AT+CPMS="ME" does not seem to have any effect, and changing the init string to "MT" as below


gives the error in the log
2017-08-30 15:40:37,2, smsd: Smsd v3.1.15 started. 2017-08-30 15:40:37,2, smsd: Running as smsd:dialout. 2017-08-30 15:40:37,4, smsd: File mode creation mask: 022 (0644, rw-r--r--). 2017-08-30 15:40:38,3, GSM1: Unexpected input: +CSQ: 13,99 OK 2017-08-30 15:40:50,3, GSM1: Modem did not accept the init string, Operation not allowed 2017-08-30 15:41:12,3, GSM1: Modem did not accept the init string, Operation not allowed

What would be the best way to proceed?

Thanks in advance.

As you have tried with SM and ME memories, and both are empty even when there should be a message received, the device likely is broken or not compatible with standard AT commands.

Some time ago there have been two similar situations here:
[solved] Cannot receive SMS with Huawei E3131
[answered] not receiving sms

Possibly the situation sounds pretty similar, so look at those posts first.

One more thing, please check what is the firmware of your device:

- stop the smsd if it's running
- start smsd in communication mode: smsd -C GSM1
- press enter and give a command: AT^FHVER

What is the response?

Thanks for your help with this Keke, it is much appreciated.

Entering AT^FHVER gives

"E3531i-2EA 22.521.31.00.400,CU1E3131IM Ver.A"

I will start to work my way through the other forum threads you suggested now.

So, using a terminal connection smsd -C GSM1

if I enter AT+CPMS? it returns
+CPMS: "SM",0,20,"ME",0,20,"ME",0,20

then if i send a message to the E3531, and AT+CPMS? again it returns
+CPMS: "ME",1,20,"ME",1,20,"ME",1,20

and then immediately afterwards entering AT+CPMS? again it returns
+CPMS: "ME",0,20,"ME",0,20,"ME",0,20

Is it interesting that "SM" only appears in the returned string, on the first attempt before the message is received by the stick?

I believe I have had a bit of a break through

using these settings in smsd.conf i can send and receive messages with the E3531



It seems the issue was with the CNMI mode. It seems as default the E3531 is set to 2,1,2,2,0 (or my one was at least).

Hi dears,
i am new using the forum but not using SMSTOOLS3 and was facing a similar problem.
SMS were received but not shown in my webapp.
While checking smsd.log file I noticed that ME memory was growing up after each test message sent

So I finally solved the issue with this config file:



Hope it will help somebody!

Thanks Keke for this great piece of software!

God bless you
