LtaP + Huawei ME909s-120 ussd codes

Wed Nov 18, 2020 12:34 am

I have LtAP (not mini) v6.47.7 with LTE Interface Huawei ME909s-120 ver 11.617.01.00.00

I can SEND SMS from device and receive it without any problem. LTE also work. BUT I like to send USSD Code to provider so I can activate some of feature of my SIM plan. But trying with this card doesn't work. It is not problem with card, have 2 of them, same problem.
So my question is, is it USSD SUPPORTED over this LTE Card ? Is it problem on RoS (can’t use ussd code OVER Huawei card) or on LTE Card (in mean that card don’t have support for USSD code).
I try same feature (USSD code) over Mikrotik R11e-LTE and it work instantly.

Using Terminal with R11e-LTE
/tool sms send type=ussd phone-number=*111*6*1*2*1# port=lte1
It activates additionl SIM plan

Same commad on Huawei….nothig hapend.
In log a see:
lte1: sent AT+CUSD=2
lte1: sent AT+CUSD=1,"*111*6*1*2*1#",15
lte1: rcvd +CMS ERROR: 305

Try diffrent codes, always error.

Someone used ussd on this card ?

Thanks

Hello

In meanwile I find sollution on this. On Huawei LTE Card it can't work ower "/tool sms send type=ussd" must use "interface lte at-chat input....."
Example"
Credit bilans on my provider is *131*1# . So it need to be concverted to "AAD82CA68A8D1A" using http://smstools3.kekekasvi.com/topic.php?id=288 (USSD Entry)

Full Terminal line
/interface lte at-chat lte1 input="AT+CUSD=1,\"AAD82CA68A8D1A\",15" wait=yes
After tih i receve Credit balans.

So, any command over USSD must be converted and then send. Then work with no problem. So how it look like R11e-LTE do conversation automaticly but Huawei card don't.

Hope this will help someone. I lost 5 hour trying solution
Hope it will be possibe in future that This card do the same like R11e-LTE

Happy you managed to solve the problem! USSD (Unstructured Supplementary Service Data) is a complete different service compared to SMS which is implemented with "/tool SMS". Have a look at chapter 4.16 and 4.17 in the AT Command Interface Specification for ME909s.

Yes. But intersting is that /tools sms send type=ussd phone-number=... work on R11e-LTE. Try many times. For Huawei need to be AT Command
Thanka for reply
