Problem with TK 303b commands

Eddiea year ago

Hello everyone, I hope you are well,
I am having a problem with a TK 303b device
When trying to send a command, specifically
ArmAlarm

When sending this command through the web interface, I don't know if it is being sent, since I am verifying the command through an SMS check123456, the arm status appears as: OFF

I do not have my device connected to a car, since I am carrying out tests

My question is, does the change have to be reflected in check123456, or is the action only executed on the device?

On the other hand, how can I verify that the commands are sent or if the problem is my device?
I have tried to factory reset my device with begin123456 and reset123456, but I still cannot process

I have also changed my protocol 123456 to 18 out, to be able to execute commands from other services, but I still cannot solve this,

Regards
