Good afternoon, I have
1. Mikrotik SXT LTE6 kit
2. Firmware version 7.16.1 (stable)
3. Build time 2024-10-10 14:03:32
4. Factory Software 7.15

I can't change IMEA on lte interface (lte1). Previously it was done as follows: Now these commands do not work in the WEB terminal (Mikrotik)
It's giving me an error:

Could you tell me how to change IMEI - without it SIM-card is not registered with provider.

Ask support ?

If current IMEI is not accepted by your provider, isn't it more logical to switch provider ?

Change IMEI code

# Query which mode
/interface lte at-chat lte1 input="AT*PROD\?"
"output: *PROD: 0" = production mode
"output: *PROD: 1" = non-production mode

# Disable LTE interface
/interface lte disable lte1

# Enter non-production mode
/interface lte at-chat lte1 input="AT*PROD=1"

# Power cycle LTE modem
/interface lte at-chat lte1 input="AT+reset"

# Confirm still in non-production mode
/interface lte at-chat lte1 input="AT*PROD\?"
"output: *PROD: 1"

# Display old IMEI
/interface lte at-chat lte1 input="AT*MRD_IMEI=R"

# Delete old IMEI
/interface lte at-chat lte1 input="AT*MRD_IMEI=D"

# Set new IMEI
/interface lte at-chat lte1 input="AT*MRD_IMEI=W,0101,11JAN1970,NEW_IMEI_NUMBER"

# Enter production mode
/interface lte at-chat lte1 input="AT*PROD=0"

# Power cycle LTE modem
/interface lte at-chat lte1 input="AT+reset"

# Confirm still in production mode
/interface lte at-chat lte1 input="AT*PROD\?"
"output: *PROD: 0"

# Display new IMEI
/interface lte at-chat lte1 input="AT*MRD_IMEI=R"

# Enable LTE interface
/interface lte enable lte1

It happens that "obscure" NMOs to try to lock customers into equipment that can only be sold by them through various restrictions. In those cases, you might have change the IMEI to one that unlocks the option to use equipment like Mikrotik's SXT LTE6.

Ask support ?

No, because it's only one provider who is normally working here. And he don't want to add my IMEI into his accept list.

Ask support ? - you mean support of Mikrotik ?

This I've also tried, this commands not worked.

Did you follow the guide? There are about 13 commands listed in the example, which one failed?
