I own a multiImsi SIM that needs to interact with the device, and looks to be failing. Is TM2500 (or FMA120) really supporting SIM Toolkit app?

Thanks for your answer, could you please check which STK release protocol is supported by these 2 of your devices? Release 98 or 99?  I'm aware about some limitation with that multiIMSI card for Rel98 or older devices.

Thanks in advance!

Kindly create a VIP helpdesk query and state your requirements STK may require special firmware to enable this function.

Thanks, I will do so.

On the other hand, are there specific AT commands you advise to manage this STK support? Maybe a pre-configuration is needed?
