EC25 supported bands list

Good afternoon.

What AT command can I use to see all supported bands for a modem EC25 and EG06?

I am writing a universal firmware to work with several modem options.

Hi Sir

Could you please check your specific EC25 Series? EC25-EU, EC25-E? Much appreciation

Yes, I can find all the frequencies for each modem variant. I have the necessary documentation. My question is different. Is there an AT command that returns a list of frequencies supported by the modem? In my case, the modems may be different and I would not like to store a database for all variants.
