Is R2C of RC7611 still available?

I understand that R2C is no longer supported by the RC7630.
Is the RC7611 still R2C enabled?
And is this only possible when using Sierra wireless USIM (connectivity)?
Or can I also use Verizon/AT&T/T-MO/Sprint?

are you able to read the esim after switching it by AT!UIMS?

I inquired whether Sierra wireless’s (Semtech) R2C solution was still available for the RC7611.
Also, will it be possible to use major carrier lines such as AT&T/Verzion/T-MO using the R2C solution? Or is only Sierra USIM available?

I think you better get in touch with local FAE

But I can see here has related information:
