My mobile operator recently shut off 3G/UMTS and now my ec21eux does not register anymore.
Is this still latest firmware?
EC21EUXGAR08A04M1G_20.002.20.002
Could you send me the new file?

Thanks in advance

Ok, I found some recent document on the www which says EC21EUXGAR08A04M1G_20.002.20.002
is still the last version. The problem in my case seems to be the SIM card which is an MVNO SIM. I tried another non-MVNO SIM which registers properly to the same 4G network.
