Hello,
I am trying to read an abbreviated dialing number in EF-ADN. Does
anyone know how to do that using AT commands.

Thanks

There may be more than one way to do this, depending on which
"AT" commands and command arguments your device supports (many
are optional).

Select FDN as the active phonebook with

AT+CPBS="FD"

And then use "AT+CPBR" to read the entries.

You should also be able to direct-dial from any phonebook. See
clause 6.3 of 3GPP 27.007 for details.

You may also be able to bring out the heavy guns to read and/or
write to EF-ADN (and other SIM elementary files) using
"AT+CRSM" and SIM address "6F3B" (see 3GPP 31.102).

Note that "EF-ADN" above should read "EF-FDN". EF-ADN is quite
a different phonebook from EF-FDN (a distinct SIM file).

By the way, to select EF_ADN (rather than EF_FDN) as the active
phonebook, use

AT+CPBS="SM"

Then can then use "AT+CPBR" to read entries from it. "AT+CPBF"
might also be helpful to find the entry you want quickly.

These are 3GPP 27.007 commands.
