to recharge AldiTalk:

enter: *104* 16-digit recharge code # then press the call button
Example: *104*1234567890123456#

*104*[recharge code]#

Edit: didn't notice Globetrotter's reply above!

thanks both guys!
has anyone tried this (*104*recharge code#) while abroad in roaming?

another question, when I receive my aldi sim, will I have first to register it online in order the sim to be activated OR sim is activated by just getting a network signal for the 1st time?

Yes I did it in roaming :)

You MUST activate it online first. You need to enter a German Address for that. Your sim should work within 30 minutes of registering it.

thank you, I did that.
for the "EU INTERNET PAKKET 60" what is the apn? internet.eplus.de ?

Yes, the same as you use in Germany.

i can confirm that recharge for aldi mobiles from this eshop: Recharge your mobile with works properly using eplus vouchers! credit is sent directly to the sim after few seconds!

*minumum value of recharge is 10euro! they accept paypal, creditcard e.t.c.

how can the mailbox of alditalk be deactivated?

Call 9911, configure mailbox (choose your PIN, etc) then choose 3 → 2 → 8 (see http://www.alditalk.de/talk/download...sanleitung.pdf page 10)

9911 is not accessible while abroad in roaming... at least in where I am/
