Thank you BESTMAN gia tis apantisis.
After several Calls to CYta, i managed to make them work for me also.
I have Otenet, so no account for CYTA other than mobile.
APN: Cytanetforall.net
User: cytanetforall
Pass: (empty)
They work fine now. :)
Even though Netway settings seem to be faster.
Thanks again.
PS: CYTA has now offer for GPRS 1 month account 15CYP /50Mb / Month, so its better than paying by the MB at 2CYP each
