Kontrolliere doch mal die folgenden Einstellungen:

Selecting a Frequency Band
Your iPAQ Pocket PC has an integrated GSM/GPRS feature that
supports four different frequency bands which allows for
international roaming. When traveling between countries and
wireless network operators, it may be necessary to change the
frequency bands of the GSM/GPRS connection settings. HP has
provided a selection feature that initiates an automatic search for
network frequency bands when your home bands are not
available. This automatic selection feature is the default setting
on your Pocket PC.
NOTE: Automatic band selection may not be available on all
models.
To change the frequency band manually:
1. From the Phone dialer pad, tap Tools > Options > Band.
2. Tap the square or circle next to one of the following items:
❏ Automatic (default setting)
❏ North America (850/1900)
❏ Europe, Asia (900/1800)
NOTE: Automatic band selection may not be available on all
models.
3. Tap OK.
Select the correct frequency band for the country or region you
are traveling through. To change back to automatic selection,
repeat step 1 and select Automatic.
