⓮ Sending IMEI Number and Network Identification by SMS
Sometimes our customer service or your network operator may require this informa-
tion. You can send it via SMS to any phone number. (Please note that this only works
if your contract includes the sending of text messages and while your Opis desktop
mobile is connected to a network. For sake of simplicity you can also find the IMEI
number underneath your telephone)
Pick-up the receiver and dial:
Format:
*07#<destination number>*
Example:
to send IMEI and network identification to 01234567:
*07#01234567*
⇒ if the SMS was sent, the telephone rings once
⓯ Sending logging information to Opis Technology
Opis desktop mobiles support modern network technology worldwide. Due to the
complexity of this, there is a risk of problems occurring. This function helps us under-
stand a problem by providing us with relevant data for analysis (no personal informa-
tion or caller lists is transferred). Pick-up the receiver and dial:
Format:
*001*
to send the phone log to Opis Technology: *001*
Example:
⇒ if the log was sent, the telephone rings once
⓰ Forwarding text messages (SMS)
In line with its retro appearance, your Opis desktop mobile does not have a screen.
However, it is sometimes required to display text messages (eg when registering a new
SIM-card). For this purpose you can set up forwarding text messages to a number of
your choice. Pick-up the receiver and dial:
Format:
*002#<destination number>*
