Products
concerned
This document applies
to : COM One MobiFlash GSM.
Issues general
1. Computer try to call but
nothing happens onto the phone screen.
Did you upgraded the
MobiFlash for GSM with the Loader tool? If yes did you choose the right phone?
If you're sure firmware is the right one (at *i) and cable plugged, see below how
to test cable and data subscription.
2. Computer dial, the number
dialled appears on phone screen but disappear after less 5 seconds.
Do you own GSM operator
Data/Fax subscription? (if yes you should see on the phone screen "Data
call..." or "Fax call").
Issues
fax
Computer dial, the number
dialled appears on phone screen but disappear after less 5 seconds.
- Do you own GSM operator
Data/Fax subscription? (if yes you should see on the phone screen "Data
call...").
- Try sending a fax to
another number of another company.
Fax transmission has started
then a problem appear.
- Is the transmission broken
every time or sometimes ?
- Try sending a fax to
another number. Is the problem the same?
- If available try another
driver from the fax software (if available select mode : Fax Class 2).
- Cellular network reception
quality might be too low. Retry from another location.
- If the software allow you
to get a trace of fax protocol exchanges, this can be useful to support.
Issues
data
Computer dial, the number
dialled appears on phone screen but disappear after 30-60 seconds.
Check if the data number
you're calling can receive analog calls or ISDN calls only. If this is a ISDN
only number, you'll have to set UDI mode to call it (AT +CBST=71,0,1).
How to
Test the cable and data/fax
subscription
Go into terminal mode (i.e.
Create a new connection and select "Use terminal window before
dialling"), then call the GSM phone data number with any device. The phone
will ring. If you see some "RING" messages into the software screen,
this mean cable and data number are ok.
Computer dial, the number
dialled appears on phone screen but disappear after 5 seconds.

Frequently
Asked Questions
Q : I'm trying to connect
(data or fax), the GSM phone seems to dial but nothing happen.
A : Check if you have a data subscription (optional for most of GSM providers).
You should get 3 GSM numbers with the data subscription (data / fax / voice).
Q : When dialling a data number the phone dials but after 5 to 20 sec
the phone hangs up.
1 - Check the quality of the GSM network (does the voice is okay?).
2 - Run terminal mode, enter AT*I to check if the firmware is matching with the
GSM phone.
3 - enter "AT S95=44" and try dialling the same number, then another
data number (ex: an internet access provider).
4 - If fail, enter "AT &F &W Z" to reinitialise the
MobiFlash, then try to dial a data number again.
Q : I can't receive any Fax or Data call by GSM (phone is ringing and
modem see no rings)
A : When you've subscribed to data/fax you've received 2 more phone numbers.
Currently you have 3 phone numbers: usual voice, fax reception, data reception.
- To receive a fax, you must be called on your specific GSM fax number.
- To receive a data call (i.e. call back), you must be called on your specific
GSM data number, so not the usual cellular voice number.
Q : Connection hang up after
dialling, I've already used the same PC/software/modem configuration for
cellular data/fax from another place and this was working.
A : We have seen situations in which even if the phone itself indicates a
strong signal, and voice calls are fine, data connections are unreliable. If
possible, try moving to a different area, preferably away from buildings and
towards a known cell site.
Thing to
know
When using GSM data avoid
moving. Moving from a GSM cell to another can be okay for voice (you might only
get some strange sounds for some seconds), but very harder for data (if there
are too much errors data connection will be closed).
