- Try sending a fax to another number. Is the problem the same?

- Perhaps network quality is too low. Try sending a fax from another location.

- If available try another driver from the fax software (Fax Class 2).

- If the software allow you to get a trace of fax protocol exchanges, this can be usefull to support.

Issues data

Computer dial, the number dialed appears on phone screen but disapear after 30-60 seconds.

Check if the data number you're calling can receive analog or only ISDN calls. If this is a ISDN only number, you'll have to set UDI mode.

How to

Test the cable and data subscription

Go into a terminal software (example: Windows HyperTerminal), 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 dialied appears on phone screen but disapear after 5 seconds.

Frequently Asked Questions

Q : Analog works fine, but GSM not.
A : Is the firmware of your MobiFlash able to support your GSM phone?
With MobiFlash check "at*i".
If not, you must upgrade the firmware with the software provided. This is explained into the documentation.

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.

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 hyperterminal, enter AT*I to check if the firmware is matching with the GSM phone.
3 - enter ATS95=44 and try dialling the same number, then another data number (ex: an internet access provider).
4 - If fail, enter "AT&F&WZ" 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 (ex: call back), you must be called on your specific GSM data 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.

Things to know

When using GSM data, avoid moving. Moving from a GSM cell to another is okay for voice, but very harder for data.
