Quick query -I had a user who was travelling on a train this morning and said her Blackberry device wasn't receiving any email, however she was able to send text messages and make phonecalls on it. The Battery on the device was fine.
Is there any explanation to this? Does the data use a seperate 'network' than the phone/sms?
Also - she says that she was able to connect her laptop to the WiFI on the train?

Do a battery pull while the phone is on.
Then note what the signal type shows edge, EDGE, evdo, EVDO etc.
Bold usually means data.
Als have seen data plans removed from accounts for unknown reasons.

Thanks for responding...
The user is back in a city now and everything works fine, I was just trying to find an explanation as to why this happened?
I don't know much about mobile networks, so you'll have to bear with me
Is it concievable for the phone/text part to be working, but the actual Blackberry email functionality not, due to service coverage? Or if the phone works, should the data part as well?

Phone / text are on same band.
Data side is on different band
So it is possible the phone/text works and no data, happens with data outages at times too.
Possible she has WIFI and it connected to it but could not browse?

Thanks knottyrope....you don't know what those bands are called do you, so I can check on internet and read up on them?
Would you say that it's more likely for the data band to be out of service than the phone/text band? Is one type of band more restricted in terms of coverage than the other? For instance, if she was on a train in a remote area, the phone band would be weak but able to work, but the data band just too weak?

Knot knowing the bands
Voice always works but data can be spotty in some areas
