I know Yifanlu has been off, and I do see his point but to sort-of disagree with him I have to quote this:

Well, I didn't know any Amazon customer service rep can easily have access to my Personal Documents!!! Until, I called Amazon a few days ago and the CS could tell me everything about my personal documents!!!

Unwise to assume that Amazon can't see what's on their own servers. I really wouldn't store anything that you wouldn't want the world to see on a Cloud storage system.

Written like a non-member of the "we trust anything electronic" generation.

Same goes for any of those "free" file hosting services.
There has never been any such thing as a "free lunch".

To forstall a bunch of reply noise:
**NOT** even if you encrypt it.
That is only good for a warm and fuzzy feeling now, but no one can predict the technical future.

And mentioned only to trigger a paranoia attack in those readers subject to it:
Modern cell phones can often use encryption of their packets - -
but not all, and even those that can, don't always.
Older cell phones - forget it - you might just go the nearest rooftop and shout.
Plus -
the user does not have any indication if the over the air connection is encrypted or not.

Not very likely that communications over your 3G go through the Linux network stack.

The modem/radio cards can use a telephone number, a name, and/or a fixed IP address stored on your SIM card.
The modem/radio cards with chipsets that support a TCP/IP stack are rare.

AnyData is not all that forthcoming about their cards operational specifications, but my guess is that it is not one of the rare cardsets that directly support TCP/IP (and store a fixed IP address on your SIM card).

The AnyData card uses the Qualcomm qsc6270 modem/radio chip.
Qualcomm is not afraid that someone will use one of their devices.

The 4-page product brief shows a very busy little chip (see last page of brief).

You can get their 'AT command set' reference here, after you register for it:
AT Command Set
Edit-2016:
https://developer.qualcomm.com/downl...developers.pdf

Which of course will not mention any AnyData proprietary commands, and the AnyData card may not respond to the QualComm proprietary commands since it probably runs a custom firmware image.
But it is a start on knowing the command set of the modem/radio.

Also available free, to the public, the "Industry Standard" portion of the AT Command Set:
TS 27.007 and:
TS 27.005

Just in case anyone is interested in poking at their 3G modem.

A blast from the past, as found by Geekmaster.

The (public) command sets for the AnyData 3G card and for the general operation of SMS.

Thread bump'd because its information is once again of interest.

An SMS server - drives 1 to 64 modem/radios - GPLv2 so source is re-usable and contains the details of driving SMS over 3G modems:
