Security

Why do I have to choose a good main password?

A simple password is easy to guess. If your phone gets into hands of your adversary, they will try several millions typical words and their combinations against your encrypted data, with use of a computer. It is important to choose the main password (passphrase) carefully, so that it cannot be determined in such an attack.

Why does the "SMS 007" system use AES cipher?

AES cipher has been extensively tested by scientists and therefore can be considered reliable. Moreover, it is very fast and does not demand huge memory, which is very advantageous in small devices like phones. Finally, there is no software patent pending on AES, and will never be.
If you want to use other ciphers than AES in your "SMS 007", please consider the following possibility.

What if I lose/forget my password?

In this case, all data saved in the phone are gone! There is no way how to retrieve them without knowledge of the password. The encrypted data will still be in the phone, but you will not be able to access them, unless you find your password again.

Devices

What kind of phone do I need?

To run SMS 007, one needs a phone supporting Java MIDP-2.0 and so-called WMA API. Older Java phones, which support only MIDP-1.0, cannot run the system.
The main difference between MIDP-1.0 and MIDP-2.0 is the ability of a Java application to be "woken up" by a received encrypted SMS. Older phones do not have this option, and they would discard the incoming messages. That is why user with older MIDP-1.0 phone would not receive much of the messages.
A partial list of MIDP-2.0 phones can be found at this website, but it is not complete. If you want to check whether your phone will support "SMS 007", please contact us.

Which phone would you recommend to me?

We have very positive experience with Nokia 6230 and 6230i. Also other Nokia phones seem to provide a smooth performance.
In Siemens phones, the newer model - the better. Older models have some problems concerning "violent" closing of the application.
Performance of Motorolas is not really good. Motorola phones seem to suffer from slow processors and lots of subtle bugs in firmware. We cannot guarantee a long-term successful service in Motorola device.
Samsung series SGH-Vxxx will not support SMS 007, since it lacks so-called WMA API. Samsung SGH-D500 and similar will, but they seem to have some bugs in firmware as well. For example, the incoming message may be cloned into several identical copies on Samsung SGH-D500.

Installation and use

Do I have to have GPRS activated?

You need GPRS to install SMS 007, but not for further use.
You can install the system using a SIM card different from the one that you'll be using. That means that you do not have to have GPRS activated on your own SIM card. It only must be activated on the card which will be used for installation.

Can you help me installing SMS 007?

Installation of the system is part of our service in Profi and Special variants. Otherwise, you must be able to install SMS 007 yourself.

Can I use SMS 007 abroad (when roaming)?

Yes. As long as you can send normal SMS, you can use SMS 007 as well.
