It is absolutely by design. The GSM standard recommends that, if encryption is disabled, the user be notified. This feature is called the "chiphering indicator". However, practically none of the available handsets do so.
- justinjlynn 10y agooops, "ciphering" ... also, even if the handset supports ciphering indication the SIM can disable it. Oh, and you're not permitted to reconfigure that part of the SIM either.
