LONDON—Bluefish Technologies introduced a new SIM card facility that it said will allow several different network identities to be held on a single SIM card.
According to Bluefish, its multiple IMSI (international mobile subscriber identity) facility for SIM cards will appeal to network operators because it will allow them to ensure their roaming customers can use preferred networks anywhere. The SIMs can be configured automatically so the appropriate accounts activated as the subscriber roams in different areas or the subscriber can manually switch between accounts.
