What is DUALSIMTM?
DUALSIMTM mobile phones are fitted with 2 SIM CARD slots allowing DUALSIMTM operation of the phone.
Mobile phones with DUALSIMTM Card capability have the advantage of allowing both SIM cards to be active simultaneously and allow calls to be received on either number, unlike adapters that require you to switch between phone numbers.
Normal GSM phones contain a single transceiver; DUALSIMTM phones have DUAL TRANSCEIVERS and display SIGNAL STRENGTHS for both networks. A phone with a single transceiver cannot be converted to simultaneous DUALSIMTM operation; at best you can only store both cards in an adaptor and manually switch between phones. The use of aftermarket adaptors in SINGLE transceiver phones could void the warranty of the phone and are not guaranteed to work on all phone models.
The inherent advantages of using DUALSIMTM mobile phones can be seen in two aspects:
- Firstly, you no longer need to carry two phones with you and monitor both handsets for calls or messages; most people would also need to undergo the time consuming process of replicating phone numbers and personal information onto each handset. DUALSIMTM phones integrate both sim cards phone listings into the built in phone book to create one seamless phone directory.
- Secondly, people can now have access to two separate phone lines on different networks; this allows you to conveniently access different network tariffs and charges without having to constantly physically change the sim cards inside the phone to take advantage of these offers. Eg If you have a SIM card with UNLIMITED TEXT MESSAGE offering and another with FREE CALLS offer.
