Okay! You ought to obtain a dual sim card holder being made by 2-phones-in-1. This company is making dual sim card holders with auto switches so that you don?t have to do so by hand. You can visit the company?s site http://www.2-phones-in-1.com for other technical queries. Dual sim card holders are available that can be used with 3G compatible phones, will help in internet surfing and will work well with UMTS.
I am a dual sim card user. I have both the cards installed in the same phone. But I cannot switch from one sim to the other without manually switching one off. This is a real hassle while receiving calls. I am also on the look-out for a third generation (3G) compatible which will work well with UMTS and will also facilitate high speed internet surfing.
