Allphones are selling the Huawei Deuce U8520 Dual SIM Android Smart Phone for under $300. This device has two slots for SIM cards, allowing the phone to operate with two telephone numbers from two different phone companies simultaneously. This feature is popular in parts of the world where there are many phone companies competing. This could also be useful to have separate personal and business numbers available on one phone. One catch is that only one of the SIM cards can use 3G, the other is limited to the GSM network.
I would be interested to see if I can put my Virgin Broadband SIM card into the 3G socket, along with the Vodafone SIM into the 2G socket. The idea would be to use the GSM phone for ordinary calls and the 3G for data. While it is possible to get Internet access via a phone account, the prices are very high compared to broadband only plans. The phone would then act as a WiFi hub to provide Internet access to my laptop and TiVo. Has anyone tried this? The discussion in the Whirlpool Forum suggests it should be possible.
