I purchased the Samsung y duos s6102 for traveling since it has 2 sim card slots. I had T-mobile service but I was always on EDGE so I figured the problem was the carrier so I switched to H20. The device is still on EDGE only with H20 but its compatible with 3G. Can someone help me configure this device for 3G. Thanks!
Sorry, you can't and not possible due to the hardware on your phone. The 3G frequency on that phone is 900/2100. From what I can dig up H2O uses 850/1900. So you're pretty much out of luck with that phone if you want to use 3G.
