Hi Barbara When I had a Nokia 3310 I used to use a dual sim holder which worked fine. you had to switch the phone off, flick the switch on the holder to the left or right depending on where it was before and put the phone back on in order to get to your other simcard. However, I don't know whether it is possible to get these for the newer phones. If it is then I don't think it would be difficult to fit. I certainly didn't need sighted help fitting mine with the 3310. I hope this helps. Pritesh Pritesh and Alpa Thakore E-mail: alprit@xxxxxxxxxxxx Skype name: alprit5 MSN: pritalpa@xxxxxxxxxxx
