Dual Sim Holder

There are a couple of styles -- some slip in around the battery and some have a new battery cover that holds the SIMs. Do a search on ebay for "dual sim" and you'll see a bunch. They are tailored somewhat to the phone, but some of the ones for Nokia work for a range of models.

What you do is put the SIM sized adapter in the SIM holder. The adapter connects to a little circuit card that has two SIM holders on it. You put your two SIMs in there.

My first one for my Nokia 3100 was designed to sit on top of the battery. But the case was so tight I had to duct tape it to keep it closed. So I bought one that is a replacement battery cover (it sticks out a little more) with two SIM holders built in.

The batter cover has a switch. To switch SIMs you power off, slide the switch and power back on. The others you power off and the power back on right away and that switches SIMs. Supposedly there is a code you can enter on the keypad to "reboot" the phone (and switch SIMs) but I never got that to work.

Of course, only one SIM is active at a time. I usually have a national SIM and my Riiing SIM installed. I usually leave it on the national SIM unless I am going to make an international call.

It saves some switching of SIMs around (and I always worry about losing the SIM when its not in the phone).
