Dual SIM Card Adapter With Back Case - iPhone 4s / 4

iPhone 4S

23rd April 2012

I was a bit skeptical about this product - would it work, was the case going to be naff, would it screw up my iPhone, etc.... I needn't have worried as this little bit of kit works brilliantly, is well built and looks rather elegant as well. I can also still fit the phone into my Logitech speaker cradle for charging. If you travel a lot (I live in Spain and work in London) you can have one sim for each country. When I am away from home, I switch networks once a day, check messages, etc. Although not a true "dual sim" phone, it works perfectly for what I need.

This is a very clever and well designed bit of kit. I am using it with a Three Sim (on the One Plan)for business and a GiffGaff Sim (which uses the O2 Network) for private calls. The case is very nice indeed and the adapter fits well inside it. It is a bit of a squeeze getting the adapter plus ribbon cable into the slot, but I managed it eventually. As others have pointed out, the adapter works fine without the need to jailbreak. My iPhone 4S has the latest firmware and as soon as I had installed the device, the option to switch numbers appeared in the Phone settings. I have had two minor problems. The first is that although the numbers switch OK, I can't get a full signal without re-booting the iPhone. For some reason, I only get one bar until I switch off the iPhone and restart it. The other problem (which isn't a problem with the adapter, but a problem with GiffGaff) is that the APN settings for GiffGaff have to be manually reset each time the switch is made. All in all, however, this is a brilliant product and well worth the money.
