iPhone 4s
Easy to set up and use
I was a bit sceptical about this but it does work perfectly and I even managed to get the original cover I was using back on without any problems, there is just a bit of a bump at the back. Best method of changing network is to select the Sim that you want to use and then reboot the phone, its takes a few minutes to find the network but once you have it there is no loss of quality or signal. Highly recommended.

iPhone 4S
Works just as expected
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 Product Rocks!!
This product is just perfect for my needs. It allows me to carry 1 phone but with access to 2 numbers. Alright, it wont allow you to use both numbers together but you can switch over to the other number without powering the phone down and it takes about 8-12 seconds to do. Fantastic!!

Almost perfect ..
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.

This is a great bit of kit!
Thanks MobileFun I have now used the duel sim adapter a number of times since i have purchased it and it's brilliant. It can be a little low picking up the network when changing over but when it does there's no problem. Three friends have already purchased it from my recommendation. Rapid fire delivery as well

Great service and quick delivery. Thought the case was a bit cheapy and could have been a nicer/better quality design, but it does the job nicely. Will use again!

Not used this properly as I'm planning on taking it to the states with me and buying a pay as you go sim but tested it and it seems to work no problem.

The dual sim works just fine. I've used her 3 weeks now and no problem. You just have to set it to the other sim card in the sim applications menu and you are good to go. Note that the message at the top left of your iPhone reads No Sim for about 5 secs while it searches for network. *****I ordered on a Friday nite and mobilefun delivered first thing Monday morn. Five stars.
