i-SmartSim SIM Card Unlock Overlay Attachment for Nokia and Most Other Cell Phones (Yellow)

Pros: The device works good but when I tested the card in my phones. Unlocks 3G cards because in a nokia 6630 I can make video calls.
Also it works on a Sony Ericson T303 (not listed in the manufacturer information) but no 3G tested.

Cons: I need to cut the SIM card despite the manufacturer said that sometimes it nor necessary to cut. The difference between other similar products presented is this website is the fact that in this unlock card the chip is placed in the opposite side and it makes the application more complicated but the cut in the SIM card is easier, just a diagonal cut in the SIM card solves the problem.

Other: Happy with the product.

Pros: I have a T-Mobile Pulse locked by a local operator (the company policy) so I could not use a SIM card / number from other operators. I'll had go to the local cell phone service to get it unlocked and wait for a couple of days. With this attachment, I've solved the problem myself within a minute and cost me just a fraction of the price.
- great stuff
- works fine when attached properly
- I don't have to cut my sim as the phone have a plenty empty space bellow the battery, but it depends of the phone model

Cons: - It is a bit tricky to position the sim card properly on the contacts

Other: Save me a lot of time and a few bucks too. Very satisfied

Pros: Wery usefull. I had tryed to unlock my Nokia 7373, but with no luck, but after I bought this simcard, no problem. Easy to install/use. Just put it under youre own simcard, and it will work. Mine also worked on the internet....:-)

Cons: It is wery thin, so one has to be carefull with it. But of course, it cant be much thicker.

Other: Was wery usefull to me. This is much easyer, and cheeper, than unlocking the phone in a phone store......:-)
