Super X-SIM III Universal Phone Operator Network SIM Card Unlock Attachment

Pros: Very easy to use. Worked for me on my Samsung 740sc Softbank.The package is very good actually. The chip is really very thiny, there is no problem to insert both the chip and SIM card into cellphones SIM dock.

Cons: You have to cut your SIM card to use it. Nothing really difficult though.

Other: It worked for me. You never know if it will work on another cellphone model, but it's so cheap that it's easy to give a try.

Pros: - Easy to use and install, not need technichal knowledge for install, just a low cut on the original chip
-Facil de usar e instalar, no se necesita conocimiento tecnico para instalarlo, solo un pekeño corte en el chip original

Cons: - its very small and flexible, because that is delicated
- es muy flexible, por eso es muy delicado
- use that with a lot of caution or may be broken
- usarlo con precaucion porque puede romperse

Other: - great product just need some cautiones ^^
- gran producto solo se necesitan algunas precauciones ^^

Pros: It worked fine with a Motorola Razr V3 + a Dummy SIM card.
Just enter between the SIM card and the Phone, turn it ON, and it works.

Cons: Build quality is somehow cheap (Careful when you manipulate it),
and one of the parts is thicker so it's hard to enter in the slot with a SIM card without breaking anything.

Other: If your cellphone has been blocked by crooks (a company) who does not want you to be able to change company, this is the perfect item. You don't have to pay anyone to unlock your own property.

Pros: The price is cheap, if you get it to work with your celular phone... In my case I have tryed to unlock a nokia 3120 classic but I did not success... it just do not work on it.

Cons: It does not work with nokia 3120c-1b (classic).. this celular phone is a couple of years old but still it did not get unlocked by this sim card. It just shows the message "no sim card found"

Other: It does not work with nokia 3120c-1b (classic).. I hope this is usefull for someone else wishing to unlock one of these cell phones...

Pros: easy to install. This sim card is very easy to install. It unlocked my Samsung cell phone right away. I will tell somebody about this unlocked sim card. And the price very cheap.

Cons: There are no cons about this product. This product was worth its price.

Other: In conclusion, I totally recommend this product to anyone wanting an easy install for a low price! If you have an unlocked sim card for iphone: it's great!
