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

Pros: Quite thin as an aluminium paper, just with the small chip on the border so you need to cut it. Good price for what it does.

Cons: to cut your Sim but not a problem in fact

Other: Do not think about it to try, as other customers said, it is cheap to have a try.

Pros: Confirmed that works on my Sony Ericsson T280i locked for Yoigo and now using a Simyo sim (in Spain). Tested for almost one month and no problem at the moment. I had some problems on the second day and almost gave up. Probably it was a network general problem as the company Simyo use vodafone/orange signal to work. Now appears Orange at the phone display but it is a Simyo card.

Cons: in fact it is not a problem cutting your sim card

Other: Buy it, do not hesitate. I also bought another xsim model in case of this not work. is not to much money for having your phone working free for choose the network/company you want.

Pros: Quite thin as an aluminium paper, just with the small chip on the border so you need to cut it. Good price for what it does.

Cons: I´m testing this on an simple SonyEricsson t280i in Spain. It is locked for YOIGO, and now I have a SIMYO card. It worked as soon as I puted with my sim card but at the next day when I checked again was as "network not available". I put it out and in again and shown me network for couple seconds and then no network again. I tried again twice and I gave up. After 2 days I checked it again and it is now working. I need to wait a little bit more to confirm its usefull, but it´s ok for me.

Other: none

Pros: Just unlocked an HTC Wings (Hera110) successfully today. Am in Mauritius and could not hove access to the Orange network but the Chilli network worked fine. The greedy unlockers will not get my money

Cons: My orange Sim card got useless today. Will contact the provider on Monday. the material is indeed fragile and the diverse manipulations with my orange Sim Card bended it over. However I eventually accessed the Chilli network today.

Other: If you want to unlock an HTC for cheap go for it.
