    My edge is not working with my univeral sim I have done every thing turned on data roaming, entered wap.voicestream.com, taken out the sim and put it in different phone then back in iphone 3g. I have USA t-mobile t-zones and it wont even show the edge icon only lets me make calls and connect to wifi. Can you help me with this problem?

    I bought an iPhone 3G two weeks back as I was in US. I purchased the Universal SIM card in US as well. I have international SIM card and data roaming. As per the instruction on this web site I put both Universal SIM and my International SIM card together…My iPhone was unlocked and it worked for around 15 minutes….I got international roaming through T-Mobile, and could call internationally…then suddenly I got no service..I switched off/on the iPhone several times, and still didn’t get the network..Then I put back my own SIM card into my original cell phone, and I got the message “Your SIM card is corrupt. Please contact your provider”. It seems the Universal SIM card corrupted/damaged my original SIM card. Now neither my iPhone nor my own cell phone work!

    I have tested your ship on NOKIA and LG fones. The chip unlock both phones but the signal goes way after 5 seconds and don’t come back anymore. Am I doing anything wrong? Do I have to set up the cellphone to accept the signal? Do I have to download up to date software from your site? there is a special software for basics phones e other for Iphone? What version should I download for basic phones or shold I download the V600 for all? Is the V600 the latest version? I will receive the Pkey Card reader next Week . Please help me out…..

    I bought the universal sim card and had installed 5 days ago and it was working great. Today it said no service, so I reset the phone many times and still no service. I removed the sim card and then re- installed it and know it says no sim. If anyone knows what’s going on please help me. Thanks

    seems there is some hardware failure in your Univertsal-SIM. You can try to resolder the microchip onto the FPC and then clean the contacts of your Universal-SIM.
