Rsim 9 Pro can unlock ATT iphone 5 IOS 8.1.2 to T-mobile. No LTE, just Edge

Disclaimer: Boring Video. I had a spare Rsim 9 Pro card lying around and I had just bought an Iphone 5 running the latest IOS 8.1.2. I don't know why you would want to try using these RSIM/GPP cards since now in the US unlocking your iphone is legal. Anyways, for those interested in one method... here is what works for me: 1) Install iRoseTool on iphone safari browser from http://unlockpro.ru/nano4g.html the guy I bought the card from said to use this website instead but it didn't work: http://www.gevey.com.br/nano4g 2) I chose the 2nd option and then installed the "GPP 3to2" application to my phone. 3) Open "GPP 3to2" and select the first option "2g something" 4) Now insert your RSIM card with the sim card you want to unlock. 5) Restart your iphone 6) Upon booting the iphone will ask you "What iphone are you running?" I selected iphone 5. 7) Then it will ask you what carrier you are locked to. I chose "ATT" 8) Finally it says to restart.. so I restarted one more time. 9) after re-starting one more time... the iphone finally showed t-mobile after a minute or 2. 10) last step would be to install APN settings for this iphone. I used through the safari web browser: unlockit.co.nz That's it. All I get is phone calls, sms (imessage), and 2g internet. No 3g/lte... and also when I click voicemail it doesn work... I have to type in my phone number manually to get to voicemail.
