How should I change IMEI of GT-I9100?

Added by SomeThing toAskAbout 18 days ago

For some reason my cellular data jumping from there to there and (usually I have 2G; when I fast turn on and off "Airplane mode" then turn on "Cellular data" it works on H+ connectivity but no more 5 minutes or so) I'm guessing my network operator blocks me based on IMEI.

So if it not complicated or risky to change it, I will!
