Trying to activate the phone. The screen says removed sim card. The card is in but when you try to make a call the screen says "radio off" call not sent dial emergency #. Called Tag mobile, they said to try the sim card in another phone. We don't have another phone that takes the mini sim card. anyone with any ideas? This is a disabled client of mine, limited income, so has this phone and he needs it to work. Thanks to anyone who has an idea we could try.
