Can you check ur children's text messages on their t-mobile phones?
poor kid lol. u can only check the message if you look in there phone. but they may be deleted. on the bill if you have detailed billing it will show you the number that was texted or that texted them :)
Well you can check the balance with #674#. And if you actually want to read them you can do so online. Or you can request that tmobile send them to you over email or us mail. Hope this helps when calling ask to speak with a technical support representative.
