Christian is on Virgin Mobile and every time he receives a text message, his data stops for about 30 seconds. Leo says this is just a disadvantage of CDMA technology, which is what Verizon and Sprint use. Since Virgin Mobile is on the Sprint network, he won't be able to do this. AT&T would allow him to do this though because it is a GSM network. The good news is that with the move to 4G/LTE, all carriers will be able to handle voice and data simultaneously.
