2 Treo 750
Taking advantage of fast broadband speeds
You must have a 3G SIM card in your Treo 750 to take advantage of fast
broadband speeds. To determine if you have a 3G SIM card, look for “3G” to
the left of the gold connector on the back of the card.
If you do not have a 3G SIM card, please visit your local AT&T retail store to
swap your existing SIM card for a 3G SIM card. There is no charge to
exchange your SIM card for a 3G SIM card.
