If your smartphone normally connects to a CDMA network and your smartphone supports international roaming,
you might need to get a SIM card that is set up for international roaming from your wireless service provider. Your
phone number stays the same when you travel internationally.
For more information about roaming and roaming fees, contact your wireless service provider.
