GSM Information on roaming in the USA
If you want to use
GSM within the United States, please read the following:
|GSM is a worldwide digital signaling standard
that is extremely popular in many parts of the world. However in the
only covers certain cities and few rural areas. TDMA and CDMA digital
with analog for rural areas are the 2 standards that the national
carriers like AT&T and Sprint are using.
|North American GSM networks all use the
1900MHz waveband for their air interface, while European and Asian networks use either
900MHz or 1800MHz. This requires the user to have a multi-network
phone or obtain a 1900MHz phone to place their SIM card. Tech-Go can
rent or sell you a USA GSM phone to use with your current international SIM card - click
|For those cities in the USA that have GSM, roaming agreements are not always in place with countries abroad.
You should determine which USA GSM carrier serves the cities you would like
to use your service and verify your international GSM carrier has roaming
|If you verify service, please obtain usage
rates directly from your international carrier. You will probably pay between
$2.00 and $3.50 per minute to roam/use the
phone in the US. By the way, if you travel to a non-GSM city or most
rural areas your
phone won't have access to the GSM network.
|Another option is to rent a USA-based Tech-Go digital phone and
have it shipped to you when you arrive in the United States. By the way,
the rates we offer are cheaper than you would pay your carrier to roam here in
the US ($.50 to $1.25 per minute for US usage).
