Yes

T-Mobile's native coverage is all 1900. Cingular uses both 850 & 1900. For
best nationwide coverage with either carrier it's best to have 850 because
T-Mobile now roams on a lot of 850 coverage from other carriers.
> Is prepaid the way to go for low usage?
Really is the best for low usage. Remember that in the US you pay the
airtime for both incoming and outgoing. You might want to look at this site:
http://www.cellguru.net/prepaid_compare.htm to compare prepaid plans. If you
get T-Mobile prepaid and put $100 on the account you become "Gold Rewards"
so the minutes get cheaper and last 365 days.

In the long run, it might be better to solve this problem independent of the
technology. Find the carrier & plan that works best for your needs and if
it's not GSM then save the 6100 for trips overseas.
