Sprint 9630 attempting to get on Digicel's 3G network

[dbda20]

So I live in Bermuda which has a Digicel provider and I bought my Tour 9630 in the states on a Sprint account. I've been back for a while using Digicel with my Tour fine but for some reason they claim that I can't use there 3G network??? The Tour 9630 is clearly a 3G capable phone so why can I not use Digicel's 3G network????

Hi,

The Tour doesn't do 3G on Digicel's GSM 1900 Band.
It supports Global 3G only on the 2100Mhz UMTS/HSDPA band.
