i have a galaxy s, duo core unlocked,GT-S7582L.... it says EDGE/GPRS quatri band, and HSPA tri band, which spec is the one i need to look at. What frequency is needed??

I think the package you are talking about is called the'Passport' package. I signed up for this for my trips to Jaco in Jan & Feb for Granada for $30 each month. It has unlimited text messaging, $1 min phone calls (as opposed to $2.50 i thinkif you are not on the plan) & free 120mb. The only problem I had was that when I was on wi-fi, I would turn cellular data/data roaming to rertreive my emails & get online. Then a few times I would forget to turn it off when I went walking around & a few email messages would download & I eventually exceeded my 120 mb data usage. Oh well, its a pretty good package to have if just going down for a week or so. The plan goes from the end of one month to the begining of the next you may have to pay for 2 months.

What company was your service with? Did you complete the contract (1 year-2 year)? If you did, they Wireless Provider may have to unlock the phone for you free. It's a new law that Obama signed recently.

This only applies to the big 4 (AT&T, Verizon, Sprint, and T-Mobile). Below is the link for AT&T, I'm sure the others have a similar setup.

3G data uses one of the standard 4 bands. 4G data might be different.
