Prepaid Mobiles

and u wanna call someone in germany, and u use the card, will it charge ur cell phone?

I have a prepaid sim card from the t mobile company and im going to mexico for a while, so if i want to call from mexico to the U.S will it work or will it charge me extra or it wont work at all ? also will it be free if its t mobile to t mobile?

I’m looking at pre-paid phones from T-mobile and planning to buy one, but I don’t know if i should buy the T-Mobile SIM Card Activation Kit? Do I necessarily need it, or does the phone already include this?

ill be calling from my mobile phone to her mobile phone…she’s in australia, im in the u.s. there’s so many phone cards out there though, especially that i’ve seen online.

does anyone have any personal experience with any phone cards or prepaid cards or anything that they could recommend? something that’s affordable yet has a good quality connection, or which ones to stay away from.

thanks!
