i tried to ring my boyfriend back in chitwan this morning from my cell phone using sdicard.com calling cards. i used three different ones (nepal, hola NY, and budget) and i just got busy signals on the first two and an "all lines are busy" message on the budget card. i am not sure if it matters if i am calling from a cellphone here or not (i don't have a landline ...) any help would be appreciate! really like to be able to call him soon!! thanks kiki
