Yog hais tias koj nyob nraum siv ib ntsiav tshuaj nrog 3G thiab nyob rau tib lub sij hawm yuav tawm mus rau ko taw, ces cov ntaub ntawv yuav tsum tau muab rau koj ntaus ntawv nrog ib tug me ntsis ntau dua tus nqi tshaj nyob rau hauv lub yav dhau los cov ntaub ntawv - 384 kbit ib ob. Pom zoo, qhov no yog ib tug me ntsis, tab sis rau caij saum nthwv dej yog txaus. Ib tug yeej zoo rau kev ntsuam xyuas yog dab tsi 3G nyob rau hauv cov ntsiav tshuaj, koj ua tau, yog tias koj tsis khiav, tsis txhob taug kev, thiab yog nyob ruaj ruaj. Thiab ces koj neeg teb xov tooj yuav tsum thov koj hauv internet mus txog 2 megabits ib ob.
peb xav kom teb nyob rau hauv no tsab xov xwm no rau cov nqe lus nug ntawm yog dab tsi nyob rau hauv lub 3G ntsiav tshuaj.
