2G Sim in a 3G phone?

declanmcc

Hi folks,

My sister is looking at unlocked Nokia 6680's on Ebay. She is currently on O2 contract (with a 2G sim). I know that using 3G Sims in 2G phones can cause possible damage ...... but can she use this 2G sim in a 3G phone like the Nokia 6680?

Thanks!

yes but she will have to ring the network to upgrade her sim so she can use 3g services
