去外国要转sim card，可唔可以用番hk个电话黎用wtsapp?

(如果post错区请帮我del，唔好意思)

小弟黎紧会去外国读书，会系当地买电话卡黎用
请问我转左sim card之后可唔可以唔用新个个号码黎用wtsapp，而用番hk个号码呢？
因为我之前去旅行又系试过换左张当地买既sim card，一开wtsapp佢就要我更新个号码(记忆中佢系无得俾我拣更唔更新，但唔肯定)，结果我同人讲野都无人知我系边个
同埋有无方法可以知道自己contact list d号码系save系电话道定save系sim道？
我试过入setting去将sim card个d contact汇番入电话，但咁系咪就代表我电话宜家已经有晒个d contact，就算换左sim card都唔会唔见晒？
thanks

Yes. After you change the new SIM card and open Whatsapp for the first time, it will ask you whether you want to use the new phone number, as you noticed. But there is an option "NO" (may not be exact wording), remember to choose this.

As for the contacts - all contact info are stored on the phone, not SIM. Whatsapp can access the contacts information there, so no need to do anything.
