Whats App ? App Question Please help?

[pri✍]

Do both your phone has sim card? So, people can WA you to either phone number, right? Think of WA as if you & your phone numbers & text messaging.

Or, you can install the WA on the second phone with that old sim card (that is originally in your old phone) inside it; this way I think, both phone will get the same WA message.

What actually do you want, different WA per phone number or the same WA for both?

Anyhow, as you have two phone, why don't you try that yourself?
