Phone number for Whatsapp

@Kim Will do. Thanks!

You can actually use your Whatsapp account associated with your US number with any SIM card. Think of your phone number as more of a user ID for WhatsApp than an actual phone number.

Conversely, Kim is correct in that you could also wait until you get the local SIM and set up a WhatsApp account specific to that phone number.

I've done both and it kind of depends on what you want to do with it. If you want to make it easy to place WhatsApp calls with friends in the US, then it's probably easiest to do that with your US number, which they already have. If your intention is to use it to place calls to hotels and restaurants in Europe, then either phone number will work, but perhaps your preference is to give them a local phone number, the temporary one.

I am going to remove my earlier answer, because CWSocial's is more helpful !

Thank you both! Good to know it will work either way.

I use whatsapp all the time at home. It helpfully tells me if someone in my phone book is already on whatsapp (via their Nz phone numbers.) When Itravel and change sim/ph number what's app notices and asks if I want to change to the new phone number - the answer is always NO - so friends still know how to find me via whatsapp. My first name can be abreviated various ways (or not) so its important that I don't swap the ph no every few months
