Q: as i want to upload a 700 mobile numbers to my iphone to create a group for whatsapp messaging

Hi there mohamadfromchennai!

I understand that you'd like to add 700 numbers onto your iPhone so you can create a group for WhatsApp. If you have a computer with contacts on it already, you can try syncing them to your iPhone with iTunes. To get more information on syncing, please visit this knowledgebase support article from Appel: Sync your iPhone, iPad, or iPod touch with iTunes on your computer using USB - Apple Support. I would think that for iTunes to recognize the "contacts" it will have to be in a compatible file, like a vCard - If I'm correct.

I hope this information helps you. I've tried to provide you the most accurate information I know as well as possible, but if I've provided any inaccurate information I would like to go ahead and apoligize about that in advance.

Hopefully this helps you as well.

Cheers!

You sync your iPhone to a computer, I presume? Add these 700 numbers to your contacts app on the computer, create groups as needed, then sync the updated contacts to your iPhone via iTunes or iCloud.
