You can use iMessages, but it will only work for contacts with iPhones, iPads, iMacs or iPod Touches. You'll need to have your them start texting your email address instead of your phone number. This will start a new texting thread for each one in your texting app. You can then reply to these from your iPad or your iPhone. They received messages will go to both devices after you add your email address to iMessages on the iPad and the iPhone.
If you want it to work for Android and Blackberry contacts, you'll have to use a third party texting app on your iPad.
Lol you sure did Napoleon. Europa, what I'd really like to use is whatsapp for my ipad. I can use my cell phone number beings whatsapp isn't installed on my iPhone. Any suggestions on how to load it? Thanks
They still have to use a third party app for texting non-iDevices even if the iPad has a SIM card for cellular because that just gives you data off of WiFi rather than a phone number that works for cellular SMS, FaceTime or phone calls.
Just a suggestion but on your iPad, you can get a app called Text Plus. They will give you a phone number to use. Then load WhatsApp and use that phone number to register it. You'll get the confirmation message on TextPlus for the WhatsApp app, then can confirm on WhatsApp. I think this works. Europa..I defer to your ultimate wisdom.
