I have a client who noticed that she received all text messages on her iPhone but some were missing on her iPad. She had no idea why. This turned out to be an easy problem to fix, but first a little history.
Text messaging goes way back to the era of non-smart flip phones and little Nokia phones (remember when we all wanted the smallest phone possible), when normal text messaging rates applied. Text messages back then were all sent via the cellular network and your carrier – ATT, Verizon, Sprint – and they charged you a lot for texting. With smart phones, WiFi and the Internet, new way of texting that bypassed the cellular network cropped up such as iMessage, WhatsApp, etc.
Your iPhone is designed to use both the cellular network and the Internet so, by default, it receives iMessages and cellular text messages from non-iPhone users.
On the other hand, if you have an iPad without a cellular contract, you only have WiFi internet access and, therefore, only receive iMessages or other internet based texts.
Apple has a work around for this and that is text message forwarding. To set this up on your iPhone do the following:
1. Go to Settings.
2. Scroll down and select Messages.
3. Select Text Message Forwarding.
4. Turn on the iPad selection. (If you have a Mac, you can turn that on as well.)
That’s it! You will now receive all text messages on your iPad.
