Noted that you’ve activated your MS Word on your iPhone using the same account, you should also be able to activate MS word on your iPad. In line with this, I would suggest contacting our Office 365 Support for further diagnostics. Contacting them will also help you check the affected account, identify why there’s no subscription found when activating it on the iPad and provide you the best possible recommendation.
