iPad and iPhone

I have an account with Verizon and I purchased an iPad. The iPad was assigned a phone number and I UNDERSTAND that it’s not used for making and receiving calls…my issue is that once I put the iPad on my iCloud, I began receiving text messages to my iPhone and iPad. I don’t want that to happen. I’ve turned off iMessage and FaceTime on my iPad and I’m still getting iMessages. I have a MacBook and an iMac as well and I don’t have that issue with either of those devices. Is there anyway possible to completely prevent my iPad from receiving messages that my iPhone is getting?
