I use to be able to receive pictures and group conversation verbiage and now its gone. I have a Moto Z phone. Should I uninstall and reinstall my SMS on my phone?
You can try updating your carrier profile by dialing ##update # on the phone keypad then try sending out a picture message first. That sometimes helps with MMS messaging. It worked for my dad. It's worth a try.
Check the APN on your phone, and make sure it's the same one your carrier uses. (Google <your carrier> apn [without the <>].) Or bring the phone to the carrier's store, if there is one, and ask them to check it.
