I have a Moto G and am having trouble with messaging. Very short messages seem to be ok. I sent one longer than usual message and the person just received it after 2 weeks. I sent a pic taken with my phone to someone else and that also took 2 weeks for them to get it. Any suggestions?
try going to settings - more - Default SMS App you should see the word 'messaging' then go down to 'mobile networks' top of page should read 'Data Enabled' with check mark in box. Then go down to 'Network Mode and check to see if it on 3G
