Why isnt my phome recieving texts half the time?

[AC Question]

Ive had my lg stylo for only about 4 months and it wont revieve texts half the time. It can send texts no problem nut shortly after i got it it stopped recieving some texts ive tried restarting my phone and that does nothing. Ill be having a conversation with someone or not even texting them at all and all of a sudden i wont get a response back even though they sent one. It happens with every number no matter where I am so I know its not a service issue. Recently I havent been abled to receive any multimedia messages such as pictures or group messages although I can send those too.
