❓ Help Tnt messaging

[shad Recto]

May problem po yung Sim ko when it comes in messaging. Lot of my contacts always reply na late na daw kung dumating yung mga message ko. Tapos kung minsan de padaw nila na re-recieve. And at my part. Same thing happens.
Any help po? And TY AND ADVANCE sa makaka tulong.
