Who knows why I can't watch the long messages I received together?

Excuse me, is there something wrong with my mobile phone settings? Don't answer until you see it clearly. Thank you for your cooperation. Can you tell me more about the gray sky? Give it to me tomorrow: I know what you said. The key is to send the same message to that mobile phone with Samsung and MOTO's mobile phones, and watch it together! Is there something wrong with my mobile phone settings?

Supplementary note: My mobile phone is NOKIA6300, and the phone model of the other party is Nokia N95. Little darling: You haven't understood the meaning of the question. I don't know if you have experienced it. The received long messages can be read together. I asked why I couldn't watch the long message I sent together. I'm dizzy ~ ~ Would you please read my question before you answer? Supplement: Thank you, although your answers are basically not helpful to me, I also know the answer to this question, because I use Unicom mobile phone and my friend uses mobile phone, so I can't combine reading. I can only choose two friends who answered in detail as answers, thank you.
