Incomplete message Samsung D900

[whiskychick]

I have a samsung D900 phone with a 1 gb memory card. I have 2 problems. 1) When receiving texts from a certain number on the same network (voda), if the texts are quite long ie. more than 1 page on the old nokia 3410 they always come through as "incomplete message" and no matter how long i leave the message it never eventually gets to me.It did on my nokia..... Most of the time but not always. I have "tested" this out with 2 other voda numbers , sending long texts but only happens with this certain contact. If my inbox is empty I can get the message but need to keep it constantly empty. Also when I use the option to transfer the full message from sim to phone memory it then appears broken Is the problem with my phone, my sim card or my contacts sim card........2nd problem is ...I have a large capacity memory card 1GB and it is so slow when looking through photos. Someone I know with a 250 mb card is able to flip through pictures and videos a lot faster. I have to wait 3 or 4 seconds between each one. Is the problem with my phone or my memory card.
