Motorola RAZR V3

i did do a quick search and i didn't see this question anywhere ,so i'll just ask . I used to have an LG C1500 and i hated it so recently (yesterday) i bought a silver razrV3 (loving it so far) my only problem is that my old saved text messages don't seem to show up in my new phone , they're there when i put my sim card in my old phone but only the most recent 7 show up in the new one . Does anyone know how (or have any little tricks i can try) to make all my texts show up in the new phone?

any help is much appreciated 😁
