Yes, she did say that. But notice she couldn't have limited her phone to only the sim, but also entered numbers into the phone memory and eliminated some. This is easy to see by looking at both docs. The final entry on the Sim card is Det. Melich, entry 97. It is also the final entry on the phone memory but is 167, a difference of 70 numbers. I don't own a cell or sim card, so maybe someone knows a reasonable explanation that eliminates the possibility that there is another phone with a different memory bank.
Looking at both docs, it appears to me that the phone memory has the sim card loaded twice, the first half being where she did some editing, deleting and changing names. Evidence of this is shown through Ricardo being called boyfriendizzle in entry 44 and Ricardo in entry 137. The whole bottom half matches the Sim card entries. So I would assume the card was removed and put back in, thus bringing in the sim memory a 2nd time. She made changes to the top half, leading me to believe, on the Nokoia, the top half was the recent numbers used, perhaps replacing some that were obsolete, and new ones added would be at the bottom. Correct me if this isn't the way it would work. I draw this conclusion from the last half of the phone memory being identical to the sim card. If she were scrolling through to find a number, didn't like the way one was written or didn't want it there, she would change it, replace it or delete it. Now, we know when Ricardo was still her boyfriendizzle and when that was likely changed.
I also agree that no calls to anyone named Zenaida has been identified. But that doesn't eliminate the possibility that one of the yet unidentified numbers isn't this person or that the person's name isn't really Zenaida. No one seem to have a problem believing she has lied, for obvious reasons. But there are pieces of truth woven in.
