Make sure the objects you're using are actually meant to be used for what you're doing. Otherwise, it's dangerous and you can cause damage to anything inside.
My finger nails are trimmed,

The only understanding I have of phone sex is that it's all verbal, unless you mean you're self pleasuring. In that case, it would depend on how you're doing this. If you're inserting your own fingers, it's possible you could just be aggravating it too much and cutting yourself. If you could provide more details, we could give more answers.
