i phone settings

Novice II

I've run into a couple of phone glitches since switching to Visible and I'm not sure if they are related to my recent switch or not. Just tried to Facetime on my i phone with my son (who also has an iphone). Apparently when he called, it would not recognize my phone, so we ended up doing the call from my husband's phone. Also....when I text, my texts show up as blue sometimes and green at other times.

Ideas? Phone service and text functions seem to work fine.
