If you are responding to a text message then the 5 texts aren't chargeable

The 5 text are usually a few days after you purchase a phone & are free but it's saying you will be charged it sounds fishy

Your phone will always warn you about a potential charge because the texts go to a shortcode number of which some are used as premium rate texts, but the texts to o2 are free.
