Hi. I've got one of those free sim cards from O2 that give you 300 free texts a month. I've noticed that whenever I send a text (using the free texts, or even if its after the free texts have been used up), the reports always say pending. I've got a Nokia 7610. When I use my T-mobile chip, I don't have this problem, so I'm guessing I have to do something with the Sim. Anyone got any ideas on how I can fix this?
