I am currently on a plan with my brother and his wife with AT&T. I haven't had any issues except for the price, which isn't that bad. I pay $90/month and never go over my data, minutes, texts, etc...
However, I NEED something cheaper! I was thinking of switching to Ting, which I'm assuming most people have not heard of. My FI doesn't think I should switch to them because he thinks I will not be happy with their service since he has never heard of them. I am more open-minded though, plus Ting estimates my bill will be less than $50/month.
So, who do you have your phone service through? Are you happy with them? Any suggestions?
