I pay $230 a month for 5 phones, 3 of them are smart phones with unlimited data. All 5 have unlimited texting.
... why do you have 5 phones?
Edit: I barely use my phone. When I do, I'll top up £10 for free texts and internet a month. After that month, my provider has an offer where you can spend £5 and get a month free texts. I do this twice, and I get 3 months of free texts. I don't use the phone or the internet on it. Not a smart phone.
Although, I've not topped up since early November.
