You can still buy data plans as a Go Phone user, but no longer if your rate plan is either the 10 cents/minute or $2 day unlimited plan. You have to change your rate plan to either the $25 a month for 250 voice minutes and unlimited texts, or the $50 per month unlimited, in order to purchase or renew a data plan. Which really sucks. I'm on a very tight budget, and don't use my phone often enough to need the $25 a month plan. I'm on the $2 day unlimited, and use 3G only occaisonally. It was nice to have when wifi wasn't available. But, I don't use it enough to step up to the $25 plan. So, I intend to do without 3G, or possibly switch to an alternative carrier.
