I'm wondering if i can pay for a $25 gophone plan (unlimited text, 1c/10kb, 200+ calling minutes) on an unlocked samsung focus and a $25 data package (2gb), will that work? all i am wanting is unlimited text and enough data.
Or can i use my current $50 GoPhone plan (unlimited text&talk, 100 mb, i think) with my smartphone?
You can use your Focus on either of the plans you're wanting to use. For your current $50/monthly plan, as long as you have a separate data package such as the 100MB package, that would work absolutely fine. I assume that you already know that smartphones cannot take advantage of the unlimited data portion of the $50 plan.
You could also use your Focus on the $25/monthly plan, but there is not a 2GB offered plan on prepaid service for data, but a $25 500MB data package instead.
