Possible To Use Vibrant With Prepaid T-Mobile Plan?

That's fine. Just be sure you download APNdroid from the market to disable network data, lest you want your prepaid balance to drain in a matter of minutes. WiFi will still work 100%.

 

Since the Vibrant is made for T-Mobile, it has all the right frequencies so there should be no problem. If you don't plan on doing a lot of talking, I suggest using the Pay As You Go plan, rather than a subscription. I also suggest buying a $100 refill because it'll give you 1000 minutes that won't expire for a whole year and you'll automatically be given Gold Reward status. I bought a $100 refill 8 months ago and I still have over $10 remaining. If I didn't do so much texting when I went to Canada or buy web daypasses, I'd have a lot more money left on my balance.

You will not automatically have access to the internet with a prepaid account so there is no need to disable data access unless you want to save on battery power. If you want data services with your prepaid account T-Mo offers several subscriptions, as well as a daypass for $1.49 which gives you unlimited data access for 24 hours.

T-Mobile Prepaid Plans

 

Great info guys. I had a question relating to this.
I have a vibrant and never use my data. So I am thinking about paying the $200 ETF to get out of my contract to save money over the long run with EM+ (had contract for 6 months) I text a lot, but don't talk. So I will look into the prepaid too.
Will EM+ try to steel internet and cost me extra?
What is the difference between the monthly plans and the EM+ plans?
Edit: After looking over my past bills, looks like the 1500 prepaid is best for me. (I even got myself a $100 credit from when they over charged me and I didn't notice)
Question: Picture messages use data, so if I turn off my data with the app, will the picture messages come up when I get in wifi and cost 1 point?

 

If all you do is text, T-Mobile has a great prepaid plan for you. They offer unlimited texting for $15 per month, calls are 10
