Do T-Mobile prepaid phones still get to use the free T-mobile to T-mobile minutes or is it a different kind of service?
No. T-mobile prepaid don't get unlimited calling for T-mobile to T-mobile. You pay for the minutes you use whether you're calling from the same network service. For $10 you get 30 minutes. Text is $0.10 to send, $0.05 to receive Pictures are $0.25 to send or receive.411 and directory assistance is $1.79 per call plus airtime, For icons, wallpapers, ringtones, and games prices will vary per item.And you get nationwide coverage with long distance and roaming plus International calling and you get to access t-zone. That's much about it. Check out their gold rewards where you get 15% more minutes.
It's a different service, if you have prepay you use minutes every time you use your phone
It depends on which prepaid option you choose. The Pay by the Day option charges you $1 per day that you use the service, but charges nothing on days you do not use the service. That $1 includes unlimited T-Mobile to T-Mobile calls at any time during the day, and unlimited calls to any other number from 7 p.m. until 6:59 a.m. Other calls (basically, calls made to non-TMobile numbers between 7 a.m. and 6:59 p.m.) cost 10 cents a minute, and it costs 10 cents to send and 5 cents to receive a message. It is a really good plan-I just got it for my children because I wanted them to have a phone not for entertainment, but for security when I drop them off at Scouts or ball practice or such. I hope this helps!
