does the $30 include free tmo to tmo
Nope
I am on prepaid $30 5GB 4G with 100mins talk time. Free T-Mobile to T-Mobile I believe is for family line - don't quote me on that. I scan thru the web still looking for a better alternative than GrooveIP. - 3rd party wifi Calling app\
Ultimately, with the $30 prepaid plan, there is no way to get "free" minutes whether it's TMo-to-TMo, WiFi Calling, Nights & Weekends, or anything like that. Your best bet to get ~$30 lines with a decent number of minutes is to have a
family value plan. They require contracts and do not have subsidized phones, but you can get 5 lines w/ 1k minutes shared, unlimited SMS, 2GB data for ~$25/line. A few examples with the Value plans (all w/ unlimited SMS, nights & weekends, tmo-to-tmo, and wifi calling):
1) 5x lines w/ 1k minutes, 2GB data: ~$25/line
2) 5x lines w/ unlimited minutes, 2GB data: ~$29/line
3) 5x lines w/ 1k minutes, unlimited data: ~$35/line
4) 5x lines w/ 1k minutes, 2x unlimited data and 3x 2GB data: ~$29/line <-- (this is what my family does)
5) 5x lines w/ unlimited minutes, unlimited data: ~$39/line
The trick with the Value plans is that you really need to need as many lines (up to 5) as possible for it to be so cheap. The way the plans are, 2 lines cost about the same as 5 lines. So if you only wanted 2 lines instead of 5, then those 5 scenarios would then be MUCH more expensive on a per-line basis.
