So I went to the Sprint store today and played with the one max.the spark icon spins only when using data and it looks like it shows LTE signal not 3G.
So if your in a roaming area with a tri band phone and your next to a clear site that if/has the spark upgrade you will not get LTE because you don't have a Sprint 3G csfb signal.
I changed back my prl because I was going out for my birthday and lo and behold they fixed the problem with the tower so now I get Sprint service again.
I have a Corporate personal account so I trust the corporate cs I also talked with her manager and she gave me extra 300 minutes to use. Also when I leave my area I put it back to a Sprint prl. I only use it when I'm home.
I have told them I'm using a Verizon prl till they fix it and they were fine with it. Once it's fixed I will have no problems so I'm not going to leave just because of this one thing that will get fixed.
I'm having the same problem my phone is connected but has no service it's been going on for over two months.they replaced my phone but it didn't help. I now just use a Verizon prl.
This has been going on for almost a month.I put in a network ticket if anybody wants to guess what is going on. My phone connects but doesn't have service http://db.tt/65iHUZAh
