I've been with Virgin for several years, no real issues, $25/mo plan. My phone is getting old, Moto Triumph flashed with Paranoidandroid ROM, I'm looking to upgrade. Budget for new/use phone ~$150. If I upgrade on VM my cost goes to $35/mo. Had pretty much decided on a used S3 and ting, I'm a low minutes user moderate data user so my monthly cost would be about the same, $25. Then began seriously looking at the LG optimus G, at the moment that is my phone of choice, but found Sprint around here is only 3G. So considered using a used S3 that would work on the T-mobile $30/mo plan. Doing some reading it looks like roaming might be an issue. I pretty much stay in my area but do travel from time to time. With Virgin it has not been an issue, I live in Mid-MI and travel to Chicago with zero coverage issues. Same with Florida Not sure what to do. The three phones I'm interested in are the LG optimus G, S3, and the HTC 4G LTE. Of these only the S3 can be had in a version that would work with T-M. Low monthly cost is primary issue, $35 is my limit. Thoughts? Suggestions?
