I've figured since there is a defectors why not make a positive VM thread as well. Basically post here if your VM experience has improved (ex speeds, call quality, etc.) or they've done something nice for you as a customer (ex gave you a discount, promo code, etc.)
When I got T-Mobile Monthly 4G back in January, I've put my Virgin Mobile account on hold and decided to add money to it every 60 days. The reason I didn't sell it was, because it's still cheap and has a bigger 3G Network. When I go out of town with T-Mobile it doesn't take long for the EDGE (2G) symbol to appear. Anyway, today I received a letter from VM which said "Service Notification". Before I opened the envelope I thought that they probably send me a message about their planned data cap or maybe they were about to terminate my account for not making any payments since January.
When I opened the envelope I was pleasantly surprised. VM said that I didn't make any payments in a while and to "help me financially" they offered $10 credit if I added at least $15 to my VM account, making the total $25. I've thought to myself "Why not?" and I added the money.
I naturally wanted to test out the speeds and I wasn't impressed when I got 100 kbps down with 500+ latency, but I didn't give up there. I ran a "network refresh app" and got speeds over 1 mbps. I thought that maybe it was a glitch but I still kept getting pretty high speeds. They would drop to 300 kbps every now and then but were much better than what they used to be before.
Finally I checked out Sprint's tower upgrade map and indeed a nearby cell tower had a data speed upgrade. Overall I got speeds over 1mbps more times in a row than I ever did and they were done during times when normally I would get crappy speeds (5 to 8p.m.) . If this was only a small tower upgrade and I saw a major speed change then the speeds should really be amazing once Network Vision rolls out in NYC.
I previously believed that VM cared the least about people on the $25 plan and they would love to have us off that plan, but it seems that it's not the case, at least in my situation.
I can only hope that these speeds will continue to get better, especially when that data cap hits.
BTW, it still seems that all the data is being transferred via a server in Kansas like it was before.
Just ran two more speed tests, this time via PC (tethering for testing purposes)
